Cost Center Practices in Germany and the United States:
Impact of Country Differences on Managerial Accounting
Practices
Kris Portz, St. Cloud State University
John C. Lere, University of Wisconsin—Milwaukee
Abstract
As business becomes increasingly global, it is important for
managers to appreci-
ate that practices that work well in one country may not work as
well in other
countries. This article compares cost center practices under
Grenzplankostenrech-
nung (GPK), a common approach to cost accounting in
Germany, and typical
cost center practices in the United States. Differences between
Germany and the
United States on Hofstede’s uncertainty avoidance dimension
and in workforce
and management education provide possible explanations for
differences in the
responsibility assigned to cost center managers between
Germany and the United
States. Differences in cost center practices concerning
classification of costs, mea-
sures to use when considering changes in costs, and the size and
scope of the cost
center between Germany and the United States all support these
differences in
cost center manager responsibility.

Introduction
Although business is global, differ-
ences in countries may mean that the
practice of business is not universal.
Certain country differences can impact
the effectiveness of managerial account-
ing practices and, as a consequence, af-
fect the appropriateness of the practices.
These country differences include dif-
ferences in culture, defined using Hofst-
ede’s taxonomy (2001), and workforce
and management education, which are
discussed in the present paper. Failure to
recognize the impact of country differ-
ences on the appropriateness of mana-
gerial accounting practices may lead to
a number of dysfunctional actions. A
company may benchmark against the
wrong set of companies. Managers and
accountants may accept “one size fits all”
solutions which do not fit all situations.
Companies may implement home-
country practices in subsidiaries located
in countries where the home-country
practices will be ineffective. The last de-
cade’s growth in international manageri-
al accounting research (Haka and Heit-
ger 2004, 21) is a sign of the potential
importance of recognizing the impact
of country differences on differences in
managerial accounting practices.
This article considers the impact of
country differences on differences in
cost center practices between Germa-
ny and the United States. The goals of
the article are to 1. describe cost center
practices that are an important part of
Grenzplankostenrechnung (GPK), a
common approach to cost accounting
in Germany, 2. contrast these practices
with cost center practices commonly
employed in the United States, and 3.
offer possible empirically testable ex-
planations for these major differences in
practices based on country differences.
The remainder of the article is divid-
ed into four sections. The next section
provides an analysis of previous research
and indicates where the present article
fits within the literature. This section is
followed by a section that describes dif-
ferences between cost center practices
common in Germany and cost center
practices common in the United States.
Section three describes important dif-
ferences in culture and education be-
tween Germany and the United States.
It also discusses how the differences be-
tween Germany and the United States
provide possible explanations for the
differences in cost center practices. The
article ends with a discussion of impli-
cations for managers and suggestions
for future research.
Analysis of Previous
Research
Because three recent articles re-
view the literature on international
management accounting (Harrison
and McKinnon 1999; Chenhall 2003;
46Spring 2010 • Vol. 25, No. 1
Portz and Lere
Haka and Heitger 2004), this article
does not include a detailed review. A
common thread to these articles is that
the dominant approach to distinguish-
ing countries is based on culture differ-
ences and that Hofstede’s taxonomy is
the most common approach to distin-
guishing culture (Harrison and McK-
innon, 1999; Chenhall 2003, 152-3;
Haka and Heitger 2004, 32). Haka and
Heitger (2004) do, however, consider
environmental factors that can have an
impact on how managerial account-
ing systems are designed in addition
to culture. They divide these factors
into four categories: (1) organization of
economic activity (2) political and legal
processes (3) culture (4) infrastructure
sophistication.
The present article considers envi-
ronmental factors that fall into two of
these categories: culture as defined us-
ing Hofstede’s taxonomy (culture) and
workforce and management education
(infrastructure sophistication).
The present article is unique in
that it considers managerial account-
ing practices in Germany. Germany
has not been included in prior work
on the impact of country differences
on managerial accounting practice
differences. Unlike most previous
work, this article bases its analysis
on data from secondary sources. This
approach permits a more general de-
scription of practices that is not sub-
ject to company specific differences
and the perceptions of respondents.
This does, of course, mean that the
practices compared may not reflect
the precise practices of any specific
company. Being more general, how-
ever, the description of practices may
be more indicative of the impact of
country differences on the practices.
A Review of German
and U.S. Cost Center
Practices
Although cost center practices vary
somewhat from firm to firm in the
United States, there is enough similar-
ity across firms that it is reasonable to
speak of common cost center practices
for the United States. Germany pro-
vides a unique opportunity for com-
parison. The Institute of Management
Accountants (IMA) has recently con-
ducted a number of studies of Gren-
zplankostenrechnung (GPK), a very
common approach to cost account-
ing in Germany (Kilger, Pampel, and
Vikas 2002, 15). Because cost center
practices are a very significant part of
GPK, the IMA studies provide a ba-
sis for describing common cost center
practices in Germany.
Differences in cost center practices
between Germany and the United
States can be divided into four cat-
egories: differences in the definition
of a cost center, differences in output
and activity measures used in the cost
centers, differences in the way in which
costs are classified in cost centers, and
differences in the responsibilities as-
signed to the heads of cost centers.
Cost Center Definition
In order for a subunit of a company
to be a cost center under GPK, it is
necessary that a single output measure
can be identified for that subunit. This
single output measure is intended to
describe the operations of the cost cen-
ter (Sharman 2003, 32). In the United
States, the only limitation imposed
on a cost center is that the decisions
made by the head of the cost center
are primarily ones that have an impact
on cost (Horngren, Datar, and Foster
2006, 197). Therefore, the limitations
placed on a United States cost center
are much less restrictive than the limi-
tations imposed under GPK. This al-
lows for cost centers that encompass
much broader operations.
Achieving the goal that operations of
the cost center can be represented by a
single output measure tends to result in
cost centers in Germany that are more
narrowly focused than are cost centers in
United States firms. For example, a cost
center in the United States that drills
parts might be divided into at least two
cost centers in Germany. One cost cen-
ter would set up the drilling machines;
the second cost center would operate
the machines to perform the drilling
operation. Such a division would per-
mit the firm to describe the operations
of each cost center by a single measure.
The output of the machine setup cost
center might be machine setups while
the output of the drilling cost center
might be parts drilled.
Achieving a narrow focus in GPK
cost centers tends to yield small cost
centers. Friedl, Küpper, and Pedell in-
dicate that a GPK cost center is typi-
cally composed of ten workers or less
(2005, 57). Because the less restric-
tive United States definition of a cost
center tends to yield cost centers with
broader operations than does the GPK
definition, cost centers in the United
States tend to be larger.
The difference in the definition of
a cost center also means that a com-
pany with a GPK system will typi-
cally have many more cost centers than
will a company following traditional
United States practices. An example
of this difference in number of cost
centers is provided by Sick Kids (a To-
ronto children’s hospital). At Sick Kids,
implementation of GPK resulted in a
dramatic increase in cost centers. For
example, in pilot departments, imple-
mentation raised the number of cost
centers from 29 to 97 (Mackie 2006,
35-6). Another example of the large
number of cost centers under GPK
is provided by DeutscheTelekom,
DT (German Telecom). The Inte-
“... a company with a GPK system will typically have
many more cost centers than will a company following
traditional United States practices.”
47Spring 2010 • Vol. 25, No. 1
Portz and Lere
grated Cost and Accounting Sys-
tem (IKE), an extension of GPK, at
DeutscheTelekom, DT, “captures cost
information about the efforts of ap-
proximately 120,000 people working
in 40,000 cost centers.” (Sharman and
Vikas 2004, 34).
Output and Activity Measures
The importance of an output mea-
sure in defining a cost center under
GPK results in differences between
Germany and the United States in the
measures used in cost centers. Measures
used in a GPK cost center are intended
1. to represent the output of the cost
center, not the output of the firm and 2.
to relate to the usage of resources.
This emphasis on measures of cost
center output is so basic to GPK that,
according to Krumwiede (2005, 34),
CIBA Specialty Chemicals doesn’t use
“GPK per se because of its complexity
and because, in chemical manufactur-
ing, it’s difficult to predict the output
quantity as some batches produce
more or less product than expected.
GPK requires that you are able to
predict outcomes fairly well, as in the
auto industry.”
In the United States, measures used
often do not represent the output of the
cost center. Under activity-based costing
(ABC), the measures selected represent
cost drivers for activities performed in
the cost center. Such a measure may
or may not represent the output of the
cost center (Horngren, Datar, and Fos-
ter 2006, 144-5). Other measures com-
monly used in the United States, such
as direct material cost, direct labor cost,
and direct labor hours represent mea-
sures with which a particular portion of
the cost center’s cost varies rather than
cost center output (Horngren, Datar,
and Foster 2006, 32).
Because GPK measures are also se-
lected to relate to resource usage, some
measures that represent the output of a
cost center might not be as appropriate
for use in GPK. For example, a measure
such as number of setups might not be
an appropriate GPK output measure.
While it may represent the output of a
cost center, it may not be as closely tied
to resource usage as are other measures.
If there are differences in the setups
performed by the cost center such that
some setups take longer, a measure such
as setup hours might better relate to use
of resources. In such a case, setup hours
would be preferred to number of setups
as an output measure for the cost center
(Keys and van der Merwe 1999, 3).
The emphasis on resource usage
means that many measures commonly
used in the United States may not be
appropriate output measures under
GPK. While the relationship between
cost and some measures used in the
United States is one of cause and effect,
the relationship is often only a statisti-
cal one. As discussed below, measures
only having a statistical relationship
with cost may not provide GPK man-
agers with the information appropriate
to their responsibilities.
The GPK focus on defining cost
centers with one measure of output
that is related to resource usage leads
to cost classification under GPK
that is narrower than is typical in the
United States. A fundamental feature
of GPK is that cost center’s costs are
divided into those that are (1) propor-
tional and (2) fixed.
Classifications of Costs
in a Cost Center
Classification of costs in a cost cen-
ter into proportional costs and fixed
costs is a third important way in which
GPK cost center practices differ from
those of the United States. For that
portion of the center’s cost deemed to
be proportional, an increase (decrease)
in the output measure for the cost cen-
ter is accompanied by a proportional
increase (decrease) in cost. The remain-
ing costs of the cost center are classi-
fied as fixed. Traditionally, costs in the
United States are divided into variable
costs and fixed costs. As used in the
United States, the term “variable cost”
is a more general term. It is typically
applied to costs whose total change in
proportion to change in some measure
of activity or volume which may or may
not be a measure of output (Horngren,
Datar, and Foster 2006, 30).
The very precise meaning of “pro-
portional costs” under GPK can eas-
ily cause confusion. As used in the
United States, “variable costs” as well
as activity-based costing costs that vary
with unit-level, batch-level, and prod-
uct-level activities are typically propor-
tional costs to the measure with which
they vary. Therefore, a United States
cost center may include many costs
that vary proportionately with some
measure. As used in GPK, however,
“proportional costs” are limited to only
those costs that are proportional to
changes in cost center output. Because
a GPK cost center is defined so that its
operations can be represented by one
output measure, its proportional costs
all vary with the same measure.
The importance of the proportion-
al/fixed cost dichotomy to GPK firms
is illustrated by Krumwiede’s (2005,
32-3) discussion of Magna Steyer, a
supplier of original equipment to auto
manufacturers. “Magna accountants
told me they don’t use ABC … because
ABC doesn’t separate fixed and [pro-
portional] costs.”
Responsibilities of Cost Center
Managers
The final area in which GPK cost
center practices differ from United
States cost center practices relates to
the assignment of responsibilities to
cost center managers. There are two
important aspects of this assignment:
“Measures used in a GPK cost center are intended (1) to
represent the output of the cost center, not the output of
the firm and (2) to relate to the usage of resources.”
48Spring 2010 • Vol. 25, No. 1
Portz and Lere
The manager is responsible for see-•
ing that costs adjust in response to
changes in output of the cost center.
A manager may be responsible for •
more than one cost center.
A major distinction between Ger-
man and United States cost center
practices relates to the primary respon-
sibility of cost center managers. GPK
considers the cost center manager’s
prime responsibility to be seeing that
costs adjust in response to changes
in the output of the cost center. This
link between the objective of manag-
ers and GPK is clearly indicated in the
definition of GPK translated from the
introduction to the preeminent Ger-
man cost accounting textbook. GPK
is “a comprehensive and sophisticated
method of planning and monitoring
costs based on resource drivers. Select-
ing the resource drivers and separating
the costs into fixed and proportional
components ensures that cost fluctua-
tions caused by changes in operating
levels, as defined by marginal analysis,
are accurately predicted as changes in
authorized costs and incorporated into
variance analysis.” (Kilger, Pampel, and
Vikas 2002, 7). “Authorized” is used in
the translation for a word that conveys
the meaning of target or allowed costs.
Therefore, this definition underscores
the emphasis on assuring that costs
adjust in response to changes in cost
center output.
This emphasis on cost adjustment
focuses the manager’s effort and at-
tention on one thing, responding to
changes in the output of the cost cen-
ter. As a result, GPK is likely to lead
to greater responsiveness of costs to
changes in cost center output than do
systems common in the United States
in which the manager has broader re-
sponsibilities.
Because the primary responsibility
of a cost center manager in the United
States is typically more broadly defined
as to control all costs incurred within
the cost center (Horngren, Datar, and
Foster 2006, 197), opportunities for
cost reduction such as by reducing
cost center output and by tradeoffs
that reduce one cost while increasing
another cost by a smaller amount are
more likely to be identified and imple-
mented by cost center managers in the
United States than by cost center man-
agers in Germany (Friedl, Küpper, and
Pedell 2005, 61).
A second difference between Ger-
many and the United States in assign-
ment of responsibilities to cost center
managers relates to the number of
cost centers managed. Although only
one manager is typically in charge of
each cost center in both Germany and
the United States, a GPK cost center
manager is often responsible for more
than one cost center while cost cen-
ter managers in the United States are
typically responsible for only one cost
center. When GPK was implemented
at Sick Kids, managers who had previ-
ously been responsible for a single cost
center were now responsible for four or
five GPK cost centers (Mackie 2006,
36).
Table 1 summarizes these impor-
tant differences between cost centers
under GPK and cost centers typical in
the United States.
Influences on Cost
Center Design
In developing a link between coun-
try differences and cost center practice
differences, this article considers the
difference between the major respon-
sibilities assigned to cost center man-
agers under GPK and in the United
States to be the one directly related to
differences in country culture and edu-
cation. Differences between Germany

ter all support this difference in assign-
ment of responsibilities.
The section begins by discussing
cross-country culture and education
differences as possible explanations for
the differences in major responsibilities
assigned to cost center managers.
Culture Influence
on Major Responsibilities
A number of social researchers
(Kluckholn and Strodtbeck 1961, Hall
1977, Hofstede 2001, and Trompenaars
and Hampden-Turner 1998) have de-
signed theoretical frameworks to ex-
plain why people from different coun-
tries do things in different ways. This
article uses Hofstede’s taxonomy, which
distinguishes a country’s culture based
on its position on five dimensions:
power distance, uncertainty avoidance,
individualism/collectivism, masculine/
feminine, and Confucian dynamism.
Although they differ somewhat on
each dimension, Germany and the
United States differ most significantly
on the uncertainty avoidance dimen-
sion (Hofstede 2001, 87, 151, 215,
286, 356). Germany is considered a
strong uncertainty avoidance country
while the United States is considered
a weak uncertainty avoidance country.
According to Hofstede: “Many read-
ers of my earlier work have interpreted
‘uncertainty avoidance’ as ‘risk avoid-
ance’… . But uncertainty avoidance
does not equal risk avoidance.” “More
than an escape from risk, uncertainty
avoidance leads to an escape from am-
biguity.” (Hofstede 2001, 148).
Based on Hofstede’s discussion of
strong and weak uncertainty avoidance
cultures, one would expect systems in
which managers are faced with rela-
tively little ambiguity in strong uncer-
tainty avoidance cultures. Managers in
weak uncertainty avoidance cultures are
more likely to function in systems pre-
senting them with greater ambiguity.
Assignment of cost center manager
responsibility under GPK is consistent
with the strong uncertainty avoid-
ance culture found in Germany. Un-
der GPK, a firm has narrowly defined
cost centers where a manager who is
responsible for the cost center focuses
on controlling proportional costs. As
a result, cost center managers are able
to become very competent at manag-
ing narrowly focused operations with
a repetitive output. Such a structure
tends to reduce the ambiguity that a
manager faces.
Strong uncertainty avoidance also
results in a preference for focusing
on accomplishing a set of tasks. Once
workers know their duties, their pri-
mary goal is to complete their assigned
tasks (Schmidt 2007, 47). Because of
the focus on managing costs so that
they respond to changes in output,
managers have well-defined roles with-
in cost centers and can focus on their
designated repetitive, consistent, pre-
dictable tasks. This too tends to reduce
the ambiguity faced by managers.
Because of its weak uncertainty
avoidance culture, managers in the
United States generally prefer less
structure and more flexibility. Manag-
ers are often encouraged to work inter-
departmentally to improve productiv-
ity and efficiency. The strict cost-center
criteria of GPK is inconsistent with a
desire for flexibility by United States
managers. Small cost centers focus-
ing on narrow tasks may make United
States managers feel too confined or
even constrained from being creative.
As a result, the prevalent United States
culture may make it difficult for man-
agers to accept the structure and rigid-
ity of GPK.
Education Influence
on Major Responsibilities
Significant differences also exist be-
tween workforce and management ed-
ucation in Germany and in the United
States. In Germany, young people are
trained as skilled workers for specific
jobs through apprenticeships. Practi-
cal work with on the job training al-
ternates with classroom courses over
an apprenticeship period. At the end
of the apprenticeship, workers receive a
certificate, which is highly valued and
instills a sense of occupational pride.
Therefore, German managers over-
see highly qualified individuals who
are specially trained for their positions
(Schmidt 2007, 52). The United States
workforce generally lacks such specific
training. Workers are often considered
“jack of all trades” with little formal
training for specific jobs other than
what may be acquired on the job.
Most German managers are edu-
cated as technical experts. In fact, over
60 percent of German manufacturing
companies are run by engineers with
Ph.D. degrees. Any management skills
are usually learned on the shop floor.
Managers in the United States, on
the other hand, tend to be educated as
MBAs rather than as technical experts.
An effective manager in the United
States leads or guides a group. A man-
ager usually does not produce person-
ally but is good at making others in the
group produce through “motivation”
(Schmidt 2007, 53).
Because German workers are in-
nately self-motivated and often work
hard for the good of the group, efforts
to “motivate” them would be seen as
unnecessary hand-holding and an in-
sult to their professional pride. There-
fore, German managers see little rea-
son to learn about motivating or even
supervising personnel. They assume
work will be done well without any
prodding (Schmidt 2007, 53). Overall,
United States firms give management
authority to make strategic decisions
whereas German businesses see man-
agers as less of a key factor to success.
Differences between workforce
education in Germany and the United
States are consistent with the differ-
ence in assignment of responsibility
between GPK and United States cost
center practices. A narrow focus in
cost center manager responsibility in
Germany facilitates well-defined spe-
cific jobs for which young people can
be trained. Because the United States
workforce generally lacks such specific
training, such well-defined jobs are
not necessary to facilitate education.
50Spring 2010 • Vol. 25, No. 1
Portz and Lere
The difference in education between
German managers and United States
managers is also consistent with differ-
ences in the assignment of responsibil-
ities between GPK and United States
cost practices. United States managers
tend to be educated to manage which
implies a broader range of responsibili-
ties including motivating while man-
agement education tends to be very in-
formal in Germany and therefore may
not support as broad responsibilities.
Cost Classification,
Measures Used, and Cost
Center Definition
In order for managers under GPK
to fulfill the responsibility of ensur-
ing that changes in output levels are
reflected in changes in costs, the man-
agers must know which costs are ex-
pected to respond to changes in output
levels. Therefore, the GPK emphasis
on classifying costs into proportional
versus fixed identifies the costs that the
managers can and are expected to con-
trol, the proportional costs.
Identifying proportional costs,
those that change in proportion with
cost center output, as opposed to vari-
able costs, those that vary with some
measure, also enhances the ability of
GPK managers to fulfill their respon-
sibility. Because the output measure
for a cost center is chosen to relate to
resource usage, the GPK concept of a
proportional cost is more strongly tied
to cause and effect than is the concept
of a variable cost. While there may be
a cause and effect relationship between
a variable cost and cost center output,
variable costs often have only a statisti-
cal association with some measure that
is often not cost center output. There-
fore, the identification of proportional
costs provides a GPK cost center man-
ager with information on costs that he
or she should be able to control as cost
center output changes while identifi-
cation of variable costs may or may not
provide such information.
The United States cost center man-
ager, however, is typically responsible
for managing the costs of a cost center
in ways that include, but are not lim-
ited to, the cost control responsibility
of a GPK cost center manager. Iden-
tification of variable costs as well as
those costs identified under activity-
based costing as changing with chang-
es in the amount of unit-level activity,
batch-level activity, or product-level
activity is appropriate to support the
broader responsibilities of a United
States cost center manager. Because
a cost center manager in the United
States is responsible for controlling
costs in a much wider variety of ways,
he or she can potentially make use of a
much broader set of measures. In addi-
tion, the broader focus of a cost center
in the United States may mean that
the cost center does not have a single
output measure. Therefore, multiple
output measures may be appropriate in
the United States.
Cost centers with a narrow focus are
necessary in order to assign responsibil-
ity for ensuring that proportional costs
change in response to changes in cost
center output to GPK cost center man-
agers. Only with a very narrow focus can
a cost center’s operations be described
using one output measure. This narrow
focus explains the relatively small size of
cost centers under GPK and their rela-
tively large number per firm.
The GPK practice of assigning mul-
tiple cost centers to a manager likely
arises because the GPK definition of
a cost center leads to many, fairly small
cost centers. If a unique manager was
assigned to each cost center, a company
would have an extremely large number
of cost center managers, each with a
fairly limited set of responsibilities.
This would not seem to be an efficient
use of resources.
In the United States, the respon-
sibilities of a cost center manager are
typically broader than those under
GPK. In order to make the types of
decision typically made by a United
States cost center manager, the cost
center must be more broadly defined
to allow for cost trade offs. This is con-
sistent with the larger size of a typi-
cal United States cost center and with
the smaller number of cost centers in a
typical United States firm.
Discussion
This section discusses cross-country
differences in culture and education as
potential explanations for cost center
practice differences and offers impli-
cations of these explanations. These
implications are divided into ones of
interest to managers considering im-
plementing GPK and ones of interest
to those considering future research.
Implications for Managers
When considering potential imple-
mentation of GPK, it is important to
consider both the types of decisions
that a company wishes its managers to
make and the possibility that culture
and education differences between the
United States and Germany may make
GPK less effective in a United States
company than in a German company.
GPK cost center practices focus
managers’ decisions primarily on cost
reduction as a response to changes in
cost center output. Therefore, it is im-
portant for a company to consider the
extent to which it wants managers to
look for ways to reduce cost center
cost 1. by reducing the cost center out-
put, 2. by looking for tradeoffs among
costs and 3. by considering other ways
to reduce costs that are not related to
changes in cost center output.
Typical United States cost center
practices are better designed to support
decisions related to these types of cost
reduction than are GPK practices.
In addition, because culture and
education differences imply different
preferences and preparation for respon-
sibilities, it is also important for firms
considering implementing GPK cost
center practices to consider
if firm managers will be effective 1.
with the narrower job focus and lim-
ited ability to be involved in strategic
or interdepartmental decision mak-
ing under GPK and
if the focus on narrow tasks will make 2.

managers feel too confined or even
constrained from being creative.
Suggestions for Future
Research
This article uses differences in cost
center practices between the United
States and Germany to explore pos-
sible relationships between (1) culture
and (2) education of the workforce and
managers and managerial accounting
practices. In doing so, it suggests sev-
eral directions for further research.
One direction for future research is
to determine if the differences in cost
center practices are related to differ-
ences in culture, education, or both.
An approach to answering this ques-
tion would involve identifying Ger-
man companies whose employees (1)
are German, but have been educated
in the United States, (2) are German
and have been educated in Germany
or (3) have been educated in Ger-
many, but have spent substantial time
in the United States. Comparisons of
the cost center practices among com-
panies whose employees fit in these
three categories may shed light on the
impact of each factor.
Differences between German
workforce and management education
and workforce and management edu-
cation in the United States are con-
sistent with culture differences related
to uncertainty avoidance (Hofstede
2001, 170). Therefore, another ques-
tion of interest is whether differences
in both cost center practices and edu-
cation arise because of differences in
country culture. Culture may be the
main factor behind cost center practice
differences directly and also indirectly
through differences in the workforce
and management education.

  • 1. 45Spring 2010 • Vol. 25, No. 1 Cost Center Practices in Germany and the United States: Impact of Country Differences on Managerial Accounting Practices Kris Portz, St. Cloud State University John C. Lere, University of Wisconsin—Milwaukee Abstract As business becomes increasingly global, it is important for managers to appreci- ate that practices that work well in one country may not work as well in other countries. This article compares cost center practices under Grenzplankostenrech- nung (GPK), a common approach to cost accounting in Germany, and typical cost center practices in the United States. Differences between Germany and the United States on Hofstede’s uncertainty avoidance dimension and in workforce and management education provide possible explanations for differences in the responsibility assigned to cost center managers between Germany and the United States. Differences in cost center practices concerning classification of costs, mea- sures to use when considering changes in costs, and the size and scope of the cost center between Germany and the United States all support these differences in
  • 2. cost center manager responsibility. Keywords: cost centers, German cost accounting, Hofstede, responsibility accounting Introduction Although business is global, differ- ences in countries may mean that the practice of business is not universal. Certain country differences can impact the effectiveness of managerial account- ing practices and, as a consequence, af- fect the appropriateness of the practices. These country differences include dif- ferences in culture, defined using Hofst- ede’s taxonomy (2001), and workforce and management education, which are discussed in the present paper. Failure to recognize the impact of country differ- ences on the appropriateness of mana- gerial accounting practices may lead to a number of dysfunctional actions. A company may benchmark against the wrong set of companies. Managers and accountants may accept “one size fits all” solutions which do not fit all situations. Companies may implement home- country practices in subsidiaries located in countries where the home-country practices will be ineffective. The last de- cade’s growth in international manageri- al accounting research (Haka and Heit- ger 2004, 21) is a sign of the potential importance of recognizing the impact
  • 3. of country differences on differences in managerial accounting practices. This article considers the impact of country differences on differences in cost center practices between Germa- ny and the United States. The goals of the article are to 1. describe cost center practices that are an important part of Grenzplankostenrechnung (GPK), a common approach to cost accounting in Germany, 2. contrast these practices with cost center practices commonly employed in the United States, and 3. offer possible empirically testable ex- planations for these major differences in practices based on country differences. The remainder of the article is divid- ed into four sections. The next section provides an analysis of previous research and indicates where the present article fits within the literature. This section is followed by a section that describes dif- ferences between cost center practices common in Germany and cost center practices common in the United States. Section three describes important dif- ferences in culture and education be- tween Germany and the United States. It also discusses how the differences be- tween Germany and the United States provide possible explanations for the differences in cost center practices. The article ends with a discussion of impli-
  • 4. cations for managers and suggestions for future research. Analysis of Previous Research Because three recent articles re- view the literature on international management accounting (Harrison and McKinnon 1999; Chenhall 2003; 46Spring 2010 • Vol. 25, No. 1 Portz and Lere Haka and Heitger 2004), this article does not include a detailed review. A common thread to these articles is that the dominant approach to distinguish- ing countries is based on culture differ- ences and that Hofstede’s taxonomy is the most common approach to distin- guishing culture (Harrison and McK- innon, 1999; Chenhall 2003, 152-3; Haka and Heitger 2004, 32). Haka and Heitger (2004) do, however, consider environmental factors that can have an impact on how managerial account- ing systems are designed in addition to culture. They divide these factors into four categories: (1) organization of economic activity (2) political and legal processes (3) culture (4) infrastructure
  • 5. sophistication. The present article considers envi- ronmental factors that fall into two of these categories: culture as defined us- ing Hofstede’s taxonomy (culture) and workforce and management education (infrastructure sophistication). The present article is unique in that it considers managerial account- ing practices in Germany. Germany has not been included in prior work on the impact of country differences on managerial accounting practice differences. Unlike most previous work, this article bases its analysis on data from secondary sources. This approach permits a more general de- scription of practices that is not sub- ject to company specific differences and the perceptions of respondents. This does, of course, mean that the practices compared may not reflect the precise practices of any specific company. Being more general, how- ever, the description of practices may be more indicative of the impact of country differences on the practices. A Review of German and U.S. Cost Center Practices Although cost center practices vary somewhat from firm to firm in the
  • 6. United States, there is enough similar- ity across firms that it is reasonable to speak of common cost center practices for the United States. Germany pro- vides a unique opportunity for com- parison. The Institute of Management Accountants (IMA) has recently con- ducted a number of studies of Gren- zplankostenrechnung (GPK), a very common approach to cost account- ing in Germany (Kilger, Pampel, and Vikas 2002, 15). Because cost center practices are a very significant part of GPK, the IMA studies provide a ba- sis for describing common cost center practices in Germany. Differences in cost center practices between Germany and the United States can be divided into four cat- egories: differences in the definition of a cost center, differences in output and activity measures used in the cost centers, differences in the way in which costs are classified in cost centers, and differences in the responsibilities as- signed to the heads of cost centers. Cost Center Definition In order for a subunit of a company to be a cost center under GPK, it is necessary that a single output measure can be identified for that subunit. This single output measure is intended to
  • 7. describe the operations of the cost cen- ter (Sharman 2003, 32). In the United States, the only limitation imposed on a cost center is that the decisions made by the head of the cost center are primarily ones that have an impact on cost (Horngren, Datar, and Foster 2006, 197). Therefore, the limitations placed on a United States cost center are much less restrictive than the limi- tations imposed under GPK. This al- lows for cost centers that encompass much broader operations. Achieving the goal that operations of the cost center can be represented by a single output measure tends to result in cost centers in Germany that are more narrowly focused than are cost centers in United States firms. For example, a cost center in the United States that drills parts might be divided into at least two cost centers in Germany. One cost cen- ter would set up the drilling machines; the second cost center would operate the machines to perform the drilling operation. Such a division would per- mit the firm to describe the operations of each cost center by a single measure. The output of the machine setup cost center might be machine setups while the output of the drilling cost center might be parts drilled. Achieving a narrow focus in GPK
  • 8. cost centers tends to yield small cost centers. Friedl, Küpper, and Pedell in- dicate that a GPK cost center is typi- cally composed of ten workers or less (2005, 57). Because the less restric- tive United States definition of a cost center tends to yield cost centers with broader operations than does the GPK definition, cost centers in the United States tend to be larger. The difference in the definition of a cost center also means that a com- pany with a GPK system will typi- cally have many more cost centers than will a company following traditional United States practices. An example of this difference in number of cost centers is provided by Sick Kids (a To- ronto children’s hospital). At Sick Kids, implementation of GPK resulted in a dramatic increase in cost centers. For example, in pilot departments, imple- mentation raised the number of cost centers from 29 to 97 (Mackie 2006, 35-6). Another example of the large number of cost centers under GPK is provided by DeutscheTelekom, DT (German Telecom). The Inte- “... a company with a GPK system will typically have many more cost centers than will a company following traditional United States practices.”
  • 9. 47Spring 2010 • Vol. 25, No. 1 Portz and Lere grated Cost and Accounting Sys- tem (IKE), an extension of GPK, at DeutscheTelekom, DT, “captures cost information about the efforts of ap- proximately 120,000 people working in 40,000 cost centers.” (Sharman and Vikas 2004, 34). Output and Activity Measures The importance of an output mea- sure in defining a cost center under GPK results in differences between Germany and the United States in the measures used in cost centers. Measures used in a GPK cost center are intended 1. to represent the output of the cost center, not the output of the firm and 2. to relate to the usage of resources. This emphasis on measures of cost center output is so basic to GPK that, according to Krumwiede (2005, 34), CIBA Specialty Chemicals doesn’t use “GPK per se because of its complexity and because, in chemical manufactur- ing, it’s difficult to predict the output quantity as some batches produce more or less product than expected. GPK requires that you are able to predict outcomes fairly well, as in the auto industry.”
  • 10. In the United States, measures used often do not represent the output of the cost center. Under activity-based costing (ABC), the measures selected represent cost drivers for activities performed in the cost center. Such a measure may or may not represent the output of the cost center (Horngren, Datar, and Fos- ter 2006, 144-5). Other measures com- monly used in the United States, such as direct material cost, direct labor cost, and direct labor hours represent mea- sures with which a particular portion of the cost center’s cost varies rather than cost center output (Horngren, Datar, and Foster 2006, 32). Because GPK measures are also se- lected to relate to resource usage, some measures that represent the output of a cost center might not be as appropriate for use in GPK. For example, a measure such as number of setups might not be an appropriate GPK output measure. While it may represent the output of a cost center, it may not be as closely tied to resource usage as are other measures. If there are differences in the setups performed by the cost center such that some setups take longer, a measure such as setup hours might better relate to use of resources. In such a case, setup hours would be preferred to number of setups
  • 11. as an output measure for the cost center (Keys and van der Merwe 1999, 3). The emphasis on resource usage means that many measures commonly used in the United States may not be appropriate output measures under GPK. While the relationship between cost and some measures used in the United States is one of cause and effect, the relationship is often only a statisti- cal one. As discussed below, measures only having a statistical relationship with cost may not provide GPK man- agers with the information appropriate to their responsibilities. The GPK focus on defining cost centers with one measure of output that is related to resource usage leads to cost classification under GPK that is narrower than is typical in the United States. A fundamental feature of GPK is that cost center’s costs are divided into those that are (1) propor- tional and (2) fixed. Classifications of Costs in a Cost Center Classification of costs in a cost cen- ter into proportional costs and fixed costs is a third important way in which GPK cost center practices differ from those of the United States. For that portion of the center’s cost deemed to
  • 12. be proportional, an increase (decrease) in the output measure for the cost cen- ter is accompanied by a proportional increase (decrease) in cost. The remain- ing costs of the cost center are classi- fied as fixed. Traditionally, costs in the United States are divided into variable costs and fixed costs. As used in the United States, the term “variable cost” is a more general term. It is typically applied to costs whose total change in proportion to change in some measure of activity or volume which may or may not be a measure of output (Horngren, Datar, and Foster 2006, 30). The very precise meaning of “pro- portional costs” under GPK can eas- ily cause confusion. As used in the United States, “variable costs” as well as activity-based costing costs that vary with unit-level, batch-level, and prod- uct-level activities are typically propor- tional costs to the measure with which they vary. Therefore, a United States cost center may include many costs that vary proportionately with some measure. As used in GPK, however, “proportional costs” are limited to only those costs that are proportional to changes in cost center output. Because a GPK cost center is defined so that its operations can be represented by one output measure, its proportional costs
  • 13. all vary with the same measure. The importance of the proportion- al/fixed cost dichotomy to GPK firms is illustrated by Krumwiede’s (2005, 32-3) discussion of Magna Steyer, a supplier of original equipment to auto manufacturers. “Magna accountants told me they don’t use ABC … because ABC doesn’t separate fixed and [pro- portional] costs.” Responsibilities of Cost Center Managers The final area in which GPK cost center practices differ from United States cost center practices relates to the assignment of responsibilities to cost center managers. There are two important aspects of this assignment: “Measures used in a GPK cost center are intended (1) to represent the output of the cost center, not the output of the firm and (2) to relate to the usage of resources.” 48Spring 2010 • Vol. 25, No. 1 Portz and Lere The manager is responsible for see-• ing that costs adjust in response to changes in output of the cost center. A manager may be responsible for •
  • 14. more than one cost center. A major distinction between Ger- man and United States cost center practices relates to the primary respon- sibility of cost center managers. GPK considers the cost center manager’s prime responsibility to be seeing that costs adjust in response to changes in the output of the cost center. This link between the objective of manag- ers and GPK is clearly indicated in the definition of GPK translated from the introduction to the preeminent Ger- man cost accounting textbook. GPK is “a comprehensive and sophisticated method of planning and monitoring costs based on resource drivers. Select- ing the resource drivers and separating the costs into fixed and proportional components ensures that cost fluctua- tions caused by changes in operating levels, as defined by marginal analysis, are accurately predicted as changes in authorized costs and incorporated into variance analysis.” (Kilger, Pampel, and Vikas 2002, 7). “Authorized” is used in the translation for a word that conveys the meaning of target or allowed costs. Therefore, this definition underscores the emphasis on assuring that costs adjust in response to changes in cost center output. This emphasis on cost adjustment focuses the manager’s effort and at-
  • 15. tention on one thing, responding to changes in the output of the cost cen- ter. As a result, GPK is likely to lead to greater responsiveness of costs to changes in cost center output than do systems common in the United States in which the manager has broader re- sponsibilities. Because the primary responsibility of a cost center manager in the United States is typically more broadly defined as to control all costs incurred within the cost center (Horngren, Datar, and Foster 2006, 197), opportunities for cost reduction such as by reducing cost center output and by tradeoffs that reduce one cost while increasing another cost by a smaller amount are more likely to be identified and imple- mented by cost center managers in the United States than by cost center man- agers in Germany (Friedl, Küpper, and Pedell 2005, 61). A second difference between Ger- many and the United States in assign- ment of responsibilities to cost center managers relates to the number of cost centers managed. Although only one manager is typically in charge of each cost center in both Germany and the United States, a GPK cost center manager is often responsible for more than one cost center while cost cen-
  • 16. ter managers in the United States are typically responsible for only one cost center. When GPK was implemented at Sick Kids, managers who had previ- ously been responsible for a single cost center were now responsible for four or five GPK cost centers (Mackie 2006, 36). Table 1 summarizes these impor- tant differences between cost centers under GPK and cost centers typical in the United States. Influences on Cost Center Design In developing a link between coun- try differences and cost center practice differences, this article considers the difference between the major respon- sibilities assigned to cost center man- agers under GPK and in the United States to be the one directly related to differences in country culture and edu- cation.

The section begins by discussing
  • 19. cross-country culture and education differences as possible explanations for the differences in major responsibilities assigned to cost center managers. Culture Influence on Major Responsibilities A number of social researchers (Kluckholn and Strodtbeck 1961, Hall 1977, Hofstede 2001, and Trompenaars and Hampden-Turner 1998) have de- signed theoretical frameworks to ex- plain why people from different coun- tries do things in different ways. This article uses Hofstede’s taxonomy, which distinguishes a country’s culture based on its position on five dimensions: power distance, uncertainty avoidance, individualism/collectivism, masculine/ feminine, and Confucian dynamism. Although they differ somewhat on each dimension, Germany and the United States differ most significantly on the uncertainty avoidance dimen- sion (Hofstede 2001, 87, 151, 215, 286, 356). Germany is considered a strong uncertainty avoidance country while the United States is considered a weak uncertainty avoidance country. According to Hofstede: “Many read- ers of my earlier work have interpreted ‘uncertainty avoidance’ as ‘risk avoid- ance’… . But uncertainty avoidance does not equal risk avoidance.” “More
  • 20. than an escape from risk, uncertainty avoidance leads to an escape from am- biguity.” (Hofstede 2001, 148). Based on Hofstede’s discussion of strong and weak uncertainty avoidance cultures, one would expect systems in which managers are faced with rela- tively little ambiguity in strong uncer- tainty avoidance cultures. Managers in weak uncertainty avoidance cultures are more likely to function in systems pre- senting them with greater ambiguity. Assignment of cost center manager responsibility under GPK is consistent with the strong uncertainty avoid- ance culture found in Germany. Un- der GPK, a firm has narrowly defined cost centers where a manager who is responsible for the cost center focuses on controlling proportional costs. As a result, cost center managers are able to become very competent at manag- ing narrowly focused operations with a repetitive output. Such a structure tends to reduce the ambiguity that a manager faces. Strong uncertainty avoidance also results in a preference for focusing on accomplishing a set of tasks. Once workers know their duties, their pri- mary goal is to complete their assigned tasks (Schmidt 2007, 47). Because of
  • 21. the focus on managing costs so that they respond to changes in output, managers have well-defined roles with- in cost centers and can focus on their designated repetitive, consistent, pre- dictable tasks. This too tends to reduce the ambiguity faced by managers. Because of its weak uncertainty avoidance culture, managers in the United States generally prefer less structure and more flexibility. Manag- ers are often encouraged to work inter- departmentally to improve productiv- ity and efficiency. The strict cost-center criteria of GPK is inconsistent with a desire for flexibility by United States managers. Small cost centers focus- ing on narrow tasks may make United States managers feel too confined or even constrained from being creative. As a result, the prevalent United States culture may make it difficult for man- agers to accept the structure and rigid- ity of GPK. Education Influence on Major Responsibilities Significant differences also exist be- tween workforce and management ed- ucation in Germany and in the United States. In Germany, young people are trained as skilled workers for specific jobs through apprenticeships. Practi- cal work with on the job training al-
  • 22. ternates with classroom courses over an apprenticeship period. At the end of the apprenticeship, workers receive a certificate, which is highly valued and instills a sense of occupational pride. Therefore, German managers over- see highly qualified individuals who are specially trained for their positions (Schmidt 2007, 52). The United States workforce generally lacks such specific training. Workers are often considered “jack of all trades” with little formal training for specific jobs other than what may be acquired on the job. Most German managers are edu- cated as technical experts. In fact, over 60 percent of German manufacturing companies are run by engineers with Ph.D. degrees. Any management skills are usually learned on the shop floor. Managers in the United States, on the other hand, tend to be educated as MBAs rather than as technical experts. An effective manager in the United States leads or guides a group. A man- ager usually does not produce person- ally but is good at making others in the group produce through “motivation” (Schmidt 2007, 53). Because German workers are in- nately self-motivated and often work hard for the good of the group, efforts to “motivate” them would be seen as
  • 23. unnecessary hand-holding and an in- sult to their professional pride. There- fore, German managers see little rea- son to learn about motivating or even supervising personnel. They assume work will be done well without any prodding (Schmidt 2007, 53). Overall, United States firms give management authority to make strategic decisions whereas German businesses see man- agers as less of a key factor to success. Differences between workforce education in Germany and the United States are consistent with the differ- ence in assignment of responsibility between GPK and United States cost center practices. A narrow focus in cost center manager responsibility in Germany facilitates well-defined spe- cific jobs for which young people can be trained. Because the United States workforce generally lacks such specific training, such well-defined jobs are not necessary to facilitate education. 50Spring 2010 • Vol. 25, No. 1 Portz and Lere The difference in education between German managers and United States managers is also consistent with differ- ences in the assignment of responsibil-
  • 24. ities between GPK and United States cost practices. United States managers tend to be educated to manage which implies a broader range of responsibili- ties including motivating while man- agement education tends to be very in- formal in Germany and therefore may not support as broad responsibilities. Cost Classification, Measures Used, and Cost Center Definition In order for managers under GPK to fulfill the responsibility of ensur- ing that changes in output levels are reflected in changes in costs, the man- agers must know which costs are ex- pected to respond to changes in output levels. Therefore, the GPK emphasis on classifying costs into proportional versus fixed identifies the costs that the managers can and are expected to con- trol, the proportional costs. Identifying proportional costs, those that change in proportion with cost center output, as opposed to vari- able costs, those that vary with some measure, also enhances the ability of GPK managers to fulfill their respon- sibility. Because the output measure for a cost center is chosen to relate to resource usage, the GPK concept of a proportional cost is more strongly tied to cause and effect than is the concept
  • 25. of a variable cost. While there may be a cause and effect relationship between a variable cost and cost center output, variable costs often have only a statisti- cal association with some measure that is often not cost center output. There- fore, the identification of proportional costs provides a GPK cost center man- ager with information on costs that he or she should be able to control as cost center output changes while identifi- cation of variable costs may or may not provide such information. The United States cost center man- ager, however, is typically responsible for managing the costs of a cost center in ways that include, but are not lim- ited to, the cost control responsibility of a GPK cost center manager. Iden- tification of variable costs as well as those costs identified under activity- based costing as changing with chang- es in the amount of unit-level activity, batch-level activity, or product-level activity is appropriate to support the broader responsibilities of a United States cost center manager. Because a cost center manager in the United States is responsible for controlling costs in a much wider variety of ways, he or she can potentially make use of a much broader set of measures. In addi- tion, the broader focus of a cost center in the United States may mean that
  • 26. the cost center does not have a single output measure. Therefore, multiple output measures may be appropriate in the United States. Cost centers with a narrow focus are necessary in order to assign responsibil- ity for ensuring that proportional costs change in response to changes in cost center output to GPK cost center man- agers. Only with a very narrow focus can a cost center’s operations be described using one output measure. This narrow focus explains the relatively small size of cost centers under GPK and their rela- tively large number per firm. The GPK practice of assigning mul- tiple cost centers to a manager likely arises because the GPK definition of a cost center leads to many, fairly small cost centers. If a unique manager was assigned to each cost center, a company would have an extremely large number of cost center managers, each with a fairly limited set of responsibilities. This would not seem to be an efficient use of resources. In the United States, the respon- sibilities of a cost center manager are typically broader than those under GPK. In order to make the types of decision typically made by a United States cost center manager, the cost center must be more broadly defined
  • 27. to allow for cost trade offs. This is con- sistent with the larger size of a typi- cal United States cost center and with the smaller number of cost centers in a typical United States firm. Discussion This section discusses cross-country differences in culture and education as potential explanations for cost center practice differences and offers impli- cations of these explanations. These implications are divided into ones of interest to managers considering im- plementing GPK and ones of interest to those considering future research. Implications for Managers When considering potential imple- mentation of GPK, it is important to consider both the types of decisions that a company wishes its managers to make and the possibility that culture and education differences between the United States and Germany may make GPK less effective in a United States company than in a German company. GPK cost center practices focus managers’ decisions primarily on cost reduction as a response to changes in cost center output. Therefore, it is im- portant for a company to consider the
  • 28. extent to which it wants managers to look for ways to reduce cost center cost 1. by reducing the cost center out- put, 2. by looking for tradeoffs among costs and 3. by considering other ways to reduce costs that are not related to changes in cost center output. Typical United States cost center practices are better designed to support decisions related to these types of cost reduction than are GPK practices. In addition, because culture and education differences imply different preferences and preparation for respon- sibilities, it is also important for firms considering implementing GPK cost center practices to consider if firm managers will be effective 1. with the narrower job focus and lim- ited ability to be involved in strategic or interdepartmental decision mak- ing under GPK and if the focus on narrow tasks will make 2. 51Spring 2010 • Vol. 25, No. 1 Portz and Lere managers feel too confined or even constrained from being creative.
  • 29. Suggestions for Future Research This article uses differences in cost center practices between the United States and Germany to explore pos- sible relationships between (1) culture and (2) education of the workforce and managers and managerial accounting practices. In doing so, it suggests sev- eral directions for further research. One direction for future research is to determine if the differences in cost center practices are related to differ- ences in culture, education, or both. An approach to answering this ques- tion would involve identifying Ger- man companies whose employees (1) are German, but have been educated in the United States, (2) are German and have been educated in Germany or (3) have been educated in Ger- many, but have spent substantial time in the United States. Comparisons of the cost center practices among com- panies whose employees fit in these three categories may shed light on the impact of each factor. Differences between German workforce and management education and workforce and management edu- cation in the United States are con- sistent with culture differences related to uncertainty avoidance (Hofstede
  • 30. 2001, 170). Therefore, another ques- tion of interest is whether differences in both cost center practices and edu- cation arise because of differences in country culture. Culture may be the main factor behind cost center practice differences directly and also indirectly through differences in the workforce and management education. References Chenhall, R. H. 2003.
