| Abstract: Project Portfolio Management (PPM) is a relatively new management disci-
pline which helps organizations to compose and manage their project portfolios.
Although PPM covers a much wider area more than project portfolio selection,
the latter will be the focus of this presentation. After all, the selection process
determines the investment decisions — and thus the future profitability — of
every organization. This awareness is also growing in business. Therefore, orga-
nizations are gradually taking steps to make their current selection procedures
more objective.
There is a wide variety of tools and techniques available to assist organiza-
tions with this activity. Tools and techniques for graphical representations and
financial models are the most frequently used. However, the complexity of this
decision problem demands the application of even more complex techniques be-
longing to the field of Multicriteria Decision Making (MCDM). These methods
provide the decision maker(s) not only with the possibility to incorporate multiple
criteria into the selection process, but allow in addition to model the preferences
of this decision maker in case of lacking information.
In this talk, we thoroughly compare three MCDM-techniques: Weighted Scor-
ing, The Analytical Hierarchy Process (AHP) and ARGUS. Since a ‘good’ selec-
tion method is user-friendly as well as methodologically correct, the conformance
of each of these methods with the following four parameters is examined: (1)
transparency, (2) ease of manipulation, (3) time required for execution and (4)
respect for scales.
Although user-friendliness is generally perceived as the most important fac-
tor to define the difference between a ‘good’ and a ‘bad’ selection method, this
presentation proves the importance of the methodological characteristics of the
method applied. A real case-example of a multi-criteria project selection study
executed at the Flemish Government illustrates that in case of disrespect of mea-
suring scales, one cannot state with certainty that the decision results are reliable
and not coincidental.
Although none of the tested methods for project portfolio selection dominates
the other, i.e. no method complies to all methodological and operational criteria,
we find that ARGUS represents the best compromise between these two worlds.
The abstraction of the ARGUS-algorithm makes manipulation rather difficult,
the availability of a user-friendly software shortens the time for execution signifi-
cantly and, even more importantly, it is the only method of three which respects
the ordinal scale of decision variables. However, due to the lack of transparency,
the acceptance of ARGUS in practice remains a big question mark.
