Abstract: Our team is engaged in a study seeking to dev
elop a holistic framework for measuring the success of ERP
systems The rationale for our project is based on (1) the belief that “nobody invests in ERP systems solely
for the sake of improving business processes,” but to achieve better business results and (2) our finding that
there is a lack of consensus and clarity in the literature about how to define the success of ERP systems. As
part of this study, we analyzed an SAP implementation by a major international aircraft engine
manufacturing and service organization, and it revealed that ERP systems impact the business objectives of
the firm and the balanced scorecard approach can be adapted to build a holistic framework for identifying
success measures that link to company’s goals and strategies. This research-in-progress paper reports our
findings on balanced scorecard applicability for assessing the business contributions of ERP systems.
1 INTRODUCTION
ERP stands for Enterprise Resource Planning, and
the term is used for any software system designed to
support and automate the business processes of
medium and large businesses. The complexity of
implementing ERP systems is well noted and
analyzed in the literature [(Ahituv, Neumann &
Zviran, 2002), (Bhattacherjee, 2000), (Brown &
Vessey, 2001), (Markus & Tanis, 2000), (Markus,
Yanis & Fenema, 2000), (Scheer & Habermann,
2000), (Willcocks & Sykes, 2000)]. However, the
problem of assessing the benefits of ERP systems is
less well understood. Markus and Tanis (2000)
suggest that ERP success should consider the firm’s
motivations for implementing ERP systems and the
time period when the benefits are assessed. Shang
and Seddon (2000) suggest that there are different
types of ERP benefits that can be classified as IT
infrastructure benefits, operational benefits,
managerial benefits, strategic benefits and
organizational benefits. Rosemann & Wiese (1999)
and Rosemann (2001) suggest that the balanced
scorecard approach can be used to measure the
performance of ERP systems. They view the ERP
life cycle in terms of two phases, namely, ERP
implementation and ERP use, and they suggest
adapting the balanced scorecard dimensions to each
phase as an IT project. In summary, the key
learning from the ERP success literature is that ERP
benefits should be conducted at different points in
time and each assessment should reflect the benefits
to the timeframe under consideration.
The Balanced Scorecard, a technique developed
by
Kaplan & Norton (1996), is a powerful
framework for translating qualitative business
strategies into quantitative goals, and linking the
strategies and goals to internal organizational actions
via a robust set of key performance indicators.
Several researchers [Martisons et. al. (1999), Van
Grembergen & Van Bruggen (1997), Van
Grembergen, Saull & Haes (2003)] have suggested
that the balanced scorecard may help to evaluate the
performance of information systems (IS) and to
evaluate IT investments in a holistic manner.
Rosemann (2001) approach of defining an ERP
balanced scorecard does not directly connect with
the business goals and strategy of the organization
because the customers of the ERP system in their
approach are primarily the internal users of the
organization, the business processes are the IT
processes that support the implementation and
operation of the ERP system, and the business
objectives are the IT objectives for the ERP system.
Rosemann and Wiese assume that the cascading

the IT department level, to the organization level
will link the ERP balanced scorecard to the
organizational business objectives. We did not find
this to be a satisfactory approach to measure the
success of ERP systems. Instead, we decided to use
a case study approach to analyze successful ERP
implementations to study the impact of ERP systems
on the customers, business processes, financial and
the learning and innovation dimensions of the
organizational balanced scorecard. Thus, the
objective of this project is to develop frameworks
for aligning ERP implementations and operations
with strategic business objectives in a way that will
maximize the value-added contribution of ERP
systems to organizations.
We are just completing the pilot case study of an
engine manufacturing and service organization that
claims to be very successful in implementing the
first six phases of its SAP implementation in the last
three years. Our interviews with the IT managers
and business managers brought out sample measures
in all four categories of balanced scorecard that have
been positively impacted by their ERP
implementation thus far. The rest of this paper will
describe the SAP implementation and sample
organizational success measures that are positively
impacted by the SAP systems.
2 SAP IMPLEMENTATION
SAP is the dominant ERP vendor. SAP is both a
company, founded in 1972 and head quartered in
Walldorf, Germany, and software that automates
collaborative business processes for all types of
industries and for every major market. SAP is being
implemented in our case study organization using a
phased approach, with a four year planned roll-out
for each phase.
The goal of phase I was to demonstrate a quick
success, and develop a trusting working relationship
among the different SAP implementation partners. A
newly acquired engine service depot was selected as
the initial site for implementing SAP’s materials
requisition modules. This phase I implementation
ran smoothly using the standard implementation
methodology suggested by the business process
consulting partner.
In phase II the company made a decision to
implement the core financial models next. To avoid
customization of SAP code, the company adopted an
out-of-box implementation strategy with standard
configuration. The financial models were
implemented globally.
In phase III, the warehousing and parts tracking
modules in SAP were implemented. The inventory
tracking system is based on standard bar
codes/scanner technology.
In phase IV, the front-to-back supply chain was
automated at the initial site. In this phase, full order
processing, engine and parts management, labor and
material accounting, logistics, parts disposition and
invoicing modules were implemented.
In phase V, full project management of engine
production assembly was implemented in SAP. In
this phase, the process of receiving an engine, giving
it an overall inspection, tearing it down into
modules, inspecting the modules, repairing parts or
acquiring and replacing parts, and assembling,
testing and shipping the engine back to the customer
became paperless. This implementation also allowed
links with external suppliers via an Internet portal.
The goal of phase VI was to deploy the full
materials-requisition solution that was successfully
implemented at the initial site to engine center sites
2 and 3. The lessons learned in phase IV enabled a
very smooth deployment at the site 3 Engine Center.
The organization is now involved in deploying
the component repair modules of SAP in all other
globally located repair facilities.
3 SUCCESS MEASURES
The organization claims to be very happy with its
ERP implementation efforts and outcomes. When
we asked for specific measures that could illustrate
the success of ERP in our case organization,
company managers offered the following examples:
On time delivery of overhauled engines
improved from less than 50% to 95%;
On time delivery of spare parts improved from
30% to 90%;
The timeliness and availability of information
improved dramatically;
The reliability and integrity of data improved
noticeably;
Internal controls were tightened;
Work stoppages, caused by lack of parts on the
floor, dropped from several per month to an
average of one-half per month;
Enterprise-wide standardization of core finance
modules now provides the same financial
information to all the different stakeholders;
The inventory availability rates increased from
60-70% to 95%;
The cost of engine assembly process has been
significantly reduced;

The later phases of the ERP implementation
were executed better than the earlier phases;
The lessons learned from each phase are now
captured, documented and managed across the
enterprise;
Refined training methods are enabling users to
adapt to the system quickly and more
effectively, mostly due to the innovative
involvement of power users in the creation and
delivery of training;
Transfer of implementation process knowledge
from external consultants to company managers
was very effective.
It is interesting to note that these success
measures fall in one or more of the four categories
of balanced scorecard, as shown below:
Customer-Oriented measures
On time delivery of overhauled engines
On time delivery of spare parts
Business Process measures
Timeliness and availability of information
Reduction in work stoppages (Caused by lack of
parts on the floor)
Little or no business disruption when next ERP
phase goes live
Enterprise-wide standardization of the core
finance modules
Finance
Cost of inventory reduction
Cost of engine assembly process
Learning and Innovation
Later phases are better executed than earlier
phases
Capturing, documenting and managing the
lessons learned from each phase
Effectiveness of training in enabling users to
adapt to the system quickly
Early involvement of power users in the
creation and delivery of training
Knowledge transfer from external consultants
into the company
4 FINDINGS
Although these examples of success measures in the
four BSC categories suggest the applicability of
BSC to the ERP domain, they are quite incomplete
in the sense there are many more measures in each
of the four dimensions. In addition, the granularity
of these measures is uneven, and because a balanced
scorecard is not just a compilation of all the
measures it is not clear whether each of these
measures should be included in a balanced
scorecard. However, these measures demonstrate the
impact of the ERP system on the business objectives
of the firm as discussed below.
4.1 Impact on business objectives via
the business process category
In the engine service centers, the on-time delivery of
engines improved from less than 50% to between 95
to 100%. Similarly, in the engine assembly process,
work stoppages due to unavailability of parts
dropped from several stoppages per month to an
average of ½ per month. Also, the inventory is better
managed now with the on-hand-and-available rate
improving from 60-70% to 95%. In short, the ERP
system has drastically improved productivity and
has driven efficiency. Furthermore, the ability to
mine corporate data has led to improved human
resource planning, better investment spending and
higher quality decision-making
.
4.2 Impact on business objectives via
customer category
A common requirement in the engine manufacturing
and service business is ad hoc requests for a spare
part. This happens every time an airplane has engine
problem and local diagnostics reveal a part failure
that needs replacement. Prior to the deployment of
the ERP system, there was no way to directly track
and locate the exact warehouse in which the required
spare part is located, hence, customers had to call
each warehouse individually until the part was
located. This process took a significant amount of
time and the delay costs were considerable. Today
however, the ERP system shows every warehouse
where each spare part is located, and this allows the
customer to select and order delivery of the part
from the nearest warehouse, thus improving the
delivery time on spare parts. Similarly, the
implementation of the ERP system in the engine
service centers has streamlined the engine overhaul
process leading to improved engine turn-around time
to the customer. Thus the impact of process
efficiency in this case is improved customer
satisfaction.
4.3 Impact on business objectives via
finance category
The company also indicated that the cost of doing
business has been dramatically reduced. The

reduction of work stoppages, the timeliness of data
availability and better controls have improved
corporate performance and promoted labor
efficiencies. Also, better inventory and supply chain
management has resulted in decreased costs.
Simultaneously, the ability to make accurate
commitments to trading partners and improve turn-
around time has increased the after market business,
thereby resulting in increased revenues.
4.4 Impact on business objectives via
learning and innovation category
The end-user training process developed by the SAP
business process consultants relied on the standard
SAP business processes. The training materials
were narrative, documented in very thick books and
cumbersome. By phase III of the implementation,
the organization realized that the training process
was not effective because many interventions were
required to get the users become reasonably
proficient in using the new system. The organization
developed a new innovative training process that
required power users from each user groups to work
with the new system for 4 - 5 weeks and help
develop training materials for peers. A work-step
instruction book with 10 pages of PowerPoint slides
was developed for each module. Users were
allocated to appropriate training classes where they
sat in front of computer terminals in a classroom
facilitated by the power user on selected production
data to learn how to use the systems and its features.
This new training process has been very effective
and has replaced the old training process.
An example of learning and innovation in the
user domain involves the design and modification of
ERP input and output screen for the hourly workers.
Most of the hourly workers are not computer literate
and the multiple screen user interfaces of SAP were
challenging for these workers. The implementation
team developed simplified task-driven screens for
this audience.
5 CONCLUSION
This research-in-progress paper has illustrated that
ERP systems impact the business objectives of the
firm and, therefore, the balanced scorecard approach
can be used to assess the value and success of an
ERP system. We have now developed a holistic
business scorecard framework for identifying the
success measures for ERP systems. The details of
this framework will be reported in our next paper.
