There is agreement within the academia and practitioners that IT investments should be evaluated in order to
be in agreement with the overall strategic objectives of an organization. Moving toward to this direction, the
aim of this paper is to present a model that combines Balanced ScoreCard (BSC) methodology and a deci-
sion support method such as Analytic Network Process (ANP) for assisting the selection of an IT system.
The proposed model provides a simple, flexible and easy to use approach that can be applied by organiza-
tions to support their investment decisions. The proposed approach is presented through a case study for se-
lecting a Quality Management Information System for a large Greek retailer.
Keywords: Multi-Criteria Decision making, Balanced Scorecard, Analytic Network Process
Information system selection plays an important role in all
modern organizations since their smooth and efficient op-
eration depends heavily on Information Systems (IS). Fur-
thermore, large software systems are built by using com-
ponents developed by others (commercial or open source),
therefore an inc reasing need ap pears to se lect the righ t sys-
tem, the appropriate components in a systematic, factual,
objective, and cost efficient manner.
The selection process is far from being trivial since it has
to combine many, complex and in many cases contradict-
ing factors such as: business strategy, numerous functional
and non-functional requirements, operating priorities,
availability of resources etc. [1,2].
Traditional approaches and methods for selecting infor-
mation systems focus on well-known financial measures,
such as the Return On Investment (ROI) , Net Present
Value (NPV), the Internal Rate of Return (IRR), Cost/
Benefit Analysis (CBA) and the payback period [4,5].
However, these methods cannot offer the analytical power
needed for today’s complex decisions, since they fail in
quantifying intangible criteria.
Multi-criteria decision making (MCDM) can be quite
useful to support an IT system selection process. Although
there is no generic methodology that can be adopted for
selecting a soft ware packag e o f any type, liter atur e reviews
on evaluating software products suggest that users and de-
cision makers can receive a lot of support, if they decide to
adopt an MCDM method . In particular, the findings of
review studies [6,7] present that the Analytic Hierarchy
Process (AHP) has been widely and successfully used in
evaluating several types of software packages (e.g.,
MRP/ERP systems, simulation software, CAD/CASE sys-
tems, Knowledge Management systems etc.). The AHP
method was introduced by Saaty  and its primary objec-
tive is to classify a number of alternatives (e.g., a set of
candidate software packages) b y considering a given set of
qualitative and/or quantitative criteria, according to pair
wise comparisons/judgments provided by the decision
makers. AHP r esults in a hierarch ical lev eling of the se lec-
tion criteria, where the upper hierarchy level is the goal of
the decision process, the next level defines the selection
criteria which can be further subdivided into subcriteria at
lower hierarchy levels and, finally, the bottom level pre-
sents the alternative decisi ons to be evaluat ed.
A newer version of AHP is Analytic Network Process
(ANP) and is considered as a generic form of AHP. The
main difference between AHP and ANP is th at AHP struc-
tures a decision problem into levels forming a hierarchy,
while the ANP is using a network approach. ANP allows
both interaction and feedback within clusters of elements
(inner dependence) and between clusters (outer depend-
ence). Such feedback capture s the co mplex effec ts of inter-

play in co mplex situat ions in a better wa y, esp ecially when
risk and uncertainty are involved [9,10].
Nevertheless, the overall decision process should be fil-
tered in the context of business strategy. This can be ac-
complished with the application of Balanced Scorecard
Method (BSC). Not only being a methodology, BSC is
considered a performance measurement framework that
provides an integrated look at the business performance of
an organization by a set of both financial and non-financial
Obviously, the selection of the appropriate information
system can offer strategically, tactical and operational ad-
vantages to an organization. However, this selection is a
complex process that should be in line with the overall
strategy, take into account financial aspects and at the same
time be analytical.
In our paper, through the case study under investigation,
we present a model that starts at the high level with the
strategic objectives of an organization, as they have been
described by the use of BSC, and ends wi th the application
of ANP method, which quantifies and balances the low
The application of this model can greatly assist both the
high and mid level management in approaching the deci-
sion process from a different perspective, while at the same
time this decision is factual, consistent and well docu-
The structure of the paper is as follows, Section 2 pre-
sents the relevant literature background and an overview of
the employed methodologies. Section 3 presented the pro-
posed approach. In Section 4 we demonstrate the proposed
approach though the presentation of a case study. The case
study is focusing on the selection of a Quality Management
System (QMS) for a multinational food retail organization.
Conclusions and extensions of the research work are ad-
dressed in chapter 5.
2.1. Financial Methodologies for IS Selection
Traditionally, investment appraisal was based on finan-
cial accounting methodologies, such as return on invest-
ment and payback period. Their application has been
criticized as biased , since they tend to overlook
market status, human capital and process improvement,
growth opportunities etc. As such, they cannot measure
objectively past performance and forecast future out-
comes. However, financial indices are always considered
important since they measure the monetary value of the
Net Present Value (NPV) is defined as the total Pre-
sent Value (PV) of a time series of cash flows. It is a
standard method for using the time value of money to
appraise long-term projects . It is defined with the
where C0 defines the initial investment, Ct is the valua-
tion of the current cash flow and r is the discount rate.
Intuitively, NPV defines what would cost today a cash
flow that will take place in the future. In practical terms,
if NPV is positive then the investment adds value to the
business, the project is profitable and therefore the IT
system should be developed or purchased.
Similar to NPV’s measure is IRR (Internal Rate of Re-
turn), which is defined with the formula
Semantically, IRR is the calculation of the rate that
nullifies NPV . In case of selection between mutually
exclusive alternatives and especially when the initial co st
is different, incremental analysis shall be applied in o rder
to evaluate the IRR of the difference between two alter-
natives with the smaller cost . The reason behind the
application of incremental analysis lies to the fact that
IRR is measuring one single alternative.
Return of Investment (ROI), is a popular accounting
method for evaluating investments. ROI defines how
much an organization gets from the spent amount of
money. Therefore, ROI helps an organization to decide
on different investment alternatives. ROI is defined as
ROI investment t
and provides a comparison of the investment result ver-
sus the investment cost . Investment profit is defined
as the ex pec ted inco me min us the inve stmen t cos t, whe re
the investment cost is the initial cost plu s the cost during
the life-cycle of the project.
Finally, Payback Period (PP) is used to evaluate in-
vestments where the payback period of the investment
(the period needed to replenish the initial cost) is com-
pared to a predefined time period, the so-called cut-off
period. It is calculated by deducting the initial cost of an
investment from the financial benefits of the investment
throughout the def ined periods (months, years, etc.). E.g.
if the payback period is three years and the result of the
above mentioned operation on the third year (or earlier)
is bigger than zero, the investment must take place, oth-
erwise it must not.

problems that gained a lot of attention to be suppo rted by
AHP are: 1) prioritizing software requirements and 2)
selecting Component off the Self systems (COTS). In
both problems AHP has been used to compare software
requirements  or COTS products [16,17] by taking
into account the relative importance between value and
cost of each requirement/COTS product, respectively.
AHP is based on three basic conce pts (see Figure 1):

More specifically, a pair wise comparison takes place

be used, an AHP extension that handles both intra- and
inter-dependencies among clusters of selection criteria

d with four discrete perspec-
e is that a network is created i
hierarchy (see Figure 2), where there is no specific Goal
object but instead the sub-criteria of AHP stand as the
elements of the objects (clusters in ANP terminology).
Still, the main difference is the feedback, where the
evaluation of criteria with regard to alternatives is al-
lowed, against the top -down approach of AHP where the
importance of the alternatives is examined with regards
to criteria. The goal of selecting the best alternative is

versus the alternatives and vice versa.
has achieved wide publicity among both scientists and
managers. BSC is being widely accepted since it fills the
gap between the development of a strategy and its reali-
zation by supporting and linking critical management
processes . More specifically, it takes conventional
financial measures like ROI and payback period and
complements them with additional ones that reflect cus-
tomer satisfaction, internal business processes, and the
ability to learn and grow.
The above idea is modele

and 4) Learning & Growth dimensi ons (see Figure 3).
1) The Learning & Growth Perspective provides t
vers for achieving the objectives of the other three
areas of the scorecard. The key factors that constitute this
perspective are: employ capabilities, information system
capabilities and employee motivation, empowerment etc.

The problem the organization faces is the integration of
its strategic plan to a
rformance measurement and, as a consequence, will
propose measures (alternatives) to be taken to improve it
in terms of Information Systems.
Having in mind the pyramid of decision making levels
within the org anization (Figure 4), an integrated solution
is obvious to be required to provide added value and re-
usability to the organization. In our approach, in order to
support the decision process at the highest level, the ap-
plication of BSC is suggested, for defining the strategic
objectives and the necessary initiatives that the organiza-
tion has to take. For the middle level decision support,
ANP is used in order to assist the process of selecting the
most beneficial QM S.
To give an insight on the quality management process
within the org anizatio n, it is h an d led manu all y or with th e
use of ad-hoc applications developed locally at each dif-
ferent country of the multi-n ational company. The qu ality
management process includes quality controls, report
creation towards the top management and compliance
control against to quality standards.
The different threads of the quality process are pre-
sented in Figure 5. The complexity of this p rocess is sub-
stantial since it involves a large number of stakeholders, a
large number of quality controls and control points. Some
process statistics taken fo r a 4 years’ period are presented
in Table 1. The need is evident to merge multiple and
interlinked activities under a common IT platform of
managem ent and processing.
4.1. Developing the Scorecard
The first step of our approach was the development of
the strategy map for the organization under study. As
we already mentioned, the strategy map defines the

strategic objectives of the organization for every per-
spective of the balanced scorecard and interlinks these
objectives with cause-effect relations. The cause-effect
relations define a finish-to-start relationship between
objectives. Figure 6 presents the strategic map for the
organization. The arrow connections imply cause-
effect relation, e.g. Process Quality Assu
Improvement or that Service Quality A a
prerisite for Custtisfaction.
The second step of our method is the detefini-
tion e strategic objec-
tive will sed to
measure the performance related with the objective, its
scope, the measurement frequency (yearly, monthly), etc.
Additionally, in order to b e able to compare and quan-
titatively evaluate each objective, we need to assign a
weight to each goal within the perspective. A snapshot of
the detailed definition of some of the strategic ob jectives
is presented in Table 2. As it appears in the table, the
implementation of a QMS is the proposed strategic ini-
tiative for some objectives (CP2, CP3).
In order to calculate the priorities of the organiza-
tion’s strategy regarding the initiatives to take, we add
the products of the weights of every strategic objective
with the weight of the hosting perspective . E.g.
Process standardization, Process Quality Assurance
and Service Quality Assurance suggest QMS as the
preferred initiative to be undertaken. After doing these
calculations, we end up to a score of 39% for QMS as
the suggested strategic initiative. For all calculons,

As a last comment, what must be clear for BSC is
that it requires the participation of all the organization,
lead by a project team or in other cases the manage-
ment team, for all the steps mentioned above.

different vendors in a form of questionnaire and received
information from 10 vendors referring to 10 different

Consequently, one can progress the alternative B as

biggest ROI, as well as NPV and ROI. Still, this result
depends only on financial measures and is not taking into
consideration intangible criteria, such as functionality,
that are examined within the ANP framework.

to a higher control criterion. These comparisons produce
a priority vector for every cluster with regards to the
others and are used to weigh (multiply) the relative sub
matrices of the unweighted supermatrix. E.g. the first
value of this vector (first column, first row) is multiplied
with all the elements of the relative sub matrix of the
unweighted supermatrix, the second value (first column,
second row) with the sub matrix having as column the
cluster Alternatives and as row the Cost, etc.
The result of this process is the production of the
weighted or stochastic supermatrix (Table 11). The
transformation to a stochastic per column or simpler
stochastic comes out of the fact that the fina l priorities of
the elements have to meet some reduction and cyclicity
needs . As every column’s summation equals to one,
the intuitive reason is to present the priority of every
element throughout the network.
The weighted supermatrix is multiplied by itself until
the supermatrix’s row values converge to the same value
for each column of the matrix. The result is the limiting
supermatrix (Table 12). Its columns (normalized per
cluster) constitute the final priorities of the network, in-
Focusing to the alternatives sub-matrix, the alternative
that has the highest priority shall be chosen and for our
case study, System A shall be the proposed solution

all) score of System B, that was progressed by the finan-
cial methodologies. This can be explained by taking th

0% of the total network dependency, it gives a good
reason why Cost (and in general tangible criteria) does
not hold the major role in IS selection.
The purpose of this paper was to present a BSC-ANP
unified model for IS selection. Through its case study,
this model was ex ecuted for the selection of a QMS for a
multinational retail organization. It is the first time tha
such a mzation’s
trategy in total. Previous attempts were using ANP to
“evaluate” the importance of one BSC perspective over
the others for insurance or manufacturing organizations
[25,26], which is far from the main goal of this model.
Its basic principles support the execution of the or-
ganization’s strategy by approaching it in high level
when applying BSC and to a lower level when executing
NP in order to assist the selection problem that comes
ut as the proposed initiative from BSC. This is where
perational performance of the system se-
cted by ANP will then have to b e measured in terms of

reason why the financial methods fail to quantify intangi-

evaluation phase is another reason why ANP is a good
choice. In that way, resistance to change is significantly

gards to Alternatives is something that cannot happen in
AHP and clearly shows the limitations of this methodol-
gy. Still, its wide expansion in all kinds of problems
A decision criterion that the organization co
cal can be easily added while the selection problem is
ongoing. In that way, due to its general directives, the
use of the model can be validated for all kinds of organi-
zations and IS.
Enhancements can also be made in terms of monitor-
ing the performance of the BSC model. As each strategic
objective is monitored on a certain frequency, it would
be interesting to integrate an iterative process in the
model to measure the added value that came out of the
implementation of the selected QMS (System A) and its
“score” versus the relative strategic objectives (Figure 7).
Tools like the one used in this study can easily integrate
such processes through business intelligence techniques
to give the chance to top management to have a real-time
view on the strategy execution.

While we believe that the model presented provides
value, there are areas for future enhancements and vali-
dation. It is acknowledged that the decision levels in-
volved in any selection problem can vary, depending on
the organization. Indeed, this is one of the strengths of
ANP: the ability to adap t its framework to custom needs.
