Foreword
The battle to sustain and increase corporate profitability grows ever more arduous
in most sectors of the economy. Margins are caught in a pincer movement by, on
the one hand, the steady improvement in competition and, on the other, the
increasing awareness of customers. Things are ever changing. Now we see more
businesses moving into the e-world. This has provided major opportunities to
increase business, but comes at a price. From aware customers comes the
demand for lower prices; a share of the lower costs assumed to come from doing
e-business.
There is no room for complacency. We need to grasp every opportunity not only
to be ever more effective at what we do, but also to be truly competitive, winning
more market share of the customers both nationally and globally. For success, a
full understanding of costs and cost structures is necessary. Conventional account-
ing and management reporting throw little light on the real cost dynamics in a
business. As a result we are not in control of profitability at a level of detail that
supports substantive decision-making.
Activity Based Management (ABM) is an approach that has now come of age.
ABM is not a technique; it is about management. ABM needs to be understood
and implemented by all functions so its power can be unleashed and the benefits
obtained.
Over time, ABM has evolved considerably and is now being applied in manu-
facturing, service companies, utilities, logistics, telecommunications, government
bodies and many other sectors. With ABM, businesses can make dramatic
improvements in measuring product and process costs, and more importantly
customer profitability.
Brian Plowman has created a reader-friendly, comprehensive narrative covering
the key aspects of the theory and practice of ABM. Executives and managers in all
functions in all types of organizations, as well as students, will appreciate this
book’s practical and down-to-earth approach with many practical illustrations
drawn from experience.

Foreword 9/24/01 3:02 PM Page xv
As well as step-by-step guidance on basic principles, comparisons with tradi-
tional methods, definitions of processes, activities, cost-drivers, data collection
techniques and implementation steps, this book uses numerous detailed examples
drawn from practice to build a logical picture of how to obtain the benefits of ABM.
On its own, ABM help will change management decision-making. By under-
standing how ABM also supports other profit improvement initiatives such as
Business Process Reengineering, Shareholder Value Added and Customer
Relationship Management, managers will learn how they can have the best
possible toolkit to help put the business firmly on the road to leaps in profitability.
This book should be required reading for anyone within an organization who
has the responsibility to grow their business profitably.

1 Introduction
CUSTOMERS
We know that customers are important to us. But even when we achieve the right
orientation towards customers, we know, instinctively, that some customers are
more profitable than others. We also know that some are probably loss-making.
For some businesses, this doesn’t matter much. If margins are good enough, for
whatever reason (a captive market, or a patent, or regulatory protection, and so
on), overall profitability is sufficient. But few businesses have that luxury.
We may also have some idea of which customers are the least profitable, and
which are the most profitable. A walk around the business listening to anecdotes
in different departments will tell us which customers are demanding of time and
effort and cost: these are the customers who order unpredictably, amend their
orders, change specifications at the last minute, delay payment, require special
deliveries, and so on. Every department will have its own, separate experiences of
customer behaviour. Nobody will have the whole picture. So anecdotal evidence
will pick up the extremes – the ‘worst’ and the ‘best’ customers. What about the
others?
Customer profitability is a black hole in most managers’ understanding of their
business. Identifying customer revenue is easy: it’s shown in the sales ledger.
Identifying what individual customers cost – so we can understand whether or not
they are profitable – is difficult. In a world in which competition, and often regula-
tion, put increasing pressure on margins, it is vital to understand both product and
customer profitability.
As if competition were not enough to put pressure on margins, electronic
commerce (e-commerce) promises lower unit costs and creates customer expec-
tations of lower prices.

THE TWENTY-FIRST CENTURY IS ELECTRONIC
Technology advances, rapidly. Now companies can record and process all avail-
able facts about their customers, logging their every purchase and preference,
storing details of each transaction and interaction – be it through call-centre,
e-mail or post. If customers visit a Web site, a company can know their every key-
stroke and click. And it is possible to analyse the information to death. If the
marketeers have got it right, they can predict customers’ every need and antici-
pate their every whim. Web routings, pages and menus can be programmed to
reflect the history of the customer and the actions taken on-line. Just like good
salespeople, but at a fraction of the cost, they can package and price offers not to
target a niche, but an individual. Welcome to the world of one-to-one marketing.
Buying decisions become quicker and easier because customers are proposi-
tioned only with what they find attractive, in a process they judge convenient, safe
and painless. Soon customers will have forgotten how on earth they managed in
the scrum of mass marketing when they had to do the donkey work. And on top of
all this, sales costs plummet as the need for expensive salespeople and high street
outlets, and for slow-turning showroom stock, disappears.
It is enough to make a chief executive salivate. So where’s the catch? In fact
there are two. The first is that all the competitors will be doing the same thing.
Unless a company can take an early lead and then defend its additional market
share, or unless the concoction of technology and marketing in this brave new
world increases the size of the total market, the only hope is to do it better than the
competitors – which is what organizations try to do every day. The second catch is
that all the hyperbole about e-commerce usually has a special message to the
customer. It says ‘lower prices’. After all, why do we put up with the DIY purgatory
of supermarket shopping if it isn’t for cheaper groceries? Instead of being able
to pass on to the customer the cost of all the expensive technical wizardry,
companies will find that margins are squeezed even more!
So is electronic commerce merely a development in which companies are
forced to participate as a defensive measure, to the benefit only of customers and
systems suppliers? Not necessarily.
THE MISSING DIMENSION
Customer Relationship Management (CRM) is aimed at capturing information
that will allow companies to create the circumstances in which customers will buy.
It maximizes the attractiveness of the offer and the convenience of the sale by
matching the selling process to the customer. But in making the match, it risks
driving hidden costs into the business, be it by shortening delivery lead times, by
ACTIVITY BASED MANAGEMENT
2
Chapter 01 9/24/01 3:03 PM Page 2
encouraging complex product variants, by offering high levels of personal service,
or by attracting customers who trigger excessive costs. It’s as if CRM provides a
more extravagant, indulgent courtship display, but pays no attention to the slog of
making the marriage work in the long term.
It is not enough for companies to use CRM to anticipate every interaction the
customer might have with the business, before, during and after the sale. They
must understand the costs driven by those interactions.
When the dust has settled on the expensive new e-commerce implementation
and its bewildering array of ‘bundled’ products and services, customer profitability
becomes the missing dimension, hidden deep in the business. Understanding all
the costs that are driven by customer behaviours, some of them maddeningly
cryptic, is vital to designing the processes and setting the prices that companies
offer. Otherwise, they risk making customer promises they cannot profitably fulfil.
CAN ALL CUSTOMERS BE KINGS?
Not all customers are created equal in the sight of the supplier. They behave differ-
ently from one another and have a variety of characteristics, so they generate
different costs and margins. Some are highly profitable, others are spectacularly
unprofitable, and many lie in between. Often, a small, anonymous group of
customers contributes the major share of profits, while an equally invisible seg-
ment erodes it.
A clear understanding of customer profitability allows a business to differentiate
the level of service it provides to various customer segments according to their
needs and their value to the company. For example, it may offer individual atten-
tion to prized customers in the form of dedicated telephone lines, free delivery,
incentive pricing or customized products. At the same time, it might choose to
reduce service to unprofitable customers – or to increase prices – even at the risk
of losing them. A comprehensive view of the costs that customers drive allows a
business to refine its processes and policies and focus its resources where they
will have the greatest effect on profits: cementing customer relationships; avoid-
ing excessive costs; matching prices to the service given.
In many sectors, the customer continues to provide revenue and to drive costs
well after the initial sale, through after-sales service, repeat purchasing or general
administration. All these costs, as well as the revenues, need to be identified and
analysed to ensure that the initial terms are profitable and that the customer
segments a company targets have a high probability of being profitable over the
lifetime of the relationship.
An added benefit of customer profitability analysis is that it highlights the costs
of poorly designed internal processes. As the true costs of processes emerge,
INTRODUCTION

Chapter 01 9/24/01 3:03 PM Page 3
managers can sense which costs are suspiciously high. This triggers a cycle of
further investigation, problem identification and process improvement, thereby
correcting profit-harming defects that would otherwise continue undetected.
ACTIVITY BASED MANAGEMENT
Activity Based Management (ABM) enables managers to understand product and
customer profitability, the cost of business processes, and how to improve them.
Since conventional management accounts and standard costing systems do not
provide this information, it is perhaps surprising that ABM is not more widely
used. Unlike many management techniques, research shows that 80 per cent
of companies that have employed activity-based techniques found them to be
successful.
Why? Activities consume resources – people, materials and equipment – and
this consumption can be measured. Activities are triggered by events, which can
be counted, or decisions, which can be reviewed. Activities produce outputs –
products and services, which can be counted and measured. Activities can be
undertaken by different methods, which will vary the unit cost. Activities are
linked together to form business processes. Understanding what activities are,
what they cost, what drives them, what they produce, how they are done and how
they are linked together is useful.
We have understood manufacturing activities in this way for years. We measure
the consumption of direct labour and materials in making products. On average,
however, direct labour, materials and components account for around two-thirds
of total costs in manufacturing businesses. The other, unmeasured, third is over-
head activities and costs. In service industries, the ratio is the other way round –
the unmeasured ‘overhead’ accounts for two-thirds or more of costs.
Overhead costs are the black hole in conventional management information
systems. ABM shines light into the hole. Knowledge of a business at the level of
activities is the basic building block upon which new understanding can be built
of where profits are being made and where they are being eroded.
By making visible what was previously invisible, ABM throws a spotlight on
those aspects of a business where action can directly improve business perfor-
mance. Because it deals with ‘financial numbers’, ABM is often seen as the pre-
serve of the Finance function. In fact, its real strength lies in providing genuinely
useful information for all functions in an organization. Managers throughout the
business need the right information to understand and address two key issues:
● how the company can position itself better in the market – for which accurate
product and customer profitability information is vital
ACTIVITY BASED MANAGEMENT
4
Chapter 01 9/24/01 3:03 PM Page 4
● how it can improve its internal capability and lower unit costs – for this, it needs
to understand and change the procedures, systems and processes that create
products and deliver services to customers.
Most organizations are complex. Building an ABM model of a business requires a
structured approach and the dedication of a team to achieve a result in a reason-
able timescale. But building a model is only the start. Embedding ABM into the
business means giving managers not only a new understanding of what drives
costs, but the means to measure and act on the drivers to reverse adverse trends.
ABM is about management. This book is intended for ‘general management’ in
any type of organization. The following chapters discuss the basic principles of
the approach, describe how to approach the development of ABM models and the
implementation of ABM thinking in a business, and use numerous case studies to
illustrate how ABM can make a difference to business performance.
KEY POINTS
● We know customers are important but without knowing the costs that
customers impose on us, we’ll never know which ones are profitable.
● When we know the costs that are driven by customer behaviours, we can differ-
entiate the level of service we provide to various customer segments.
● In manufacturing businesses, direct labour, materials and components
account for around two-thirds of total costs. The other, unmeasured, third is
overhead activities and costs. In service industries, the unmeasured ‘overhead’
accounts for two-thirds or more of costs.
● ABM helps companies position themselves more advantageously in the
market by providing accurate product and customer profitability information.
● ABM helps companies to improve their internal capability and lower unit costs.
● ABM is often seen as the preserve of the Finance function. In fact, its real
strength lies in providing genuinely useful information for all functions in an
organization.
● E-commerce channels currently give certain companies cost advantages. But
not for long. Competitors will soon be doing the same thing.
● In e-commerce, customers want a share of lower costs, reflected in lower
prices. In the future, it will be even more important to know customer
profitability.

2 Historical perspective
THE FIRST SERIOUS QUESTIONS
In the late 1980s and throughout the 1990s, the relevance of traditional accounting
practices was seriously questioned. Conventional costing, budgeting and manage-
ment accounts became ever less able to support the business decisions that were
now relevant. The relevance debate was founded on three key criticisms.
The first criticism was levelled at the lack of technical developments in manage-
ment accounting practice despite major changes in manufacturing technology.
These major changes had resulted in greatly increased productivity, flexibility and
quality, together with reduced lead times and inventory. Further, the significant
changes in the proportions of ‘direct’ costs to ‘overheads’ had created major distor-
tions in calculating product costs based on simplistic overhead recovery rates.
The second criticism held that management accounting was nothing more than
financial reporting, leading to information that was too distorted, too aggregated
and too late to be of much value to management.
The final criticism was concerned with the history of management accounting.
A mature management accounting tradition was well established in the 1920s. In
those days, traditional accounting had served business needs well in terms of cost
management, management controls and performance measurement. However,
the worldwide dominance of accountancy practice, standard training and examina-
tions means that significant inertia towards change still exists.
The relevance discussions were published during a period of concerns over
America’s need to regenerate its industry in the context of the emergent global
economy and the lessons from the success of Japan at that time. The moves in
management accountancy were towards cost management and away from cost
accounting. Developments since have included a concern with understanding
such aspects as value-adding processes, life cycle costing, market-driven target
costing, product and customer profitability, customer relationship management,
Shareholder Value Added and the emergence of e-commerce.

NEW COSTING APPROACHES GATHER PACE
Costs have been addressed in many ways in businesses, although traditional prac-
tice had formed around the major manufacturing sectors. The key problems with
trying to determine accurate product costs started to gain the attention of a body
called CAM-I (Consortium for Advanced Manufacturing – International). This
body researches all aspects of the manufacturing sector in its struggle to come to
terms with the changes that modern methods have introduced.
The CAM-I Cost Management Systems (CMS) Program is internationally
recognized as a leading forum for the advancement of cost and resource manage-
ment practices. Organized in 1986 as a coalition of leading thinkers from industry,
government and academia, the CMS Program has accomplished extensive
research and development of new management methods. The CMS Program is
acknowledged worldwide for raising the awareness of Activity Based Costing
(ABC) and Activity Based Management.
Although the manufacturing sector was the first to find that traditional account-
ing had lost its relevance, the service sector began to catch up. In financial
services, what is a direct cost, and what is an overhead? Tracking the real cost of
its products, services and customers became an issue as the recession and severe
competition started to erode the traditional safe profits in banks and insurance
companies.
In the utilities sector, the problem had grown rapidly with the changes in legis-
lation that created greater competition. The ‘regulator’, who wanted to ensure
visibility in a company’s costs and put constant downward pressure on prices,
further complicated the situation. Where there are virtual monopoly suppliers of
services, the UK Monopolies and Mergers Commission is keen to gain access to
the real costs of providing products and services, and handling customers.
Another perspective is through the value chain. The term Efficient Consumer
Response (ECR) has been coined to encapsulate improving the chain that
stretches from the basic raw material sources of a business through to the ultimate
consumer. Generally, firms are only involved in part of the overall chain of value-
creating activities, and therefore must endeavour to develop information that
permits internal cost management and allows information to cross the company’s
boundaries. Activity-based approaches form the foundation on which information
and costs are analysed throughout the value chain.
The new millennium has brought the prospect of a new dawn to many busi-
nesses. But all types of companies are finding that they are still in the dark. Their
traditional accounting and costing methods remain unable to provide the answers
to very relevant business questions, such as:
PART I: THE CONTEXT
10
Chapter 02 9/24/01 3:04 PM Page 10
● How do we measure commercial success?
● Which parts of our process add value, or not?
● Do we make profitable products, and provide profitable services?
● Which is our most profitable customer?
● What can we afford to negotiate away?
● Which type of distributor is important to us?
● Do some products subsidize others, and if so, by how much?
● Are some of our customers targets for our competitors?
● Are we going for volume at the expense of profits?
● What is the real contribution from our product range?
● How should we invest this contribution from our current products?
● Should we go for new products or new markets?
● Will our new e-commerce channel provide the profits we yearn for?
Most of these questions have always been asked. It is management’s job to answer
them. But while struggling to feed ever more irrelevant budgeting systems and
answer monthly management accounts variance queries, management has had to
fall back on ‘gut feel’. This is a poor substitute for appropriate information. ABM
fills the chasm so long filled with inappropriate information.
KEY POINTS
● The relevance of traditional accounting practices has been seriously ques-
tioned. Criticisms concern the distortions in calculating product costs based on
simplistic overhead recovery rates, financial reporting that is too distorted to
be of much value to management, and the worldwide dominance of accoun-
tancy practice, standard training and examinations, creating a significant
inertia towards change.
● The foundations of ABM were built on the manufacturing sector, but the
service sector has rapidly caught up, driven by regulatory and competitive
pressures.
● Activity-based approaches form the foundation on which information and costs
are analysed throughout the value chain.
● Traditional accounting and costing methods remain unable to provide the
answers to very relevant business questions. ABM has filled the gap.

3 What is ABM?
Initially, Activity Based Costing (ABC) was presented as a means of establishing
product costs more accurately. The emergence of Activity Based Management
(ABM) provided a means of enhancing profitability. ABM is underpinned by a
theory of resource consumption, with activities viewed as giving rise to costs, as in
ABC, but taking the analysis further in a way that provides management with
insights into managing the business overall. Essentially, these insights are
focused on a process view of the business and a deeper understanding of product,
channel and customer profitability.
COSTING AND PROFITABILITY
The ledger, budgeting and monthly management accounts are based on reporting
resources: those planned to be used, the consumption month on month and the
variances from plan. Resources are those things that provide the means to allow
work to be done in the organization: salary costs for the people doing the work,
accommodation costs so that people can work in buildings, utilities so that people
can see what they are doing and keep warm, vehicles so that goods can be
delivered and customers visited. In some cases, the list of types of resource on the
ledger may seem endless.
But no matter how long the list of resources, nothing in the ledger or the man-
agement accounts tells us how the resources are being consumed in doing things,
to what purpose, or in what way. Resources are consumed by activities and it is at
this level of analysis that we see what is actually being done. At this level we can
also take a view on whether the activities that are being performed are necessary.
We can also find out whether the activities are being done well and use the best
methods, and so take the business forward, or whether they are really only sorting
out problems that are dragging the business back.
13
Chapter 03 9/24/01 3:05 PM Page 13
Activities are undertaken for many purposes. Some directly manufacture prod-
ucts, while others indirectly support manufacture, such as the Quality department
or materials handling. Some activities support the business as a whole, such as
recruitment and training or the parts of the IT department that keep the network
running.
Other activities are directly associated with customers, such as the salesforce,
or more indirectly within the Credit Control department. Other parts of the busi-
ness are working on activities to create a better future, such as New Product
Development, and others are working on influencing potential customers, such as
Marketing and Advertising.
Some parts of the business have little to do with products, services or customers
but are necessary to keep the business legal, such as statutory reporting or orga-
nizing the shareholders’ annual general meeting or preparing for the annual audit.
Activities are the very engine at the heart of the organization. Understanding
what is done, how it is done, what causes it to be done and why we are doing it
gives us a better chance of deciding whether we are getting the best value from the
resources we deploy. As a simple analogy, budgeting and reporting on the differ-
ent amount of food we eat may be mildly interesting but what people then do with
their time having consumed the resources is what influences the world around
them, for better or worse.
In conventional accounting, and particularly in manufacturing companies, costs
are categorized into two main types: direct costs and overheads. Direct costs
include the employees manufacturing the products, and the raw material they use.
Overheads are the rest. The problem then arises when the costs of the products
need to be calculated. Although we will look at this in greater detail in later
chapters, we can say at this point that an ABM analysis accurately assigns the
costs of those overheads that are actually influenced by the products being made
or the services being provided.
Having derived accurate product costs, ABM goes further and analyses the
costs of servicing each customer or specific segments of the customer base.
Customers create a wide range of differing costs for a host of reasons.
The key insight that ABM exposes arises when revenue is brought into the
equation. When the actual costs of the products or services going to a particular
customer are calculated and the actual costs of servicing that customer derived,
we can compare these figures to the revenue from the customer, as shown in
Figure 3.1. Revenue minus the product costs gives the ABM Product Contribution.
Revenue minus the product costs minus the costs of servicing the customer gives
the ABM Customer Contribution. The sum of all the customer contributions has to
pay for all those remaining costs that are not associated with the current products
or customers, such as new product development and statutory accounting.
Anything left after that is the profit.
PART I: THE CONTEXT
14
Chapter 03 9/24/01 3:05 PM Page 14
It is at the level of ABM Product or Customer Contribution that we use the term
‘Product and Customer Profitability’, as it is at this level that meaningful compar-
isons can be made between products and between customers. It is this type of
analysis that exposes small or negative values prompting a serious review of which
products or customers to keep, or at least a decision to take action to try to turn the
relationship into one that provides positive contributions. We will look at this later
in greater detail, as this insight into a company’s costs is the central advantage of
using ABM analysis.
By understanding how costs relate to those factors that drive the costs, we
can use the powerful approach of Activity Based Budgeting (ABB). Rather than a
futile circular argument revolving around resources, such as just asking for more
people, the debate focuses on the drivers of cost that influence how much activity
is actually required. ABB analyses the products or services to be produced, and so
determines the level of the activities required. The level of activities then deter-
mines the resources to be budgeted. When automated, ABB can rapidly and
accurately produce financial plans and models based on varying levels of volume
assumptions.
The more obvious volume assumptions would take into account levels of

product or service being provided. More subtle assumptions would take into
account, say, the projected numbers of staff to be recruited, and hence the impacts
back into the personnel and human resources activities, and thus resources. From
the customer perspective, providing more volume of the same products to the
same customers would have one set of impacts on activities. In another scenario,
additional new customers placing orders for half the previous average quantity per
order line but for an average of double the number of order lines per order would
have a quite different impact on activities, and thus overall resources, in various
functions. This is the stuff of the real world, where real things are happening.
Sitting in a functional silo with no knowledge of what actually drives the costs in a
function makes guessing the resources required for the next twelve months one of
the most futile exercises that has ever been invented. This probably accounts for
the long, sad faces when the budget round is announced.
Using activity-based target costs throughout the product design and develop-
ment process brings the real world of the competitive marketplace right into the
start of the process that creates costs. Gone are the days when companies could
design a product, work out its costs, add a bit for overheads, then announce the
price. To grab market share and ensure sustainable growth, a company has to
know beforehand the price that will ensure the product’s success. At the design
and development stage, more than just the direct costs are designed in. At this
stage, the company has to think through all aspects of the processes in the busi-
ness affected by the product or service so that it does not breach the target cost.
PROCESS IMPROVEMENT
An organization is a series of activities that combine in processes to create valu-
able products or services for customers. It is the effectiveness of an organization in
performing these processes – to create high value at low cost – which marks out a
successful company. Most of a company’s significant processes travel across func-
tional boundaries, and it is at these boundaries that delays and quality problems
occur.
ABM focuses on the company’s processes. If the processes are understood then
failure activities can be eliminated from those processes. Value-adding activities
can be examined to see whether better methods can be used. Time delays and
quality issues can be addressed at the point in the process where they occur. ABM
is the management of improvement through the analysis of business processes,
and their associated activities. This analysis is carried out systematically and
cross-functionally so that improvement projects can be readily implemented and
the changes monitored.
ABM is an approach that involves many people within the organization, and is:
PART I: THE CONTEXT
16
Chapter 03 9/24/01 3:05 PM Page 16
● a vehicle for creating process improvement – both incremental, continuous
improvement and radical restructuring of the organization
● a model to show how costs (and revenues) are created through processes and
activities – if you understand the activities, then you can understand the costs;
if you understand the processes, then you understand the business
● a means of measuring the company’s progress in the key areas of the business
that need change and improvement.
We will look at this use of ABM in greater detail later, as the insights gained from
process analysis are central to reducing unit costs, eliminating waste and improv-
ing levels of service to customers.
Although ABM can be used to address a specific project or process that needs
improvement, it is at its most effective when the company uses ABM as a standard
approach to business improvement. This way, the entire organization can be
involved in process improvement, and over time every process within the com-
pany can be studied, and changes initiated.
KEY POINTS
● Nothing in the ledger or the management accounts tells us how resources are
being consumed in doing things, to what purpose, or in what way.
● Activity analysis allows us to find out whether the activities are being done well
and use the best methods to take the business forward, or whether they are
really only sorting out problems that are dragging the business back.
● Revenue minus the total product costs gives the ABM Product Contribution.
Revenue minus the product costs minus the total costs of servicing the
customer gives the ABM Customer Contribution.

new product development and statutory accounting. Anything left after that is
the profit.
● It is at the level of ABM Product or Customer Contribution that we use the
term ‘Product and Customer Profitability’, as it is at this level that meaningful
comparisons can be made between products and between customers.

how much activity is actually required. ABB analyses the products or services
to be produced, and so determines the level of the activities required. The level

Frameworks for measurement
4 and improvement
Although ABM can be used as a stand-alone approach to understand processes,
product and customer costs and profitability, it provides a more powerful means of
decision support if it exists as part of a larger framework of measures.
Over the years, a number of frameworks have been developed, each endeavour-
ing to arrive at a more rounded perspective on the business and a reduced empha-
sis on the previous domination of financial measures.
Although traditionally profit has assumed the dominant role as a measure, the
many means of its attainment are recognized as being much more varied and com-
plex to measure and control. Consequently, as well as being concerned with sales
and margins, it is necessary to have information on such things as production
times, component commonality, quality initiatives, customer satisfaction, cus-
tomer service activity, employee skill development, employee turnover, legislation
changes, environmental impacts and many other variables in the business. In fact,
any element of performance can be important if it is related to success in the
marketplace. Their integration has been more formally recognized by the use of a
number of frameworks that attempt to bring a more rational balance to the variety
of measures used in the business. ABM is a key component of these measurement
frameworks.
THE BALANCED SCORECARD
Professors Kaplan and Norton first described the Balanced Scorecard in an article
in the Harvard Business Review in 1992. The term ‘balanced’ reflects the objective
of reporting to stakeholders other than the owners of the business, as well as in
ways quite different to financial reporting. The Balanced Scorecard includes four
perspectives, as shown in Figure 4.1. As well as the more traditional measures
found in the financial perspective, the scorecard includes customer, internal
business, and learning perspectives.
19
Chapter 04 9/24/01 3:06 PM Page 19
The customer perspective can include measures of quality, lead times, reliability
and customer service as these impact on customer satisfaction, repeat business
and referrals. The internal business perspective is concerned with processes and
productivity. Crucially, there is a recognition that the workforce is a vital stake-
holder whose skills and commitment to the organization cannot be taken for
granted. The fourth perspective, that of learning and innovation, is concerned with
performance improvements and the ability to introduce successful new products
and services. All four perspectives reflect the need to sustain a strategic position in
the marketplace to create value for shareholders, provide challenging employ-
ment opportunities for the workforce and enjoy a sustained partnership with
customers, both corporate and consumers. It is therefore imperative that an
appropriate range of measures exists to integrate in the scorecard.
A by-product of using a Balanced Scorecard is that, throughout the organization,
it raises the awareness of measures, in a language that people can understand in
their own areas of responsibility and influence. However, where useful informa-
tion is lacking, ABM becomes a powerful tool to understand and answer funda-
mental questions that arise around processes, products and customers. Profitable
customers served by ineffective processes will not lead to success. Impeccable
processes serving unprofitable customer segments will also drag the company
down. If employees focus their learning and innovation on products and services

that attract disproportionately high but largely invisible costs, it can bring a busi-
ness to its knees. The Balanced Scorecard by itself is not a guarantee of corporate
success. The underlying behaviour of costs and an understanding of what drives
costs provide the knowledge and insights to drive improvements. In this respect,
ABM is a fundamental building block.
THE BUSINESS EXCELLENCE MODEL
The European Foundation for Quality Management (EFQM) Business Excellence
Model arose during the time that ‘quality’ and ‘total quality’ had ascended to the
highest point of management’s consciousness. The quality movement had tended
to follow the course of ISO 9000, an international standard that focuses on quality
systems within the business. In response to this trend, a number of companies
leading the quality movement searched for a means of describing a business
across a range of features that went beyond just looking at the internal quality
systems.
This endeavour led to the formation of the EFQM and the publication of the
Business Excellence Model. The model defines nine elements as shown in Figure
4.2. Five elements are known as enablers, and the remaining four are the results.
Each element has a weighting, and when taken as a score, a company with a total
of 80 per cent or more is recognized as achieving excellence. In Europe, such high
scores put a company in the running for the annual European Quality Awards.
Interestingly, a company that states that it has implemented ABM as an
approach to inform and change its scoring on a number of elements only achieves
an enhanced score if it actually produces the ABM information and acts on it.

Setting up an ABM programme but failing to apply its findings will count against a
company.
SHAREHOLDER VALUE ADDED
The measure of Shareholder Value Added (SVA) is unashamedly financial. SVA,
the generic term (also known as Economic Value Added), was introduced as a
measure by the American consulting firm Stern Stewart & Co. Their term and the
three-letter acronym, EVA are both trademarks of their company. The definition is
simply: Shareholder Value Added equals the net operating profit after tax minus
the capital charge.
The net operating profit after tax brings into focus prices, volumes, the cost of
sales and all the operating expenses in the business, as well as taxes. It is therefore
imperative that the business knows which products and customers are profitable,
and why, and that its processes operate at the lowest unit cost. Whatever tech-
niques or approaches are used to achieve these ends, it is important that informa-
tion in the business is structured to support the right decision-making. ABM is a
building block to create this knowledge.
The capital charge is all capital (net working capital plus net fixed capital) multi-
plied by the cost of capital. Capital comprises working capital (debtors, creditors
and inventory) plus fixed capital (property, plant and equipment). Actions to
reduce debtor days and work in progress would be simple examples of increasing
the value in the business. Investing in capital equipment focused on profitable
products to profitable customers requires greater finesse in ensuring that the
right decisions are made.
All financial measures, including SVA, tell us the outcome of many different
things, but they usually hide the causes of good or bad profitability. The good or
bad performance of individual processes is seldom visible in financial performance
measures, and the real profitability of products and customers is completely
obscured.
Depending on the type of business, actions to increase value will differ. Inside
an SVA measurement framework, ABM is the means to actually influence the
value drivers in the business. It is this knowledge that makes a difference so that
people can make decisions and take actions to increase value.
POSITIONING AND CAPABILITY
The collection of measures encapsulated within the term ‘positioning and
capability’ was developed by the UK consulting firm Develin & Partners, and is
PART I: THE CONTEXT
22
Chapter 04 9/24/01 3:06 PM Page 22
founded on the principle that organizations need to make a series of steps from
where they are now to some future goal. To guide the company on its journey to a
future goal, a ‘map’ is required, where the axes of the map are positioning and
capability. The basic map is shown in Figure 4.3.
Positioning is to do with external factors, such as:
● understanding customer needs
● understanding product and customer profitability
● understanding competitor initiatives
● determining the business’s financial needs
● complying with changing legislation
● meeting environmental constraints.
Getting positioning right leads to higher levels of revenue through providing prof-
itable products and services, increasing market share, increasing the size of the
market, and by retaining profitable customers.
Capability is to do with internal factors, such as:
● key business processes
● procedures and systems
● competencies, skills, education and training
● attitudes, style and behaviours.

Figure 4.3 The journey of change
Chapter 04 9/24/01 3:06 PM Page 23
The capability is changed to deliver the desired positioning. Capability creates the
costs in the business. The journey joins revenue and cost. Getting the balance
right between positioning and capability enhances profits and the value of the busi-
ness.
ABM is the vehicle by which companies journey along their chosen route. ABM
informs key aspects of positioning, particularly when used to provide accurate
product costing and to derive product and customer profitability. ABM informs
key aspects of capability, particularly when used to understand process costs, fail-
ures within processes, and to establish the link between costs and the drivers of
cost.
ABM provides the basis for management to make better informed decisions,
both on positioning and capability. In other words, the company can determine
which products, markets and customer segments it wishes to retain, it can make
relative pricing decisions based on competitor initiatives, and it will be able to
focus on those aspects of capability which leverage profitability through process
improvement and a reduction in unit costs.
Using ABM during the positioning work provides an opportunity to undertake
customer engineering as an action to guide changes in capability. Avoiding a cer-
tain activity may then be an initial action, rather than spending effort on improving
what could be an unnecessary process. ABM analysis of the current business,
prior to making changes to any processes, can answer a number of positioning
questions:
● Can the salesforce be directed towards more profitable segments in relation to
the costs of servicing the business that is generated?
● Will a switch away from volume selling to focused selling improve short-term
profitability?
● Can some customers or product lines be dropped and achieve an increase in
company profitability?
● Can we apply discounts more effectively to achieve volume and know that we
will remain profitable?
● Can we switch some customers to wholesalers or other third parties, rather
than service every customer ourselves?
ABM is the way to link a company’s trading relationships (positioning) to its
internal cost structure (capability). The basic premise is that activities consume
resources and convert them into products and services to customers. Costs are
therefore the consequence of resource decisions, and income is the consequence
of linked activities, the business processes. The requirement is therefore to
improve resourcing decisions as the means of managing costs, and to improve
processes as the means of improving business effectiveness and thus customer
service and revenue.
24
PART I: THE CONTEXT
Chapter 04 9/24/01 3:06 PM Page 24
In the positioning and capability framework, ABM plays a key role in informing
the journey. On the positioning axis, ABM is used for profitability management,
such as costing and profitability analysis, customer and product mix decisions,
and support for marketing decisions. On the capability axis, ABM is used for
resource and performance management, such as resource and service level
changes, activity-based budgeting and cost driver analysis, and for process
improvement to eliminate process failures and reduce unit costs.
KEY POINTS
● The integration of many elements of performance has been more formally
recognized by the use of a number of frameworks that attempt to bring a more
rational balance to the variety of measures used in the business. ABM is a key
component of these measurement frameworks.
● The Balanced Scorecard includes four perspectives: financial, customer,
internal business, and learning. The underlying behaviour of costs and an
understanding of what drives costs provide the knowledge and insights to
drive improvements. In this respect, ABM is a fundamental building block.
● The EFQM’s Business Excellence Model defines nine elements. Five ele-
ments are known as enablers and the remaining four are the results. ABM is an
approach to inform and improve the scoring on a number of elements.
● Shareholder Value Added equals the net operating profit after tax minus the
capital charge. ABM is the means to influence the value drivers in the business
that will help increase SVA.
● Positioning is to do with external factors, and getting this right leads to higher
levels of revenue through providing profitable products and services, increas-
ing market share, increasing the size of the market, and by retaining profitable
customers.
● Capability is to do with internal factors, a change to which delivers the desired
positioning. Capability creates the costs in the business. Positioning and capa-
bility thus join revenue and cost. Getting the balance right enhances profits
and the value of the business.
● The journey of change can be mapped using the two axes of positioning and
capability. ABM provides the information for both axes, to plan the journey and
measure how far you have travelled.

5 The ABM framework
In Chapter 4, we saw how ABM fits into a number of overarching frameworks of
measurement and improvement. In Chapter 6, we will see how ABM is used in a
real-life example, to illustrate how ABM handles costs, assigning them to activities
then onwards to products, channels and customers.
However, before going into an example it is wise to take a few moments to
describe how ABM views the treatment of costs, which differentiates it from tradi-
tional accounting approaches. This chapter explains the way ABM handles costs
and the characteristics of activities compared to conventional approaches, as well
as introducing the language of ABM.
TRADITIONAL RESOURCE ACCOUNTING
Most established accounting systems usually capture and distribute resource
costs based on one or more of the following methods:
1. organization structure or cost centre accounting
2. budgetary accounting
3. cost allocation accounting.
From their longevity of practice, we must assume that in the past they have
met the needs of organizations to some degree. Yet every one of them fails to meet
the full requirement for management information that will adequately support
decision-making in today’s competitive environment.
COST CENTRE ACCOUNTING
This is a popular method for applying resource costs to an organization. The
accounting system identifies each of the organizational parts of the traditional
functional structure and applies the identifiable costs to that part of the structure.
27
Chapter 05 9/24/01 3:07 PM Page 27
In many traditional organizations, the only costs that are identified to the organiza-
tion’s functional departments are the salary costs. Although overhead costs are
sometimes distributed to cost centres, it is more common to find that these costs
are ignored at the unit level. Many overhead costs are held centrally by the
providers of services, and not sub-divided to the users of the services. For exam-
ple, the cost of ‘vehicles’ would be held in the function or department that looks
after the vehicles. The cost of ‘postage’ would be held in the postroom where the
mailing physically takes place.
This system was created to provide management with some information on the
costs of the organization’s departments. Some argued at the time that this would
make ‘controllable’ costs visible to those managers that have to control the costs.
However, under cost pressure the owners of resources supplied to others would
turn the tap down or off. The Stationery department refusing to issue paper for
other departments’ photocopiers is a result of this approach to cost control.
Where attempts to obtain a true picture of departmental costs are applied, man-
agers of resources that are supplied to others apply cross-charges to users, based
on a rate for the service. The rate is based on a collection of costs the service
department actually incurs, such as its own staff salaries, to which it adds a
mysterious amount to cover its own overheads and the costs that it has received as
cross-charges from others. The cross-charging game can reach heights of absur-
dity when internal sub-divisions of the organization are made into profit centres.
The charge-out rate then includes a bit extra, which it calls ‘profit’. In some
instances, this accumulating figure is then used to purchase something from out-
side on the basis that it is using spare income, and not a departmental cost. From
the organization’s perspective, this is real money going out the door. However,
trying to get accurate costs to the place in the organization where the budget for
the funds is held can also create absurd situations, as the following example aptly
illustrates.
CASE STUDY
A company introduced a simple method to improve the cost-effectiveness of the
use of taxis. By arranging to use a single supplier, any travellers only had to
print and sign their name against the meter cost recorded on the taxi’s log
sheet. To prevent fraud, the passenger retained a tear-off copy slip showing the
cost. On a monthly basis, the taxi company presented its itemized bill, which a
clerk in Accounts dutifully used to look up where each passenger worked. The
cost centre manager’s name and cost centre number were also looked up and
noted. The annotated invoice then started its journey around the site for each
manager to authorize and add the cost centre allocation number for taxi

journeys to the invoice. Later, these costs would be accumulated and reported
to each cost centre manager.
Three months later, the irate taxi company would begin to demand payment.
The problem for the Accounts department was knowing where the invoice was
in its journey around the site. In a year, 40 per cent of the invoices never found
their way back to the Finance function. The taxi company would regularly
threaten court action to secure payment. Accounts Payable would just ask for a
faxed copy of the invoice and pay the same day on receipt of the fax.
Finally, someone did question whether the whole process added any value,
or whether it just added unnecessary cost.
In all this striving for accuracy, accountability and control, hardly any real attempt
is ever made to trace costs to the activities or process flows in organizations or to
the ultimate output, the products and services for customers.
BUDGETARY ACCOUNTING
The tracking of costs to a budgetary account is often combined with cost centre
accounting. In this case, the major concern of the spenders of resources is to
ensure that their total expenditures do not exceed the allocated budgetary
amounts. Consequently, accounting systems become a safeguard mechanism to
capture commitments, undelivered orders, and expenditures, normally divided
into the cost centres that reflect the organization structures, to enable tracking of
actuals, budgets and variances. The measure of success, and thus the major objec-
tive of each accountable manager, is to use the resources assigned fully, rather
than enhancing productivity or reducing expenses. In some types of organization,
any attempt to conserve resources or work more effectively to come under budget
runs the risk of prompting a reduction in the future budget resource level. The
budgetary control mechanism can reach heights of absurdity.
CASE STUDY
In a government research organization, the scientists received funds to under-
take research projects. Towards the financial year end, the researchers had
unspent funds, but there were insufficient hours of research capacity to conduct
the research before the year end. The fund providers wanted the funds spent
(for fear of their own funds for the following year being reduced), but were only
concerned that the money was spent on ‘project-related’ costs. In this case, buy-
ing equipment was acceptable. As specialist equipment would be pointless, the

researchers looked for something more generic. Two weeks later, three large
vehicles arrived on site delivering top-of-the-range-desktop computers.
As there was no immediate scientific purpose for the computers, they
remained in their boxes and researchers used them as additional seats. Among
the support departments, frustrations reached boiling point when they saw the
vehicles being unloaded. The cap on their costs always prevented them procur-
ing decent equipment. Worse was to come. Given the different funding regimes
for the two groups, the overhead functions were not allowed to use the spare
computers languishing in their boxes.
Like cost centre accounting systems, budgetary control mechanisms make no
attempt to cost the outputs of all the work, or in many cases to even bother to
define the output. If real customers are at the end of a supply chain of activities in
such environments, then their needs can be well down the list of priorities, with
‘meeting the budget’ firmly at the top.
COST ALLOCATION ACCOUNTING
Where an organization has the characteristics of a business then it generally has a
need to distribute its costs to an output so that it can price its products or services.
Revenues also come into the picture, and we talk about ‘revenues minus total cost
leaves us the profit’. To make the costs visible, ‘true’ cost accounting systems were
established to capture and distribute costs to the outputs, such as goods or ser-
vices. These cost accounting systems use the classic model of cost distribution
which was designed around the major sector of the economy at the time: manu-
facturing. In this system, the focus of gathering costs and collecting them under
generic headings relied upon the simple classifications of direct labour, direct
materials, and overhead. Businesses and business-like organizations have relied
upon the historical model of cost accounting for over a hundred years.
However, the traditional cost accounting methodology does create significant
inaccuracies in output costs because of the manner in which overhead costs
are apportioned to output rather than assigned or traced to output. When this
erroneous method of cost distribution finds its way into the ultimate price of the
output, it leads to poor management decisions about which products or services to
promote hard, or which to discontinue, and which customers it should sell to or
drop.
As traditional accounting has such a grip on most organizations, we would argue
that it is in the areas of the fundamental flaws it contains that ABM really makes a
difference. In particular, ABM is superior to traditional accounting in a number of
ways:
PART I: THE CONTEXT
30
Chapter 05 9/24/01 3:07 PM Page 30
● ABM provides visibility in the way costs flow through the business.
● ABM establishes the links between activities and those factors, internal or
external, that drive the level of activity up or down.
● ABM eliminates the false divide between direct costs and overheads.
● ABM separates out those costs that deal with today’s business from those that
secure the future.
● ABM ignores gross margin and uses accurate product and customer contribu-
tions as the basis for comparing product and customer profitability.
● ABM exchanges functional myopia for a cross-functional process view of the
organization.
● ABM exchanges the stilted definitions of value-added and non-value-added for
sensitive categories that highlight the subtle impact of internal process failures
and external customer behaviour.
ABM VERSUS TRADITIONAL TREATMENTS OF COSTS
At many levels, ABM brings a different perspective to how costs are treated. ABM
challenges the traditional approaches to product costing, gross margins, profit-
ability, functions and hierarchies, value-added and non-value-added, and budget-
ing.
TRADITIONAL PRODUCT COSTING
It is in the area of product costing that serious weaknesses in the traditional
approach first became a cause for concern. In the days when traditional account-
ing practices were being formed and internationalized, the dominant industries
were in the manufacturing sector. In a typical large manufacturing company, there
would be large numbers of employees concerned with direct manufacturing and a
much smaller number in the overhead departments.
In a situation where the direct labour costs could be as high as 90 per cent and
overheads 10 per cent of total costs, it was important to achieve some accuracy in
terms of the hours, and therefore costs, required to make components and assem-
blies. Work-study and other techniques found a ready use in determining the
direct labour content of any product. The direct material costs were also simple to
calculate for each product, based on raw material content, scrap rates, bought-out
parts and so on. Working out how much of the overhead activity was actually asso-
ciated with each product was seen as a lot of effort for such a small improvement in
the accuracy of the product cost. This led to the use of the Overhead Recovery
Rate (ORR) as the fundamental method of product costing.
To derive a method of calculating the proportion of overheads to allocate to each
THE ABM FRAMEWORK
31
Chapter 05 9/24/01 3:07 PM Page 31
product, a simple ratio was derived, known as the ORR. A company would simply
find the overall ratio between total overhead costs and total direct labour, say 10
per cent. The direct labour for each product made, and any new ones developed,
would then have 10 per cent added to account for the overhead, and so give the
product cost.
As manufacturing became more complex, the proportion of overhead activities
to direct activities started to increase. Product costs now became far more sensi-
tive to the indirect and overhead costs associated with each product. The tradi-
tional ORR became highly suspect as a means of calculating product costs. Some
products could be seriously under-costed, and thus probably highly competitive,
but an increase in sales volume would actually erode profitability. Conversely,
over-costed products would be unattractively priced, and few sales made.
As the proportion of overhead costs increased in a business, the more serious
the distortion in product costing became through using the ORR method.
ABM PRODUCT COSTING
In ABM, the indirect and overhead costs are determined for each product. The
characteristics of two products can be quite different in the way they need over-
head activity to support manufacture.
CASE STUDY
A company that had traditionally made its name manufacturing bogies for rail-
way trucks and carriages had branched out into making braking systems for
long-haul diesel road vehicles. While the technology surrounding the railway
business had not developed significantly over the years, the road vehicle tech-
nologies had advanced in complexity at a rapid rate. Using direct labour as the
determinant of the proportion of overhead costs had led to over-priced railway
products and under-priced road vehicle products. The growth in the road
vehicle business then seriously eroded overall profits, and the stable rail
business was drifting to competitors.
Figure 5.1 shows two of the company’s products costed using the conven-
tional ORR, in this case 300 per cent. For product Pr1, the direct labour had 50
units of cost, so the manufacturing overhead was assumed to be 300 per cent of
this: 150 units of cost. Product Pr2 again used 300 per cent, and this was applied
to the direct labour cost of 200 units, giving a manufacturing overhead of 600
units of cost. Using a conventional ORR took no account of the real differences
in the amount of overheads that either product required.
PART I: THE CONTEXT
32
Chapter 05 9/24/01 3:07 PM Page 32
Product Pr1, a road vehicle braking system, was complex, had many produc-
tion changes, and used difficult manufacturing technology. There were also
many discussions with specialist suppliers.
Product Pr2, a railway truck bogie, used simple manufacturing technology,
enjoyed a steady demand with few changes to schedules, and had used the
same suppliers of raw material over a long period.
Using the ABM approach, the direct and actual overhead costs reflected the
real situation, as shown in Figure 5.2. Note that for Pr1 the conventional
approach gave a contribution nearly double what it actually was. In other words,
in reality the product was less profitable than they thought. Conversely, Pr2
was much more profitable than they thought. Using the overhead recovery
approach meant that Pr1 was under-priced. They had orders, but made little
profit. Sales of Pr2 could be higher if it wasn’t over-priced.

TRADITIONAL VIEW OF GROSS MARGIN
In traditional accounting, we find the term ‘gross margin’, defined as the revenue
minus the direct costs. As long as the gross margin is a positive number, then the
product is deemed to make a ‘contribution to overheads’. In other words, whatever
the overheads actually are, at least there are some funds to pay for them. The issue
is that we do not know, other than at the overall company level, whether this con-
tribution has any bearing whatsoever on the real overheads involved in producing
each particular product.
ABM VIEW OF PRODUCT CONTRIBUTION (PRODUCT PROFITABILITY)
In the product costing examples above, the ABM analysis uncovered the actual
indirect and overhead costs associated with producing each product. Now when
we calculate the revenue less the actual product costs, we have a number that is
called the ABM Product Contribution. In other words, if this is a positive number,
then we know that product costs are covered and the sum left over now con-
tributes to the other overhead costs in the business such as sales, R&D, invoicing
and so on.

electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers.
It exists because of the efforts of hundreds of volunteers and
donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg™’s
goals and ensuring that the Project Gutenberg™ collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a
secure and permanent future for Project Gutenberg™ and future
generations. To learn more about the Project Gutenberg Literary

Section 4. Information about Donations to
the Project Gutenberg Literary Archive
Foundation
Project Gutenberg™ depends upon and cannot survive without
widespread public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can
be freely distributed in machine-readable form accessible by the
widest array of equipment including outdated equipment. Many
small donations ($1 to $5,000) are particularly important to
maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and
keep up with these requirements. We do not solicit donations in
locations where we have not received written confirmation of
compliance. To SEND DONATIONS or determine the status of
compliance for any particular state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where
we have not met the solicitation requirements, we know of no
prohibition against accepting unsolicited donations from donors in
such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of
other ways including checks, online payments and credit card
donations. To donate, please visit: www.gutenberg.org/donate.
Section 5. General Information About
Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project
Gutenberg™ concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg™ eBooks with only a loose network of
volunteer support.
Project Gutenberg™ eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.
Most people start at our website which has the main PG search
facility: www.gutenberg.org.
This website includes information about Project Gutenberg™,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how
to subscribe to our email newsletter to hear about new eBooks.
Welcome to our website – the perfect destination for book lovers and
knowledge seekers. We believe that every book holds a new world,
offering opportunities for learning, discovery, and personal growth.

    Foreword The battle tosustain and increase corporate profitability grows ever more arduous in most sectors of the economy. Margins are caught in a pincer movement by, on the one hand, the steady improvement in competition and, on the other, the increasing awareness of customers. Things are ever changing. Now we see more businesses moving into the e-world. This has provided major opportunities to increase business, but comes at a price. From aware customers comes the demand for lower prices; a share of the lower costs assumed to come from doing e-business. There is no room for complacency. We need to grasp every opportunity not only to be ever more effective at what we do, but also to be truly competitive, winning more market share of the customers both nationally and globally. For success, a full understanding of costs and cost structures is necessary. Conventional account- ing and management reporting throw little light on the real cost dynamics in a business. As a result we are not in control of profitability at a level of detail that supports substantive decision-making. Activity Based Management (ABM) is an approach that has now come of age. ABM is not a technique; it is about management. ABM needs to be understood and implemented by all functions so its power can be unleashed and the benefits obtained. Over time, ABM has evolved considerably and is now being applied in manu- facturing, service companies, utilities, logistics, telecommunications, government bodies and many other sectors. With ABM, businesses can make dramatic improvements in measuring product and process costs, and more importantly customer profitability. Brian Plowman has created a reader-friendly, comprehensive narrative covering the key aspects of the theory and practice of ABM. Executives and managers in all functions in all types of organizations, as well as students, will appreciate this book’s practical and down-to-earth approach with many practical illustrations drawn from experience. xv Foreword 9/24/01 3:02 PM Page xv
  • 20.
    As well asstep-by-step guidance on basic principles, comparisons with tradi- tional methods, definitions of processes, activities, cost-drivers, data collection techniques and implementation steps, this book uses numerous detailed examples drawn from practice to build a logical picture of how to obtain the benefits of ABM. On its own, ABM help will change management decision-making. By under- standing how ABM also supports other profit improvement initiatives such as Business Process Reengineering, Shareholder Value Added and Customer Relationship Management, managers will learn how they can have the best possible toolkit to help put the business firmly on the road to leaps in profitability. This book should be required reading for anyone within an organization who has the responsibility to grow their business profitably.

    1 Introduction CUSTOMERS We knowthat customers are important to us. But even when we achieve the right orientation towards customers, we know, instinctively, that some customers are more profitable than others. We also know that some are probably loss-making. For some businesses, this doesn’t matter much. If margins are good enough, for whatever reason (a captive market, or a patent, or regulatory protection, and so on), overall profitability is sufficient. But few businesses have that luxury. We may also have some idea of which customers are the least profitable, and which are the most profitable. A walk around the business listening to anecdotes in different departments will tell us which customers are demanding of time and effort and cost: these are the customers who order unpredictably, amend their orders, change specifications at the last minute, delay payment, require special deliveries, and so on. Every department will have its own, separate experiences of customer behaviour. Nobody will have the whole picture. So anecdotal evidence will pick up the extremes – the ‘worst’ and the ‘best’ customers. What about the others? Customer profitability is a black hole in most managers’ understanding of their business. Identifying customer revenue is easy: it’s shown in the sales ledger. Identifying what individual customers cost – so we can understand whether or not they are profitable – is difficult. In a world in which competition, and often regula- tion, put increasing pressure on margins, it is vital to understand both product and customer profitability. As if competition were not enough to put pressure on margins, electronic commerce (e-commerce) promises lower unit costs and creates customer expec- tations of lower prices. 1 Chapter 01 9/24/01 3:03 PM Page 1

    THE TWENTY-FIRST CENTURYIS ELECTRONIC Technology advances, rapidly. Now companies can record and process all avail- able facts about their customers, logging their every purchase and preference, storing details of each transaction and interaction – be it through call-centre, e-mail or post. If customers visit a Web site, a company can know their every key- stroke and click. And it is possible to analyse the information to death. If the marketeers have got it right, they can predict customers’ every need and antici- pate their every whim. Web routings, pages and menus can be programmed to reflect the history of the customer and the actions taken on-line. Just like good salespeople, but at a fraction of the cost, they can package and price offers not to target a niche, but an individual. Welcome to the world of one-to-one marketing. Buying decisions become quicker and easier because customers are proposi- tioned only with what they find attractive, in a process they judge convenient, safe and painless. Soon customers will have forgotten how on earth they managed in the scrum of mass marketing when they had to do the donkey work. And on top of all this, sales costs plummet as the need for expensive salespeople and high street outlets, and for slow-turning showroom stock, disappears. It is enough to make a chief executive salivate. So where’s the catch? In fact there are two. The first is that all the competitors will be doing the same thing. Unless a company can take an early lead and then defend its additional market share, or unless the concoction of technology and marketing in this brave new world increases the size of the total market, the only hope is to do it better than the competitors – which is what organizations try to do every day. The second catch is that all the hyperbole about e-commerce usually has a special message to the customer. It says ‘lower prices’. After all, why do we put up with the DIY purgatory of supermarket shopping if it isn’t for cheaper groceries? Instead of being able to pass on to the customer the cost of all the expensive technical wizardry, companies will find that margins are squeezed even more! So is electronic commerce merely a development in which companies are forced to participate as a defensive measure, to the benefit only of customers and systems suppliers? Not necessarily. THE MISSING DIMENSION Customer Relationship Management (CRM) is aimed at capturing information that will allow companies to create the circumstances in which customers will buy. It maximizes the attractiveness of the offer and the convenience of the sale by matching the selling process to the customer. But in making the match, it risks driving hidden costs into the business, be it by shortening delivery lead times, by ACTIVITY BASED MANAGEMENT 2 Chapter 01 9/24/01 3:03 PM Page 2

    encouraging complex productvariants, by offering high levels of personal service, or by attracting customers who trigger excessive costs. It’s as if CRM provides a more extravagant, indulgent courtship display, but pays no attention to the slog of making the marriage work in the long term. It is not enough for companies to use CRM to anticipate every interaction the customer might have with the business, before, during and after the sale. They must understand the costs driven by those interactions. When the dust has settled on the expensive new e-commerce implementation and its bewildering array of ‘bundled’ products and services, customer profitability becomes the missing dimension, hidden deep in the business. Understanding all the costs that are driven by customer behaviours, some of them maddeningly cryptic, is vital to designing the processes and setting the prices that companies offer. Otherwise, they risk making customer promises they cannot profitably fulfil. CAN ALL CUSTOMERS BE KINGS? Not all customers are created equal in the sight of the supplier. They behave differ- ently from one another and have a variety of characteristics, so they generate different costs and margins. Some are highly profitable, others are spectacularly unprofitable, and many lie in between. Often, a small, anonymous group of customers contributes the major share of profits, while an equally invisible seg- ment erodes it. A clear understanding of customer profitability allows a business to differentiate the level of service it provides to various customer segments according to their needs and their value to the company. For example, it may offer individual atten- tion to prized customers in the form of dedicated telephone lines, free delivery, incentive pricing or customized products. At the same time, it might choose to reduce service to unprofitable customers – or to increase prices – even at the risk of losing them. A comprehensive view of the costs that customers drive allows a business to refine its processes and policies and focus its resources where they will have the greatest effect on profits: cementing customer relationships; avoid- ing excessive costs; matching prices to the service given. In many sectors, the customer continues to provide revenue and to drive costs well after the initial sale, through after-sales service, repeat purchasing or general administration. All these costs, as well as the revenues, need to be identified and analysed to ensure that the initial terms are profitable and that the customer segments a company targets have a high probability of being profitable over the lifetime of the relationship. An added benefit of customer profitability analysis is that it highlights the costs of poorly designed internal processes. As the true costs of processes emerge, INTRODUCTION 3 Chapter 01 9/24/01 3:03 PM Page 3

    managers can sensewhich costs are suspiciously high. This triggers a cycle of further investigation, problem identification and process improvement, thereby correcting profit-harming defects that would otherwise continue undetected. ACTIVITY BASED MANAGEMENT Activity Based Management (ABM) enables managers to understand product and customer profitability, the cost of business processes, and how to improve them. Since conventional management accounts and standard costing systems do not provide this information, it is perhaps surprising that ABM is not more widely used. Unlike many management techniques, research shows that 80 per cent of companies that have employed activity-based techniques found them to be successful. Why? Activities consume resources – people, materials and equipment – and this consumption can be measured. Activities are triggered by events, which can be counted, or decisions, which can be reviewed. Activities produce outputs – products and services, which can be counted and measured. Activities can be undertaken by different methods, which will vary the unit cost. Activities are linked together to form business processes. Understanding what activities are, what they cost, what drives them, what they produce, how they are done and how they are linked together is useful. We have understood manufacturing activities in this way for years. We measure the consumption of direct labour and materials in making products. On average, however, direct labour, materials and components account for around two-thirds of total costs in manufacturing businesses. The other, unmeasured, third is over- head activities and costs. In service industries, the ratio is the other way round – the unmeasured ‘overhead’ accounts for two-thirds or more of costs. Overhead costs are the black hole in conventional management information systems. ABM shines light into the hole. Knowledge of a business at the level of activities is the basic building block upon which new understanding can be built of where profits are being made and where they are being eroded. By making visible what was previously invisible, ABM throws a spotlight on those aspects of a business where action can directly improve business perfor- mance. Because it deals with ‘financial numbers’, ABM is often seen as the pre- serve of the Finance function. In fact, its real strength lies in providing genuinely useful information for all functions in an organization. Managers throughout the business need the right information to understand and address two key issues: ● how the company can position itself better in the market – for which accurate product and customer profitability information is vital ACTIVITY BASED MANAGEMENT 4 Chapter 01 9/24/01 3:03 PM Page 4
  • 25.
    ● how itcan improve its internal capability and lower unit costs – for this, it needs to understand and change the procedures, systems and processes that create products and deliver services to customers. Most organizations are complex. Building an ABM model of a business requires a structured approach and the dedication of a team to achieve a result in a reason- able timescale. But building a model is only the start. Embedding ABM into the business means giving managers not only a new understanding of what drives costs, but the means to measure and act on the drivers to reverse adverse trends. ABM is about management. This book is intended for ‘general management’ in any type of organization. The following chapters discuss the basic principles of the approach, describe how to approach the development of ABM models and the implementation of ABM thinking in a business, and use numerous case studies to illustrate how ABM can make a difference to business performance. KEY POINTS ● We know customers are important but without knowing the costs that customers impose on us, we’ll never know which ones are profitable. ● When we know the costs that are driven by customer behaviours, we can differ- entiate the level of service we provide to various customer segments. ● In manufacturing businesses, direct labour, materials and components account for around two-thirds of total costs. The other, unmeasured, third is overhead activities and costs. In service industries, the unmeasured ‘overhead’ accounts for two-thirds or more of costs. ● ABM helps companies position themselves more advantageously in the market by providing accurate product and customer profitability information. ● ABM helps companies to improve their internal capability and lower unit costs. ● ABM is often seen as the preserve of the Finance function. In fact, its real strength lies in providing genuinely useful information for all functions in an organization. ● E-commerce channels currently give certain companies cost advantages. But not for long. Competitors will soon be doing the same thing. ● In e-commerce, customers want a share of lower costs, reflected in lower prices. In the future, it will be even more important to know customer profitability. INTRODUCTION 5 Chapter 01 9/24/01 3:03 PM Page 5

    2 Historical perspective THEFIRST SERIOUS QUESTIONS In the late 1980s and throughout the 1990s, the relevance of traditional accounting practices was seriously questioned. Conventional costing, budgeting and manage- ment accounts became ever less able to support the business decisions that were now relevant. The relevance debate was founded on three key criticisms. The first criticism was levelled at the lack of technical developments in manage- ment accounting practice despite major changes in manufacturing technology. These major changes had resulted in greatly increased productivity, flexibility and quality, together with reduced lead times and inventory. Further, the significant changes in the proportions of ‘direct’ costs to ‘overheads’ had created major distor- tions in calculating product costs based on simplistic overhead recovery rates. The second criticism held that management accounting was nothing more than financial reporting, leading to information that was too distorted, too aggregated and too late to be of much value to management. The final criticism was concerned with the history of management accounting. A mature management accounting tradition was well established in the 1920s. In those days, traditional accounting had served business needs well in terms of cost management, management controls and performance measurement. However, the worldwide dominance of accountancy practice, standard training and examina- tions means that significant inertia towards change still exists. The relevance discussions were published during a period of concerns over America’s need to regenerate its industry in the context of the emergent global economy and the lessons from the success of Japan at that time. The moves in management accountancy were towards cost management and away from cost accounting. Developments since have included a concern with understanding such aspects as value-adding processes, life cycle costing, market-driven target costing, product and customer profitability, customer relationship management, Shareholder Value Added and the emergence of e-commerce. 9 Chapter 02 9/24/01 3:04 PM Page 9

    NEW COSTING APPROACHESGATHER PACE Costs have been addressed in many ways in businesses, although traditional prac- tice had formed around the major manufacturing sectors. The key problems with trying to determine accurate product costs started to gain the attention of a body called CAM-I (Consortium for Advanced Manufacturing – International). This body researches all aspects of the manufacturing sector in its struggle to come to terms with the changes that modern methods have introduced. The CAM-I Cost Management Systems (CMS) Program is internationally recognized as a leading forum for the advancement of cost and resource manage- ment practices. Organized in 1986 as a coalition of leading thinkers from industry, government and academia, the CMS Program has accomplished extensive research and development of new management methods. The CMS Program is acknowledged worldwide for raising the awareness of Activity Based Costing (ABC) and Activity Based Management. Although the manufacturing sector was the first to find that traditional account- ing had lost its relevance, the service sector began to catch up. In financial services, what is a direct cost, and what is an overhead? Tracking the real cost of its products, services and customers became an issue as the recession and severe competition started to erode the traditional safe profits in banks and insurance companies. In the utilities sector, the problem had grown rapidly with the changes in legis- lation that created greater competition. The ‘regulator’, who wanted to ensure visibility in a company’s costs and put constant downward pressure on prices, further complicated the situation. Where there are virtual monopoly suppliers of services, the UK Monopolies and Mergers Commission is keen to gain access to the real costs of providing products and services, and handling customers. Another perspective is through the value chain. The term Efficient Consumer Response (ECR) has been coined to encapsulate improving the chain that stretches from the basic raw material sources of a business through to the ultimate consumer. Generally, firms are only involved in part of the overall chain of value- creating activities, and therefore must endeavour to develop information that permits internal cost management and allows information to cross the company’s boundaries. Activity-based approaches form the foundation on which information and costs are analysed throughout the value chain. The new millennium has brought the prospect of a new dawn to many busi- nesses. But all types of companies are finding that they are still in the dark. Their traditional accounting and costing methods remain unable to provide the answers to very relevant business questions, such as: PART I: THE CONTEXT 10 Chapter 02 9/24/01 3:04 PM Page 10
  • 31.
    ● How dowe measure commercial success? ● Which parts of our process add value, or not? ● Do we make profitable products, and provide profitable services? ● Which is our most profitable customer? ● What can we afford to negotiate away? ● Which type of distributor is important to us? ● Do some products subsidize others, and if so, by how much? ● Are some of our customers targets for our competitors? ● Are we going for volume at the expense of profits? ● What is the real contribution from our product range? ● How should we invest this contribution from our current products? ● Should we go for new products or new markets? ● Will our new e-commerce channel provide the profits we yearn for? Most of these questions have always been asked. It is management’s job to answer them. But while struggling to feed ever more irrelevant budgeting systems and answer monthly management accounts variance queries, management has had to fall back on ‘gut feel’. This is a poor substitute for appropriate information. ABM fills the chasm so long filled with inappropriate information. KEY POINTS ● The relevance of traditional accounting practices has been seriously ques- tioned. Criticisms concern the distortions in calculating product costs based on simplistic overhead recovery rates, financial reporting that is too distorted to be of much value to management, and the worldwide dominance of accoun- tancy practice, standard training and examinations, creating a significant inertia towards change. ● The foundations of ABM were built on the manufacturing sector, but the service sector has rapidly caught up, driven by regulatory and competitive pressures. ● Activity-based approaches form the foundation on which information and costs are analysed throughout the value chain. ● Traditional accounting and costing methods remain unable to provide the answers to very relevant business questions. ABM has filled the gap. HISTORICAL PERSPECTIVE 11 Chapter 02 9/24/01 3:04 PM Page 11

    3 What isABM? Initially, Activity Based Costing (ABC) was presented as a means of establishing product costs more accurately. The emergence of Activity Based Management (ABM) provided a means of enhancing profitability. ABM is underpinned by a theory of resource consumption, with activities viewed as giving rise to costs, as in ABC, but taking the analysis further in a way that provides management with insights into managing the business overall. Essentially, these insights are focused on a process view of the business and a deeper understanding of product, channel and customer profitability. COSTING AND PROFITABILITY The ledger, budgeting and monthly management accounts are based on reporting resources: those planned to be used, the consumption month on month and the variances from plan. Resources are those things that provide the means to allow work to be done in the organization: salary costs for the people doing the work, accommodation costs so that people can work in buildings, utilities so that people can see what they are doing and keep warm, vehicles so that goods can be delivered and customers visited. In some cases, the list of types of resource on the ledger may seem endless. But no matter how long the list of resources, nothing in the ledger or the man- agement accounts tells us how the resources are being consumed in doing things, to what purpose, or in what way. Resources are consumed by activities and it is at this level of analysis that we see what is actually being done. At this level we can also take a view on whether the activities that are being performed are necessary. We can also find out whether the activities are being done well and use the best methods, and so take the business forward, or whether they are really only sorting out problems that are dragging the business back. 13 Chapter 03 9/24/01 3:05 PM Page 13

    Activities are undertakenfor many purposes. Some directly manufacture prod- ucts, while others indirectly support manufacture, such as the Quality department or materials handling. Some activities support the business as a whole, such as recruitment and training or the parts of the IT department that keep the network running. Other activities are directly associated with customers, such as the salesforce, or more indirectly within the Credit Control department. Other parts of the busi- ness are working on activities to create a better future, such as New Product Development, and others are working on influencing potential customers, such as Marketing and Advertising. Some parts of the business have little to do with products, services or customers but are necessary to keep the business legal, such as statutory reporting or orga- nizing the shareholders’ annual general meeting or preparing for the annual audit. Activities are the very engine at the heart of the organization. Understanding what is done, how it is done, what causes it to be done and why we are doing it gives us a better chance of deciding whether we are getting the best value from the resources we deploy. As a simple analogy, budgeting and reporting on the differ- ent amount of food we eat may be mildly interesting but what people then do with their time having consumed the resources is what influences the world around them, for better or worse. In conventional accounting, and particularly in manufacturing companies, costs are categorized into two main types: direct costs and overheads. Direct costs include the employees manufacturing the products, and the raw material they use. Overheads are the rest. The problem then arises when the costs of the products need to be calculated. Although we will look at this in greater detail in later chapters, we can say at this point that an ABM analysis accurately assigns the costs of those overheads that are actually influenced by the products being made or the services being provided. Having derived accurate product costs, ABM goes further and analyses the costs of servicing each customer or specific segments of the customer base. Customers create a wide range of differing costs for a host of reasons. The key insight that ABM exposes arises when revenue is brought into the equation. When the actual costs of the products or services going to a particular customer are calculated and the actual costs of servicing that customer derived, we can compare these figures to the revenue from the customer, as shown in Figure 3.1. Revenue minus the product costs gives the ABM Product Contribution. Revenue minus the product costs minus the costs of servicing the customer gives the ABM Customer Contribution. The sum of all the customer contributions has to pay for all those remaining costs that are not associated with the current products or customers, such as new product development and statutory accounting. Anything left after that is the profit. PART I: THE CONTEXT 14 Chapter 03 9/24/01 3:05 PM Page 14

    It is atthe level of ABM Product or Customer Contribution that we use the term ‘Product and Customer Profitability’, as it is at this level that meaningful compar- isons can be made between products and between customers. It is this type of analysis that exposes small or negative values prompting a serious review of which products or customers to keep, or at least a decision to take action to try to turn the relationship into one that provides positive contributions. We will look at this later in greater detail, as this insight into a company’s costs is the central advantage of using ABM analysis. By understanding how costs relate to those factors that drive the costs, we can use the powerful approach of Activity Based Budgeting (ABB). Rather than a futile circular argument revolving around resources, such as just asking for more people, the debate focuses on the drivers of cost that influence how much activity is actually required. ABB analyses the products or services to be produced, and so determines the level of the activities required. The level of activities then deter- mines the resources to be budgeted. When automated, ABB can rapidly and accurately produce financial plans and models based on varying levels of volume assumptions. The more obvious volume assumptions would take into account levels of WHAT IS ABM? 15 Figure 3.1 ABM Product and Customer Contributions Sales revenue Manufacture indirect Direct materials Direct labour Other manufacture overheads ABM Product Contribution Direct materials Direct labour Gross margin Manufacture indirect Direct materials Direct labour Other manufacture overheads ABM Customer Contribution Customer- related overheads Chapter 03 9/24/01 3:05 PM Page 15

    product or servicebeing provided. More subtle assumptions would take into account, say, the projected numbers of staff to be recruited, and hence the impacts back into the personnel and human resources activities, and thus resources. From the customer perspective, providing more volume of the same products to the same customers would have one set of impacts on activities. In another scenario, additional new customers placing orders for half the previous average quantity per order line but for an average of double the number of order lines per order would have a quite different impact on activities, and thus overall resources, in various functions. This is the stuff of the real world, where real things are happening. Sitting in a functional silo with no knowledge of what actually drives the costs in a function makes guessing the resources required for the next twelve months one of the most futile exercises that has ever been invented. This probably accounts for the long, sad faces when the budget round is announced. Using activity-based target costs throughout the product design and develop- ment process brings the real world of the competitive marketplace right into the start of the process that creates costs. Gone are the days when companies could design a product, work out its costs, add a bit for overheads, then announce the price. To grab market share and ensure sustainable growth, a company has to know beforehand the price that will ensure the product’s success. At the design and development stage, more than just the direct costs are designed in. At this stage, the company has to think through all aspects of the processes in the busi- ness affected by the product or service so that it does not breach the target cost. PROCESS IMPROVEMENT An organization is a series of activities that combine in processes to create valu- able products or services for customers. It is the effectiveness of an organization in performing these processes – to create high value at low cost – which marks out a successful company. Most of a company’s significant processes travel across func- tional boundaries, and it is at these boundaries that delays and quality problems occur. ABM focuses on the company’s processes. If the processes are understood then failure activities can be eliminated from those processes. Value-adding activities can be examined to see whether better methods can be used. Time delays and quality issues can be addressed at the point in the process where they occur. ABM is the management of improvement through the analysis of business processes, and their associated activities. This analysis is carried out systematically and cross-functionally so that improvement projects can be readily implemented and the changes monitored. ABM is an approach that involves many people within the organization, and is: PART I: THE CONTEXT 16 Chapter 03 9/24/01 3:05 PM Page 16
  • 37.
    ● a vehiclefor creating process improvement – both incremental, continuous improvement and radical restructuring of the organization ● a model to show how costs (and revenues) are created through processes and activities – if you understand the activities, then you can understand the costs; if you understand the processes, then you understand the business ● a means of measuring the company’s progress in the key areas of the business that need change and improvement. We will look at this use of ABM in greater detail later, as the insights gained from process analysis are central to reducing unit costs, eliminating waste and improv- ing levels of service to customers. Although ABM can be used to address a specific project or process that needs improvement, it is at its most effective when the company uses ABM as a standard approach to business improvement. This way, the entire organization can be involved in process improvement, and over time every process within the com- pany can be studied, and changes initiated. KEY POINTS ● Nothing in the ledger or the management accounts tells us how resources are being consumed in doing things, to what purpose, or in what way. ● Activity analysis allows us to find out whether the activities are being done well and use the best methods to take the business forward, or whether they are really only sorting out problems that are dragging the business back. ● Revenue minus the total product costs gives the ABM Product Contribution.

    Frameworks for measurement 4and improvement Although ABM can be used as a stand-alone approach to understand processes, product and customer costs and profitability, it provides a more powerful means of decision support if it exists as part of a larger framework of measures. Over the years, a number of frameworks have been developed, each endeavour- ing to arrive at a more rounded perspective on the business and a reduced empha- sis on the previous domination of financial measures. Although traditionally profit has assumed the dominant role as a measure, the many means of its attainment are recognized as being much more varied and com- plex to measure and control. Consequently, as well as being concerned with sales and margins, it is necessary to have information on such things as production times, component commonality, quality initiatives, customer satisfaction, cus- tomer service activity, employee skill development, employee turnover, legislation changes, environmental impacts and many other variables in the business. In fact, any element of performance can be important if it is related to success in the marketplace. Their integration has been more formally recognized by the use of a number of frameworks that attempt to bring a more rational balance to the variety of measures used in the business. ABM is a key component of these measurement frameworks. THE BALANCED SCORECARD Professors Kaplan and Norton first described the Balanced Scorecard in an article in the Harvard Business Review in 1992. The term ‘balanced’ reflects the objective of reporting to stakeholders other than the owners of the business, as well as in ways quite different to financial reporting. The Balanced Scorecard includes four perspectives, as shown in Figure 4.1. As well as the more traditional measures found in the financial perspective, the scorecard includes customer, internal business, and learning perspectives. 19 Chapter 04 9/24/01 3:06 PM Page 19
  • 40.
    The customer perspectivecan include measures of quality, lead times, reliability and customer service as these impact on customer satisfaction, repeat business and referrals. The internal business perspective is concerned with processes and productivity. Crucially, there is a recognition that the workforce is a vital stake- holder whose skills and commitment to the organization cannot be taken for granted. The fourth perspective, that of learning and innovation, is concerned with performance improvements and the ability to introduce successful new products and services. All four perspectives reflect the need to sustain a strategic position in the marketplace to create value for shareholders, provide challenging employ- ment opportunities for the workforce and enjoy a sustained partnership with customers, both corporate and consumers. It is therefore imperative that an appropriate range of measures exists to integrate in the scorecard. A by-product of using a Balanced Scorecard is that, throughout the organization, it raises the awareness of measures, in a language that people can understand in their own areas of responsibility and influence. However, where useful informa- tion is lacking, ABM becomes a powerful tool to understand and answer funda- mental questions that arise around processes, products and customers. Profitable customers served by ineffective processes will not lead to success. Impeccable processes serving unprofitable customer segments will also drag the company down. If employees focus their learning and innovation on products and services PART I: THE CONTEXT 20 Financial Internal Innovation & learning Customer On course Change course!

    that attract disproportionatelyhigh but largely invisible costs, it can bring a busi- ness to its knees. The Balanced Scorecard by itself is not a guarantee of corporate success. The underlying behaviour of costs and an understanding of what drives costs provide the knowledge and insights to drive improvements. In this respect, ABM is a fundamental building block. THE BUSINESS EXCELLENCE MODEL The European Foundation for Quality Management (EFQM) Business Excellence Model arose during the time that ‘quality’ and ‘total quality’ had ascended to the highest point of management’s consciousness. The quality movement had tended to follow the course of ISO 9000, an international standard that focuses on quality systems within the business. In response to this trend, a number of companies leading the quality movement searched for a means of describing a business across a range of features that went beyond just looking at the internal quality systems. This endeavour led to the formation of the EFQM and the publication of the Business Excellence Model. The model defines nine elements as shown in Figure 4.2. Five elements are known as enablers, and the remaining four are the results. Each element has a weighting, and when taken as a score, a company with a total of 80 per cent or more is recognized as achieving excellence. In Europe, such high scores put a company in the running for the annual European Quality Awards. Interestingly, a company that states that it has implemented ABM as an approach to inform and change its scoring on a number of elements only achieves an enhanced score if it actually produces the ABM information and acts on it.

    Setting up anABM programme but failing to apply its findings will count against a company. SHAREHOLDER VALUE ADDED The measure of Shareholder Value Added (SVA) is unashamedly financial. SVA, the generic term (also known as Economic Value Added), was introduced as a measure by the American consulting firm Stern Stewart & Co. Their term and the three-letter acronym, EVA are both trademarks of their company. The definition is simply: Shareholder Value Added equals the net operating profit after tax minus the capital charge. The net operating profit after tax brings into focus prices, volumes, the cost of sales and all the operating expenses in the business, as well as taxes. It is therefore imperative that the business knows which products and customers are profitable, and why, and that its processes operate at the lowest unit cost. Whatever tech- niques or approaches are used to achieve these ends, it is important that informa- tion in the business is structured to support the right decision-making. ABM is a building block to create this knowledge. The capital charge is all capital (net working capital plus net fixed capital) multi- plied by the cost of capital. Capital comprises working capital (debtors, creditors and inventory) plus fixed capital (property, plant and equipment). Actions to reduce debtor days and work in progress would be simple examples of increasing the value in the business. Investing in capital equipment focused on profitable products to profitable customers requires greater finesse in ensuring that the right decisions are made. All financial measures, including SVA, tell us the outcome of many different things, but they usually hide the causes of good or bad profitability. The good or bad performance of individual processes is seldom visible in financial performance measures, and the real profitability of products and customers is completely obscured. Depending on the type of business, actions to increase value will differ. Inside an SVA measurement framework, ABM is the means to actually influence the value drivers in the business. It is this knowledge that makes a difference so that people can make decisions and take actions to increase value. POSITIONING AND CAPABILITY The collection of measures encapsulated within the term ‘positioning and capability’ was developed by the UK consulting firm Develin & Partners, and is PART I: THE CONTEXT 22 Chapter 04 9/24/01 3:06 PM Page 22

    founded on theprinciple that organizations need to make a series of steps from where they are now to some future goal. To guide the company on its journey to a future goal, a ‘map’ is required, where the axes of the map are positioning and capability. The basic map is shown in Figure 4.3. Positioning is to do with external factors, such as: ● understanding customer needs ● understanding product and customer profitability ● understanding competitor initiatives ● determining the business’s financial needs ● complying with changing legislation ● meeting environmental constraints. Getting positioning right leads to higher levels of revenue through providing prof- itable products and services, increasing market share, increasing the size of the market, and by retaining profitable customers. Capability is to do with internal factors, such as: ● key business processes ● procedures and systems ● competencies, skills, education and training ● attitudes, style and behaviours.

  • 44.
    The capability ischanged to deliver the desired positioning. Capability creates the costs in the business. The journey joins revenue and cost. Getting the balance right between positioning and capability enhances profits and the value of the busi- ness. ABM is the vehicle by which companies journey along their chosen route. ABM informs key aspects of positioning, particularly when used to provide accurate product costing and to derive product and customer profitability. ABM informs key aspects of capability, particularly when used to understand process costs, fail- ures within processes, and to establish the link between costs and the drivers of cost. ABM provides the basis for management to make better informed decisions, both on positioning and capability. In other words, the company can determine which products, markets and customer segments it wishes to retain, it can make relative pricing decisions based on competitor initiatives, and it will be able to focus on those aspects of capability which leverage profitability through process improvement and a reduction in unit costs. Using ABM during the positioning work provides an opportunity to undertake customer engineering as an action to guide changes in capability. Avoiding a cer- tain activity may then be an initial action, rather than spending effort on improving what could be an unnecessary process. ABM analysis of the current business, prior to making changes to any processes, can answer a number of positioning questions: ● Can the salesforce be directed towards more profitable segments in relation to the costs of servicing the business that is generated? ● Will a switch away from volume selling to focused selling improve short-term profitability? ● Can some customers or product lines be dropped and achieve an increase in company profitability? ● Can we apply discounts more effectively to achieve volume and know that we will remain profitable? ● Can we switch some customers to wholesalers or other third parties, rather than service every customer ourselves? ABM is the way to link a company’s trading relationships (positioning) to its internal cost structure (capability). The basic premise is that activities consume resources and convert them into products and services to customers. Costs are therefore the consequence of resource decisions, and income is the consequence of linked activities, the business processes. The requirement is therefore to improve resourcing decisions as the means of managing costs, and to improve processes as the means of improving business effectiveness and thus customer service and revenue. 24 PART I: THE CONTEXT Chapter 04 9/24/01 3:06 PM Page 24

    In the positioningand capability framework, ABM plays a key role in informing the journey. On the positioning axis, ABM is used for profitability management, such as costing and profitability analysis, customer and product mix decisions, and support for marketing decisions. On the capability axis, ABM is used for resource and performance management, such as resource and service level changes, activity-based budgeting and cost driver analysis, and for process improvement to eliminate process failures and reduce unit costs. KEY POINTS ● The integration of many elements of performance has been more formally recognized by the use of a number of frameworks that attempt to bring a more rational balance to the variety of measures used in the business. ABM is a key component of these measurement frameworks. ● The Balanced Scorecard includes four perspectives: financial, customer, internal business, and learning.

ABM is the means to influence the value drivers in the business that will help increase SVA. ● Positioning is to do with external factors, and getting this right leads to higher levels of revenue through providing profitable products and services, increas- ing market share, increasing the size of the market, and by retaining profitable customers. ● Capability is to do with internal factors, a change to which delivers the desired positioning. Capability creates the costs in the business. Positioning and capa- bility thus join revenue and cost. Getting the balance right enhances profits and the value of the business. ● The journey of change can be mapped using the two axes of positioning and capability. ABM provides the information for both axes, to plan the journey and measure how far you have travelled. FRAMEWORKS FOR MEASUREMENT AND IMPROVEMENT 25 Chapter 04 9/24/01 3:06 PM Page 25

    5 The ABMframework In Chapter 4, we saw how ABM fits into a number of overarching frameworks of measurement and improvement. In Chapter 6, we will see how ABM is used in a real-life example, to illustrate how ABM handles costs, assigning them to activities then onwards to products, channels and customers. However, before going into an example it is wise to take a few moments to describe how ABM views the treatment of costs, which differentiates it from tradi- tional accounting approaches. This chapter explains the way ABM handles costs and the characteristics of activities compared to conventional approaches, as well as introducing the language of ABM. TRADITIONAL RESOURCE ACCOUNTING Most established accounting systems usually capture and distribute resource costs based on one or more of the following methods: 1. organization structure or cost centre accounting 2. budgetary accounting 3. cost allocation accounting. From their longevity of practice, we must assume that in the past they have met the needs of organizations to some degree. Yet every one of them fails to meet the full requirement for management information that will adequately support decision-making in today’s competitive environment. COST CENTRE ACCOUNTING This is a popular method for applying resource costs to an organization. The accounting system identifies each of the organizational parts of the traditional functional structure and applies the identifiable costs to that part of the structure. 27 Chapter 05 9/24/01 3:07 PM Page 27

    In many traditionalorganizations, the only costs that are identified to the organiza- tion’s functional departments are the salary costs. Although overhead costs are sometimes distributed to cost centres, it is more common to find that these costs are ignored at the unit level. Many overhead costs are held centrally by the providers of services, and not sub-divided to the users of the services. For exam- ple, the cost of ‘vehicles’ would be held in the function or department that looks after the vehicles. The cost of ‘postage’ would be held in the postroom where the mailing physically takes place. This system was created to provide management with some information on the costs of the organization’s departments. Some argued at the time that this would make ‘controllable’ costs visible to those managers that have to control the costs. However, under cost pressure the owners of resources supplied to others would turn the tap down or off. The Stationery department refusing to issue paper for other departments’ photocopiers is a result of this approach to cost control. Where attempts to obtain a true picture of departmental costs are applied, man- agers of resources that are supplied to others apply cross-charges to users, based on a rate for the service. The rate is based on a collection of costs the service department actually incurs, such as its own staff salaries, to which it adds a mysterious amount to cover its own overheads and the costs that it has received as cross-charges from others. The cross-charging game can reach heights of absur- dity when internal sub-divisions of the organization are made into profit centres. The charge-out rate then includes a bit extra, which it calls ‘profit’. In some instances, this accumulating figure is then used to purchase something from out- side on the basis that it is using spare income, and not a departmental cost. From the organization’s perspective, this is real money going out the door. However, trying to get accurate costs to the place in the organization where the budget for the funds is held can also create absurd situations, as the following example aptly illustrates. CASE STUDY A company introduced a simple method to improve the cost-effectiveness of the use of taxis. By arranging to use a single supplier, any travellers only had to print and sign their name against the meter cost recorded on the taxi’s log sheet. To prevent fraud, the passenger retained a tear-off copy slip showing the cost. On a monthly basis, the taxi company presented its itemized bill, which a clerk in Accounts dutifully used to look up where each passenger worked. The cost centre manager’s name and cost centre number were also looked up and noted. The annotated invoice then started its journey around the site for each manager to authorize and add the cost centre allocation number for taxi PART I: THE CONTEXT 28 Chapter 05 9/24/01 3:07 PM Page 28

    journeys to theinvoice. Later, these costs would be accumulated and reported to each cost centre manager. Three months later, the irate taxi company would begin to demand payment. The problem for the Accounts department was knowing where the invoice was in its journey around the site. In a year, 40 per cent of the invoices never found their way back to the Finance function. The taxi company would regularly threaten court action to secure payment. Accounts Payable would just ask for a faxed copy of the invoice and pay the same day on receipt of the fax. Finally, someone did question whether the whole process added any value, or whether it just added unnecessary cost. In all this striving for accuracy, accountability and control, hardly any real attempt is ever made to trace costs to the activities or process flows in organizations or to the ultimate output, the products and services for customers. BUDGETARY ACCOUNTING The tracking of costs to a budgetary account is often combined with cost centre accounting. In this case, the major concern of the spenders of resources is to ensure that their total expenditures do not exceed the allocated budgetary amounts. Consequently, accounting systems become a safeguard mechanism to capture commitments, undelivered orders, and expenditures, normally divided into the cost centres that reflect the organization structures, to enable tracking of actuals, budgets and variances. The measure of success, and thus the major objec- tive of each accountable manager, is to use the resources assigned fully, rather than enhancing productivity or reducing expenses. In some types of organization, any attempt to conserve resources or work more effectively to come under budget runs the risk of prompting a reduction in the future budget resource level. The budgetary control mechanism can reach heights of absurdity. CASE STUDY In a government research organization, the scientists received funds to under- take research projects. Towards the financial year end, the researchers had unspent funds, but there were insufficient hours of research capacity to conduct the research before the year end. The fund providers wanted the funds spent (for fear of their own funds for the following year being reduced), but were only concerned that the money was spent on ‘project-related’ costs. In this case, buy- ing equipment was acceptable. As specialist equipment would be pointless, the THE ABM FRAMEWORK 29 Chapter 05 9/24/01 3:07 PM Page 29

    researchers looked forsomething more generic. Two weeks later, three large vehicles arrived on site delivering top-of-the-range-desktop computers. As there was no immediate scientific purpose for the computers, they remained in their boxes and researchers used them as additional seats. Among the support departments, frustrations reached boiling point when they saw the vehicles being unloaded. The cap on their costs always prevented them procur- ing decent equipment. Worse was to come. Given the different funding regimes for the two groups, the overhead functions were not allowed to use the spare computers languishing in their boxes. Like cost centre accounting systems, budgetary control mechanisms make no attempt to cost the outputs of all the work, or in many cases to even bother to define the output. If real customers are at the end of a supply chain of activities in such environments, then their needs can be well down the list of priorities, with ‘meeting the budget’ firmly at the top. COST ALLOCATION ACCOUNTING Where an organization has the characteristics of a business then it generally has a need to distribute its costs to an output so that it can price its products or services. Revenues also come into the picture, and we talk about ‘revenues minus total cost leaves us the profit’. To make the costs visible, ‘true’ cost accounting systems were established to capture and distribute costs to the outputs, such as goods or ser- vices. These cost accounting systems use the classic model of cost distribution which was designed around the major sector of the economy at the time: manu- facturing. In this system, the focus of gathering costs and collecting them under generic headings relied upon the simple classifications of direct labour, direct materials, and overhead. Businesses and business-like organizations have relied upon the historical model of cost accounting for over a hundred years. However, the traditional cost accounting methodology does create significant inaccuracies in output costs because of the manner in which overhead costs are apportioned to output rather than assigned or traced to output. When this erroneous method of cost distribution finds its way into the ultimate price of the output, it leads to poor management decisions about which products or services to promote hard, or which to discontinue, and which customers it should sell to or drop. As traditional accounting has such a grip on most organizations, we would argue that it is in the areas of the fundamental flaws it contains that ABM really makes a difference. In particular, ABM is superior to traditional accounting in a number of ways: PART I: THE CONTEXT 30 Chapter 05 9/24/01 3:07 PM Page 30
  • 51.
    ● ABM providesvisibility in the way costs flow through the business. ● ABM establishes the links between activities and those factors, internal or external, that drive the level of activity up or down. ● ABM eliminates the false divide between direct costs and overheads. ● ABM separates out those costs that deal with today’s business from those that secure the future. ● ABM ignores gross margin and uses accurate product and customer contribu- tions as the basis for comparing product and customer profitability. ● ABM exchanges functional myopia for a cross-functional process view of the organization. ● ABM exchanges the stilted definitions of value-added and non-value-added for sensitive categories that highlight the subtle impact of internal process failures and external customer behaviour. ABM VERSUS TRADITIONAL TREATMENTS OF COSTS At many levels, ABM brings a different perspective to how costs are treated. ABM challenges the traditional approaches to product costing, gross margins, profit- ability, functions and hierarchies, value-added and non-value-added, and budget- ing. TRADITIONAL PRODUCT COSTING It is in the area of product costing that serious weaknesses in the traditional approach first became a cause for concern. In the days when traditional account- ing practices were being formed and internationalized, the dominant industries were in the manufacturing sector. In a typical large manufacturing company, there would be large numbers of employees concerned with direct manufacturing and a much smaller number in the overhead departments. In a situation where the direct labour costs could be as high as 90 per cent and overheads 10 per cent of total costs, it was important to achieve some accuracy in terms of the hours, and therefore costs, required to make components and assem- blies. Work-study and other techniques found a ready use in determining the direct labour content of any product. The direct material costs were also simple to calculate for each product, based on raw material content, scrap rates, bought-out parts and so on. Working out how much of the overhead activity was actually asso- ciated with each product was seen as a lot of effort for such a small improvement in the accuracy of the product cost. This led to the use of the Overhead Recovery Rate (ORR) as the fundamental method of product costing. To derive a method of calculating the proportion of overheads to allocate to each THE ABM FRAMEWORK 31 Chapter 05 9/24/01 3:07 PM Page 31
  • 52.
    product, a simpleratio was derived, known as the ORR. A company would simply find the overall ratio between total overhead costs and total direct labour, say 10 per cent. The direct labour for each product made, and any new ones developed, would then have 10 per cent added to account for the overhead, and so give the product cost. As manufacturing became more complex, the proportion of overhead activities to direct activities started to increase. Product costs now became far more sensi- tive to the indirect and overhead costs associated with each product. The tradi- tional ORR became highly suspect as a means of calculating product costs. Some products could be seriously under-costed, and thus probably highly competitive, but an increase in sales volume would actually erode profitability. Conversely, over-costed products would be unattractively priced, and few sales made. As the proportion of overhead costs increased in a business, the more serious the distortion in product costing became through using the ORR method. ABM PRODUCT COSTING In ABM, the indirect and overhead costs are determined for each product. The characteristics of two products can be quite different in the way they need over- head activity to support manufacture. CASE STUDY A company that had traditionally made its name manufacturing bogies for rail- way trucks and carriages had branched out into making braking systems for long-haul diesel road vehicles. While the technology surrounding the railway business had not developed significantly over the years, the road vehicle tech- nologies had advanced in complexity at a rapid rate. Using direct labour as the determinant of the proportion of overhead costs had led to over-priced railway products and under-priced road vehicle products. The growth in the road vehicle business then seriously eroded overall profits, and the stable rail business was drifting to competitors. Figure 5.1 shows two of the company’s products costed using the conven- tional ORR, in this case 300 per cent. For product Pr1, the direct labour had 50 units of cost, so the manufacturing overhead was assumed to be 300 per cent of this: 150 units of cost. Product Pr2 again used 300 per cent, and this was applied to the direct labour cost of 200 units, giving a manufacturing overhead of 600 units of cost. Using a conventional ORR took no account of the real differences in the amount of overheads that either product required. PART I: THE CONTEXT 32 Chapter 05 9/24/01 3:07 PM Page 32
  • 53.
    Product Pr1, aroad vehicle braking system, was complex, had many produc- tion changes, and used difficult manufacturing technology. There were also many discussions with specialist suppliers. Product Pr2, a railway truck bogie, used simple manufacturing technology, enjoyed a steady demand with few changes to schedules, and had used the same suppliers of raw material over a long period. Using the ABM approach, the direct and actual overhead costs reflected the real situation, as shown in Figure 5.2. Note that for Pr1 the conventional approach gave a contribution nearly double what it actually was. In other words, in reality the product was less profitable than they thought. Conversely, Pr2 was much more profitable than they thought. Using the overhead recovery approach meant that Pr1 was under-priced. They had orders, but made little profit. Sales of Pr2 could be higher if it wasn’t over-priced.

    TRADITIONAL VIEW OFGROSS MARGIN In traditional accounting, we find the term ‘gross margin’, defined as the revenue minus the direct costs. As long as the gross margin is a positive number, then the product is deemed to make a ‘contribution to overheads’. In other words, whatever the overheads actually are, at least there are some funds to pay for them. The issue is that we do not know, other than at the overall company level, whether this con- tribution has any bearing whatsoever on the real overheads involved in producing each particular product. ABM VIEW OF PRODUCT CONTRIBUTION (PRODUCT PROFITABILITY) In the product costing examples above, the ABM analysis uncovered the actual indirect and overhead costs associated with producing each product. Now when we calculate the revenue less the actual product costs, we have a number that is called the ABM Product Contribution. In other words, if this is a positive number, then we know that product costs are covered and the sum left over now con- tributes to the other overhead costs in the business such as sales, R&D, invoicing and so on.

    small donations ($1to $5,000) are particularly important to maintaining tax exempt status with the IRS. The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate. While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate. International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff. Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate. Section 5. General Information About Project Gutenberg™ electronic works Professor Michael S.

    Project Gutenberg™ eBooksare often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition. Most people start at our website which has the main PG search facility: www.gutenberg.org. This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
