Business Process Management (BPM)
What is it?
Body of principles, methods and tools to design,
analyze, execute and monitor and continuously
manage business processes
8
Processes and Outcomes
• Every process leads to one or several outcomes,
positive or negative
– Positive outcomes deliver value
– Negative outcomes reduce value
• Fault-to-resolution process
– Fault repaired without technician intervention
– Fault repaired with minor technician intervention
– Fault repaired and fully covered by warranty
– Fault repaired and partly covered by warranty
– Fault repaired but not covered by warranty
– Fault not repaired (customer withdrew request)
9
Rule of thumb
“If it does not make at least three
people mad, it’s not a process.”
Hammer and Stanton (1995)
10
Your turn
• Think of a process in your organization:
– Is it order-to-cash, procure-to-pay, fault-to-resolution…
– Who is/are the customer(s)?
– What value does this process deliver to its customer?
– Who are the key actors of the process?
– List at least 3 outcomes of the process.

Why BPM?
The Technology Perspective
“The first rule of any technology used in a business
is that automation applied to an efficient operation
will magnify the efficiency.
The second is that automation applied to an
inefficient operation will magnify the inefficiency.”
13
Why BPM? The Management Perspective

Process Identification – Steps
• Enumerate major processes
• Determine process boundaries (scoping)
• Assess strategic relevance of each process
• Assess of the “health” of each process
• Qualify the culture and politics of each process
• Back judgments with performance measures
See Davenport (1993)
Prioritized Processes & Performance Measures
20
Process Enumeration
“Most businesses have just three core processes:
1. Sell stuff
2. Deliver stuff
3. Making sure you have stuff to sell and deliver”
Geary Rummler
22
Process enumeration
• Typical number of processes is unclear
• Trade-off:
– ensuring process scope is manageable
– process scope determines potential impact
• Rule of thumb: 10-20 main processes
24
Process scoping
• Processes are interdependent
1. Hierarchical relations: Main processes – subprocesses
2. Upstream–downstream relations
• Key scoping questions:
1. When starts a given process instance?
2. When do we consider a process completed/closed?
3. What key objects does the process manipulates?
4. Who participates in the process?
5. Who owns the process?
25
Process Scoping
Rules of Thumb
• A well-scoped process:
– Has a clear start, clear end (input, output)
– Has a clear, coherent set of “main objects” and
“participants”
– Has a clear owner
28
Process selection
Three criteria:
1. Assess strategic relevance of each process
Strategic importance
1. Render high-level judgments of the “health” of
each process
Potential dysfunction
1. Qualify the culture and politics of each process
Feasibility

Purposes of Process Modeling
Communication,
simulation, activity-
based costing…
Detailed Models
including
Data types, conditions, data
mappings, fault handling…
Integration, testing,
deployment…
33
Business Process Modeling Notation
(BPMN)
• OMG Standard, supported by many tools:
– Bizagi Process Modeller (free)
– Signavio (http://www.signavio.com/) - subscription
– Oracle BPA – “kind of free”
– ARIS – very sophisticated but the opposite of free
– IBM Websphere Business Modeler
– Logizian – reasonable tradeoff
– Visio – Your company might already have this
– Paper and pen! - No excuse not to start
34
BPMN from 10 000 miles…
• A BPMN process model is a graph consisting of
four types of elements (among others):
36
When a claim is received, we first check if the claimant has a valid
insurance policy. If not, the claimant the claim is rejected and the
claimant is informed.
Otherwise, the severity of the claim is evaluated. Based on the
outcome (simple or complex claims), relevant forms are sent to the
claimant. Once the forms are returned, we check them for
completeness.
If the forms are complete, we register the claim in the Claims
Management system and the evaluation of the claim may start.
Otherwise, the claimant is asked to update the forms. Upon reception
of the updated forms, we check them again and continue.
BPMN Exercise:
Simplified Insurance Claim Registration
37
Guideline: Naming Conventions
• Give a name to every event and task
• For tasks: verb followed by business object
name and possibly complement
– Issue Driver Licence, Renew Licence via Agency
• Avoid generic verbs such as Handle, Record…
• Every XOR-split should be labelled with
conditions
– Policy is invalid, Claim is inadmissible
• For events: object + past participle
– Invoice received, Claim settled
39
Resource Modelling in BPMN
• In BPMN, resource classes are captured using:
– Pools – independent organizational entities, e.g.
• Customer, Supplier, East-Tallinn Hospital, Tartu Clinic
– Lanes – resource classes in the same organizational
space and sharing common systems
• Sales Department, Marketing Department
• Clerk, Manager, Engineer
41
BPMN Exercise: Lanes, Pools
• Claims Handling process at a car insurer
A customer submits a claim by sending in relevant
documentation. The Customer Service department
checks the documents for completeness and registers
the claim. The Claims Handling department picks up
the claim and first checks the insurance policy. Then,
an assessment is performed. If the assessment is
positive, a garage is phoned to authorise the repairs
and the payment is scheduled (in this order). In any
case (whether the outcome is positive or negative),
an e-mail is sent to the customer to notify the
outcome.
42
BPMN Information Artifacts
• Data Objects are a mechanism to show how
data is required or produced by activities.
– Are depicted by a rectangle that has its upper-right
corner folded over.
– Represent input and output of a process activity.
• Data stores are containers of data
objects that need be persisted beyond
the duration of a process instance
• Associations are used to link artifacts
such as data objects and data stores
with flow objects (e.g. activities).
Data
Store
44
When a claim related to a major car accident is evaluated, a clerk
first retrieves the corresponding car accident report in the Police
Reports database. If the report is retrieved, it is attached to the
claim file. The claim file and the police report serve as input to a
claims handler who calculates an initial claim estimate. Then, an
“action plan” is created based on a “checklist”. Based on the action
plan and the initial claims estimate, a claims manager negotiates a
settlement with the customer. After this negotiation, the claims
manager makes a final decision, updates the claim file to record this
decision, and sends a letter to the claimant to inform him/her of the
decision.
Depict all relevant documents in the model.
BPMN Exercise 3: Data Objects
47
Modeling Guideline
Start with a value chain
• Good practice is that the top-level process should
be simple (no gateways, no lanes) and should
show the main phases of the process
– Each phase then becomes a sub-process
– Top-level process is basically a value chain
• Introduce gateways and lanes at the next levels…
48
Guidelines: Modeling Levels
• First level: start with value chain
• Next level add:
– Main decisions
– Handoffs (lanes, see later)
• Only at the more detailed level add procedural
aspects:
– Parallel gateways
– Input and output data objects, data stores
– Different types of events
– And as much detail as you need
50
Question?
• What is the biggest pitfall of process modeling?
1. Using the wrong type of gateways, e.g. decision
gateway instead of parallel gateways
2. Writing process models from top-to-bottom instead
of left-to-right
3. Not following strictly the rules of the BPMN notation
4. Spending lots of time to produce detailed models
that nobody uses
54
Eliminating Waste
"All we are doing is looking at the time line, from
the moment the customer gives us an order to
the point when we collect the cash.
And we are reducing the time line by reducing
the non-value-adding wastes ”
Taiichi Ohno
55
7+1 Sources of Waste
1. Unnecessary Transportation (send, receive)
2. Inventory (large work-in-process)
3. Motion (drop-off, pick-up, go to)
4. Waiting (waiting time between tasks)
5. Over-Processing (performing what is not yet
needed or might not be needed)
6. Over-Production (unnecessary cases)
7. Defects (rework to fix defects)
8. Resource underutilization (idle resources)
Source: Seven Wastes defined by Taiichi Ohno

waste coined by Ben Chavis, Jr.
56
Value-Added Analysis
1. Decorticate the process into steps
2. Classify each step into:
– Value-adding (VA): Produces value or satisfaction to
the customer.
• Is the customer willing to pay for this step?
– Business value-adding (BVA): Necessary or useful for
the business to run smoothly, or required due to the
regulatory environment, e.g. checks, controls
• Would the business potentially suffer in the long-term if this
step was removed?
– Non-value-adding (NVA) – everything else including
handovers, delays and rework
59
Issue Register
• Purpose: to categorise identified issues as part of as-is
process modelling
• A table with the following columns (possibly others):
– issue number
– name
– Description/explanation
– Impact: Qualitative vs. Quantitative
– Possible resolution
60

Why-why analysis (equipment rental)
Site engineers keep equipment longer, why?
• Site engineer fears that equipment will not be available
later when needed, why?
– time between request and delivery too long, why?
• excessive time spent in finding a suitable equipment and approving
the request, why?
– time spent by clerk contacting possibly multiple suppliers sequentially;
– time spent waiting for works engineer to check the requests;
64
Pareto chart
• Useful to prioritize a collection of issues or
factors behind an issue
• Bar chart where the height of the bar denotes
the impact of each issue
67
Process Redesign
• Purpose: Identify possibilities for improving the
design of a process: “as is” “to be”
• No silver-bullet: requires creativity
• Redesign heuristics can be used to generate ideas
Descriprive modelling
of the real world (as-is)
Prescriptive modelling
of the real world (to-be)
69
The Ford Case Study (Hammer 1990)
Ford needed to review its procurement process to:
• Do it cheaper (cut costs)
• Do it faster (reduce turnaround times)
• Do it better (reduce error rates)
Accounts payable in North America alone employed
> 500 people and turnaround times for processing
POs and invoices was in the order of weeks
70
The Ford Case Study
• Automation would bring some improvement
(20% improvement)
• But Ford decided not to do it… Why?
a) Because at the time, the technology needed to
automate the process was not yet available.
b) Because nobody at Ford knew how to develop the
technology needed to automate the process.
c) Because there were not enough computers and
computer-literate employees at Ford.
d) None of the above
84
The result…
• 75% reduction in head count
• Material control is simpler and financial
information is more accurate
• Purchase requisition is faster
• Less overdue payments
Why automate something we don’t need to do?
Automate things that need to be done.
85
Principles of BPR
1. Capture information once and at the source
2. Subsume information-processing work into the
real work that produces the information
3. Have those who use the output of the process
drive the process
4. Treat geographically dispersed resources as if
they were centralized
90
Incremental Process Re-design
1. Select issues to address, improvement goals
2. Map goals to process performance measures
and set objectives/targets
3. Apply re-design heuristics on the “as is”
process model and analyze the tradeoffs
4. Select promising “change options”, justify and
prioritize their implementation
92
Redesign Heuristics
1. Task elimination
2. Task composition
3. Triage
4. Resequencing
5. Parallelism
6. Process specialization and
standardization
7. Resource optimization
8. Communication optimization
9. Automation
Each heuristics improves one side of the devil’s
quadrangle, generally to the detriment of others
93
Sample Heuristics
(8) Communication optimization
• Reduce the number of messages to be exchanged with
customers and business partners
– But avoid front-loading the process too much
– Not necessarily suitable if customer contact is desirable
• Monitor customer interactions, record exceptions,
determine what to front-load/back-load
• Try to automate handling, recording and organization of
messages (send/receive).

Specific Guidelines
The Complete Kit Concept
• Many processes follow the “complete kit” concept:
– Work should not begin until all pieces necessary to
complete the job are available
• In such cases, consider three principles:
– Provide complete and easy-to- follow instructions for
those who will initiate the process.
– If a process cannot start, the client should be notified of
all defects that could be reasonably identified at the
onset of the process.
– Consider the tradeoff between “incomplete-kit” process
initiation and roundtrip to revise and resubmit a request.

Final Words
• Any process is better than no process
• A good process is better than a bad process
• Even a good process can be improved
Michael Hammer
(1948 – 2008)
Editor's Notes
Business Process Management (BPM) is the art and science of overseeing how work is performed in an organization in view of ensuring consistent outcomes and identifying and taking advantage of improvement opportunities. In this context, the term ``improvement'' may take different meanings depending on the objectives of the organization. Typical examples of improvements include reducing costs, reducing execution times and reducing error rates. Importantly, BPM is not about improving the way individual activities are performed, but rather, it is about managing entire chains of events, activities and decisions that ultimately add value to the organization. Within the broad context of the above definition, BPM regroups a body of methods for managing business operations on the basis of process models. Process models represent the understanding that people in the organization have about how work is done or should be done. They act as the bridge between business operations and IT systems. They allow us to understand how IT systems contribute to adding value to the organization by streamlining its work practices.
Events correspond to things that happen ``atomically'', meaning that they have no duration. For example, the arrival of a plant to the depot is an event. This event may trigger the execution of series of activities. For example, when a plant arrives, the site engineer inspects the plant. This inspection is an activity, in the sense that it takes time. When an activity is rather simple and takes relatively little time, we call it a task. For example, if the inspection that the site engineer performs is quite simple -- e.g. just checking that the plant received corresponds to what was ordered -- we can say that the ``plant inspection'' is a task. If on the other hand the inspection of the plant requires many steps -- such as checking that the plant fulfills the specification included in the purchase order, checking that the plant is in working order, and checking the plant comes with all the required accessories and safety devices -- we will treat it as an ``activity''. The distinction between task and activity is not always clear-cut. This is why, very often people will use the term task and activity interchangeably. Order-to-cash: This is a process that starts when a customer places an order to purchase a product or a service, and ends when the product or service in question has been delivered and the corresponding payment has been received. An order-to-cash process encompasses activities such as purchase order verification, shipment (in the case of physical products), delivery, invoicing, payment receipt and acknowledgment. Quote-to-order: This process typically precedes the order-to-cash process. It starts from the point when a ``request for quote'' is received from a customer, to the point when the customer places a purchase order. The order-to-cash process takes the relay from that point on. The combination of a quote-to-order and the corresponding order-to-cash process is called a quote-to-cash process. Procure-to-pay: This is a process that starts when a stakeholder within an organization -- typically an employee -- determines that a given product or service needs to be purchased. It ends when the product or service has been delivered and paid for. A procure-to-pay process includes activities such as approving the purchase, obtaining quotes, selecting a supplier, issuing a purchase order, receiving the goods (or consuming the service), checking and paying the invoice. Procure-to-pay can be seen as the dual of quote-to-cash in the context of business-to-business interactions. For every procure-to-pay process there is a corresponding quote-to-cash process on the supplier's side. Issue-to-resolution. This is a process that starts when a customer raises a problem, such as a complaint related to a defect in a product or an issue encountered when consuming a service. The process continues until the customer, the supplier, or preferably both of them, agree that the issue has been resolved. A variant of this process can be found in insurance companies that have to deal with ``insurance claims''. This variant is often called claim-to-resolution.
The execution of a process leads to one or several \emph{outcomes}. For example, the above process leads to a plant being used by BuildIT, as well as a payment being made to the plant's supplier. These outcomes deliver \emph{value} to the key actors involved in the process, which in this example are BuildIT and the supplier. In some cases, this value is not achieved or is only partially achieved. For example, when a plant is returned, no value is gained, neither by BuildIT nor by the supplier. This corresponds to a \emph{negative outcome}, as opposed to a \emph{positive outcome} that delivers value to the actors involved.

BPM provides a natural ground for bridging IT and business, because many (perhaps most) IT projects in enterprises are ultimately aimed at improving a business process
Two points: We should remember all these disciplines have a common goal: to improve business performance and business value. So one should never pitch one discipline against another dogmatically. BPM is about managing and improving processes whatever it takes to do this. In some situations (e.g. continuous improvement initiatives) Six Sigma techniques are handy, so sure, let’s use them.

There are three dimensions where we typically look for process metrics: cost, time and quality. Do it faster, do it cheaper, do it better.
It is worth emphasizing here that activities located in two parallel paths do not need to be performed simultaneously. For example, “Send invoice” and “Ship goods” need not occur both at the same time, although due to a cosmic coincidence, they could happen at the same time. Instead, it might happen that first the invoice is sent and later the goods are shipped. Or things may happen in the reverse order.
The Functional perspective, indicates What tasks/function are happening in the process? The Control-flow perspective, indicates when should an activity be performed, that is, i n what order should activities and events occur? The resource perspective (also called organisational perspective) indicates Who performs which activity? Finally, the d ata perspective indicate which data are necessary to perform each activity and which data are produced by each activity in the process?
The process now includes two departments within the supplier organization…The purchase order received by the Sales & Distribution department has to be checked against the stock. The order details are sent to the Warehouse department that returns an availability notification. If the purchase order is confirmed, the Warehouse department collects the shipping details from the customer and ships the goods. The Sales & Distribution department sends an invoice to the customer who then makes the payment.
The Purchase Order document serves as an input to the stock availability check. Based on the outcome of this check, the status of document is updated, either to “approved” or “rejected”. We include here the relevant documents in the process model.
Hammer, M., (1990). "Reengineering Work: Don't Automate, Obliterate", Harvard Business Review, July/August, pp. 104–112.
Regarding the first principle, it is worth citing examples of process improvement patterns such as Self-Service and Vendor-Managed Inventory Control. Regarding, the second principle, self-service is again a typical example, particularly the ability for customers or workers to enter data themselves that goes directly into the organization’s databases Regarding the third principle, we can refer back to the idea of performing PO matching at delivery, rather than postponing this till the invoice is received
