Abstract
The ever-increasing penetration of projects as a way to organise work in many organisations necessitates effective management of
multiple projects. This has resulted in a greater interest in the processes of project portfolio management (PPM), with more and
more software tools being developed to assist and automate the process. Much of the early work on PPM concentrated on the man-
agement of IT projects, largely from the perspective of the management of resources and risk. Many of the recent articles have been
by vendors of the software, promoting the value of the PPM process. However, the claims made in those articles are typically only
supported by anecdotal evidence. In this paper, we assess whether there is a correspondence between the use of PPM processes and
techniques, and improvements in the performance of projects and portfolios of projects. Based on our findings, we introduce a three-
stage classification scheme of PPM adoption, and present a strong correlation between (1) increasing adoption of PPM processes
and a reduction in project related problems, and (2) between PPM adoption and project performance.

manage IT projects in order to maximise their economic
benefits. Part of that challenge can be tackled by ‘‘doing
projects right’’ and part by ‘‘doing the right projects’’
[1]. While Project Management concentrates primarily
on the former, Project Portfolio Management, hereafter
referred to as PPM, is focussed on the latter. Contrary
to Project Management, which focuses on single project, and Programme Management, which concerns the man-
agement of a set of projects that are related by sharing a
common objective or client, or that are related through
interdependencies or common resources, PPM considers
the entire portfolio of projects a company is engaged in,
in order to make decisions in terms of which projects are
to be given priority, and which projects are to be added
to or removed from the portfolio (see also Lycett et al. [2]).
B.D. Reyck et al. / International Journal of Project Management 23 (2005) 524–537 525
PPM has largely developed around the following ele-
ments: providing a centralised view of all the projects in
an organisation, enabling a financial and risk analysis of
projects, modelling interdependencies between a family
of projects, incorporating constraints on resources
shared between projects, enabling prioritisation and selection of projects, ensuring accountability and gover-
nance at the portfolio level, allowing for portfolio opti-
misation and providing support in the form of
standardised processes and software tools.
However, despite the relatively extensive literature on
PPM (see Sections 2 and 3), evidence of its value has
been rather anecdotal. It is unclear whether there are
specific PPM elements that add more value than others or indeed, whether they add value at all. It is for these
reasons that we decided to investigate the potential for
increasing business value through the application of
PPM techniques to IT projects.
The first contribution of this paper is the develop-
ment of a classification scheme for the adoption level
of PPM across a diversity of organizations. Secondly,
we identify the impact of the PPM adoption level on project performance by investigating the correspon-
dence between the adoption level and reported project-
related problems on the one hand and observed positive
elements in projects on the other. Finally, we suggest a
phased implementation process for the adoption of
PPM and describe the challenges that organisations
might face in each phase.
The paper is organized as follows. Sections 2 and 3 contain a literature review of the theories, models and
processes presented for PPM, reviewed according to a
historic and a thematic perspective. The historic per-
spective provides a view of how the field has developed
over time, while the thematic perspective summarizes
the main themes identified in the literature. Section 4
describes the objectives and hypotheses of this study,
as well as the methodology used, with the general re- sults presented in Section 5. In Section 6, we present
a classification for adoption levels of PPM and in Sec-
tion 7 we investigate the impact of PPM and project
performance, highlighting the managerial implications
of this analysis. In Section 8, we provide a phased
implementation plan. Section 9 contains a summary
and our conclusions.
2. Literature review: a historic perspective
The field of portfolio management owes its origins to a
seminal paper written in 1952, in which Harry Markowitz
[3] laid down the basis for the Modern Portfolio Theory
(MPT). MPT allows to determine the specific mix of
investments generating the highest return for a given level of risk. Whereas MPT was initially developed for finan-
cial investments, in 1981, McFarlan [4] provided the basis
for the modern field of PPM for IT projects. According to
McFarlan, management should also employ a risk-based
approach to the selection and management of IT project
portfolios. He observed that risk-unbalanced portfolios
could lead an organization to suffer operational disrup-
tions, or leave gaps for competitors to step in. In 1992, Wheelwright and Clark [5] developed a
framework for categorising projects that they called
the Aggregate Project Plan. This plan allows for an
overview of the project portfolio along two dimensions,
(1) the extent of changes made to the product, and (2)
the degree of process change, leading to four categories
of projects (in increasing order of change): derivative
projects, platform projects, breakthrough projects and R&D projects (for complete definitions see [5]). This
framework can be used to identify gaps in the portfolio,
or potential resource shortages.
In the mid-1990s, the field of PPM received increasing
attention. In 1994, a GAO report [6] described a success-
ful company that used portfolio investment techniques
to manage its IT projects. The organisation developed
a set of criteria to evaluate benefits, costs and risks and thus determined the best mix of projects for obtain-
ing a better balance between maintenance and strategic
initiatives. As a result, in three years, the organization
reported a 14-fold increase in the return on investment
from IT projects.
In 1998, Thorp published the ‘‘Information Paradox’’
[7], putting PPM in a broader framework called ‘‘Benefits
Realization’’. According to the author, PPM techniques are fundamental for getting value from IT projects.
In a recent publication, Jeffery and Leliveld [8] report
the results of a survey with 130 senior executives, 90% of
whom were CIOs. The survey identified, among other
things, that 25% of the respondents could be defined
as optimally applying Information Technology Portfolio
Management (ITPM), 45% as having or adopting it and
78% as planning to have or to keep it.
3. Literature review: a thematic perspective
In this section, we review the main themes around
which research on PPM has been developed, namely
the PPM objectives and scope, the pre-conditions for
PPM, the key elements of PPM, the impact on organisa- tions and the problems within organizations associated
with a lack of PPM processes.
PPM objectives and scope. The majority of the litera-
ture in the PPM field provides similar lists of objectives
to be achieved through the adoption of PPM
approaches. Five main goals dominate the literature
[9–11], namely (1) defining goals and objectives, i.e.,
clearly articulating what the portfolio is expected to achieve, (2) understanding, accepting, and making
trade-offs, (3) identifying, eliminating, minimizing and
526 B.D. Reyck et al. / International Journal of Project Management 23 (2005) 524–537
diversifying risk, (4) monitoring portfolio performance,
i.e., understanding the progress that portfolio is making
towards the achievement of the goals and objectives,
and (5) establishing confidence in achieving a desired
objective.
Pre-conditions for PPM. Several papers discuss the pre-conditions that organisations should take into ac-
count, when adopting PPM approaches:
� Organisational strategy: Organisations should have clear strategic imperatives in place, properly commu-
nicated across all departments, to which the PPM
goals are to be aligned to [2]. Matheson and Mathe-
son [11], for example, describe a firm that designed a task force to develop a strategy for its lacklustre
R&D Portfolio, but soon found this to be in vain
since the company lacked a business strategy in the
first place.
� Business leaders� involvement: Another pre-condition for the adoption of PPM approaches is the involve-
ment of top executives who should be able to take a
less siloed view of the portfolio. As Kendall and Rollins [12] highlight, without the full understanding
and support of top executives the constant fight over
resources and reprioritisations will never be
resolved.
� Team skills: Another relevant aspect is the impor- tance of having a project team with relevant finance
and strategy skills. Although most IT professionals
have sufficient knowledge to calculate the net pres- ent value (NPV) or return on investment (ROI) of
a project, as Jeffery and Leliveld [8] noticed, to
build a proper business case for a project, the team
must understand the assumptions behind those cal-
culations, analyse the sensitivity of these results and
evaluate the risks that might impact project returns.
Key elements in PPM. Other papers discuss the key elements that constitute PPM:
� Centralised view of the project portfolio: Widely emphasised in the literature is the need for a centra-
lised view of the organisation�s projects [12]. The first step in the adoption of PPM approaches requires the
preparation of an inventory of current and proposed
projects, preferably through a central area responsi- ble for collecting, analysing and distributing project
information in a common format.
� Financial Analysis: While finance professionals have worked for decades with metrics to capture return
and risk of assets, the use of these methods for IT
projects still seems uncommon for many organisa-
tions [8]. Nonetheless, several techniques have been
created to properly measure the financial value of projects (see Benaroch [13], and McGrath and
MacMillan [14]). Most importantly, however, one
should choose a valuation methodology, be it return
on investment (ROI), internal rate of return (IRR),
net present value (NPV) or economic value added
(EVA), and consistently apply it.
� Risk analysis: McFarlan, [4, p. 142], noted that two of the main reasons for project failure were ‘‘the failure to assess individual project risk and the failure to con-
sider the aggregate risk of the portfolio of projects’’.
In addition, as observed by Markowitz [3], a portfolio
should not be chosen considering only individual
characteristics of the investments, but it should be
built based on the overall risk and reward of the port-
folio. When investment interactions are considered,
one can create portfolios with the same expected return but lower risk than when not taking into
account the interactions.
� Interdependencies: Thorp [7] noticed that one advan- tage of PPM is its ability to reduce inter-program
competition for resources and to turn program over-
laps into productive interdependencies. He identified
the following types of interdependencies: sequential
dependencies, overlapping outcomes, competition for scarce resources, and change bottlenecks.
� Prioritisation, alignment and selection: The selection of projects to compose a portfolio should ensure that
all areas of the organisation�s strategy are properly addressed and that the portfolio is well balanced
[15]. When properly combining portfolio alignment
and balance, organisations should come up with a
very clear picture of which projects should be cut off and which ones should be funded.
� Constraints: Goldman [15] highlights that incorporat- ing constraints is a key step in the portfolio alignment
process. Four types of constraints should be man-
aged: scarce human resources, staff capabilities, bud-
gets and infrastructure.
� Dynamic re-assessment of the portfolio: Jeffery and Leliveld [8] mention that only 26% of the respondents in their survey track financial measures after an
investment is made. As a result, managers ignore
options embedded in the portfolio, which would have
allowed them either to abandon unprofitable projects
before further investments are made, or to expand
successful investments.
� Need for specialized software: The need for special- ized software for PPM is a controversial issue in the literature. Some believe that there is no need
at all, whereas others claim that besides working
as a process change catalyst, specialised software
is indispensable due to the time consuming process
of updating all information needed for the decision
making process. Due to the growing number of
available software tools, several reports have been
issued that evaluate the best software available in the market according to several dimensions (see
e.g. [16]).
B.D. Reyck et al. / International Journal of Project Management 23 (2005) 524–537 527
Impact on organisations. Datz [17] provides a sum-
mary of the main benefits organisations should expect
from adopting PPM approaches. These include: (1)
maximizing the value of IT investments while minimiz- ing risk, (2) improving communication and alignment
between IT and business leaders, and (3) encouraging
business leaders to act as team players, allowing plan-
ners to allocate resources more efficiently and to termi-
nate projects.
Problems within organisations. Kendall and Rollins
[12] list four generic problems associated with a lack
of PPM processes and tools: (1) too many active pro- jects, (2) projects that do not add value, (3) projects
not linked to strategic goals, and (4) an unbalanced
portfolio. Other typical problems [18] include a lack
of coordination between projects, conflicting project
objectives, unexpected resource bottlenecks, late deliv-
ery of projects, lack of commitment from business
leaders, lack of cross-functional working, disappoint-
ment with final project benefits, and resistance to organisational change.
4. Methodology and hypotheses
There seems to be an agreement among experts that
organisations are in different stages of the adoption of
PPM approaches, even when organisations do not
explicitly and formally adopt them. Berinato [19] be-
lieves that there are 5 levels of PPM adoption from
the simplest to the more complex:
1. Put all projects in one database.
2. Prioritise the projects in the database.
3. Divide the projects into two or three budgets based
on type of investment.
4. Automate the repository.
5. Apply Modern Portfolio Theory.
Yet, according to the same author, benefits could be achieved at every level. At level 1, for example, the pro-
ject overview allows spotting redundancies. At level 2,
prioritization allows for an improvement in the relation-
ship between business leaders and IT people, since the
projects are seen as investments with economic value.
At level 3, by separating projects by type, organisations
can apply a more appropriate set of criteria to each type
of investments, facilitating the prioritisation and selec- tion process. At level 4, one of the main benefits is to en-
sure that information will be updated when needed
without people spending too much time collecting it. Fi-
nally, level 5 provides a better balance between risk and
reward.
Jeffery and Leliveld [8] propose a similar framework
comprised of three stages:
1. Defined: Organisations in this stage have defined
and documented the key components of the IT
portfolio and have high-level estimates of costs
and benefits for each element. The IT depart-
ment prioritises projects and has central budget
oversight. 2. Managed: Organisations in this stage have periodic
portfolio reviews with quantified and financial invest-
ment measures. Project data is codified and logged in
a central database. New initiatives are screened, cate-
gorised and prioritised.
3. Optimised: Organisation in this stage distinguish
themselves by the ability to balance and optimise
their IT project portfolio. They are disciplined in get- ting feedback from business leaders and use financial
valuation techniques such as Real Option Analysis
(for full definition see [20] and [21]).
Based on a survey, we developed a new framework
of PPM adoption and identified groups of organisa-
tions at different stages of the adoption of PPM. We
also correlated the PPM adoption level to the benefits the organisations perceived and to the level of prob-
lems they face in managing their projects. We used
an approach similar to the one adopted by Ibbs and
Regato [22], who showed that there is a positive rela-
tion between the level of adoption of project manage-
ment techniques and improvements in cost and
schedule performance in projects. We extended this
methodology to PPM. The aim of the research is to investigate the extent to which organisations view
their internal projects as discrete projects or as a
coherent portfolio of investments, and the value they
get from taking this perspective. We examined two
hypotheses:
Hypothesis 1. The adoption level of PPM processes and
techniques varies across organisations, allowing for
classification of organisations according to their level
of adoption. In addition, the PPM processes and
techniques adopted by organisations having a higher
adoption level are supersets in that they comprise the
processes and techniques also adopted by organisations
in lower categories, but also include more enhanced processes and methods.
Hypothesis 2. Higher adoption levels of PPM methods
and techniques result in fewer project related problems,
and increased value gained from information technology
projects.
In order to test the hypotheses stated above we de-
signed a survey with 5 sections. Section 1 collects
demographic information from the respondents. Sec-
tion 2 is designed to solicit information about the
PPM adoption level of each organisation, and is devel-
oped around the main elements that are part of the
528 B.D. Reyck et al. / International Journal of Project Management 23 (2005) 524–537
PPM approach, namely a centralised view of projects,
financial analysis, risk analysis, interdependencies,
constraints, overall analysis at portfolio level, prioriti-
sation, selection, accountability and governance, opti-
misation and specialized software. The majority of
the questions in this section were closed questions with a scale from 1 (‘‘don�t have any or don�t plan to have’’) to 5 (‘‘Always use’’). Section 3 provides respondents
with a set of issues commonly identified in the litera-
ture as associated to the lack of PPM. The scale
adopted is the same as Section 2 (1–5 scale with 1
being ‘‘not at all’’ and 5 being ‘‘to a great extent’’).
Section 4 provides respondents with a list of PPM ap-
proaches with a question whether they had imple- mented them and if yes, what had been the impact in
their organisation. The scale used in this section to rep-
resent a negative vs. positive impact is from �2 (‘‘sig- nificant negative impact’’) to +2 (‘‘Significant positive
impact’’), with two extra options ‘‘do not use’’ and
‘‘use but too early to assess’’. The questions in Sections
3 and 4 serve as proxies for the return on investment of
the projects in the IT portfolio, where we expect to see a negative correlation between the PPM adoption level
and the problems experienced, and a positive correla-
tion between the adoption level and the positive effects
observed. Finally, Section 5 solicits the challenges that
companies faced in the implementation of PPM. Here
a 1–5 scale is used, 1 representing ‘‘not at all’’ and 5
‘‘to a great extent’’. Note that since the survey is self-
assessment based, the results are subjective, which may affect the validity of the analysis and conclusions.
See Appendix A for a small sample of the survey ques-
tions. The full survey is available upon request.
An online survey was sent to 125 companies, either
through existing contacts or via existing agreements 3 .
Of these, we received 31 responses, a response rate of
25%. In addition, a mass mailing of 350 emails was
sent to IT departments within public organisations. In this case the response rate was disappointing, since
only 3 responses came from this source, a 1% response
rate, probably due to the fact that the survey never
reached an appropriate person in the organisation.
Our results therefore focus on the sample obtained
from the 125 companies with which we already had
contacts.
The sample includes medium and big organisations with turnover varying from less than £100 million
(19%) to more than £15 billion (4%). The number of
employees varies from less than 1500 (21%) to more
than 100,000 (6%). The majority of the respondents
are from the IT sector (55%), with others from Business

branch of the Association for Project Management. For details of their
activities see www.impact-sharing.com and www.apm.org.uk
respectively.
Operations (15%), General Management (15%), Strat-
egy (12%) and Finance (3%). Geographically, the
respondents are predominantly from the UK (40%),
with Europe accounting for 15% and the rest of the
world for 45%.
Using the terminology of Turner and Cochrane [23], we can classify the majority of projects these firms are
engaged in as either type 2 or type 3 projects.
5. Adoption of PPM processes: key results
Our main findings in terms of PPM adoption include
the following: Centralised view. The vast majority of the respon-
dents have a centralised view of its projects and have a
central point responsible for collecting, analysing and
distributing information:
� 93% have an inventory of current and proposed sig- nificant projects and 100% of the organisations that
do not have it plan to have it in the future; � 79% claim that they have a central point responsible for collecting, analysing and distributing information
regarding the portfolio of projects and 71% of the
organisations that do not have one plan to have in
the future.
Financial analysis. Our research identified that almost
all respondents use at least one technique to calculate the financial worth of its projects, with Payback being
the most common (93% ) and EVA the least common
(31%).
Risk analysis. The results of our survey show that the
complexity of projects and technological risks are the
main types of risks monitored by most organisations:
� Approximately 92% evaluate the complexity of pro- jects, including technology risks, cash flow and
organisational changes.
� Approximately 80% evaluate team expertise, market and environmental risks and management
commitment.
� 83% who do not evaluate team expertise intend to do so in the future and 80% who do not evaluate envi-
ronmental risks intend to do so in the future.
Interdependencies. We found that 84% of the respon-
dents take into account project interdependencies. 85%
look at cross-project dependencies while 82% considers
implementation bottlenecks.
Constraints at portfolio level. Among the firms sur-
veyed, budget and financial constraints are widely and
frequently taken into account, 91% of the respondents consider them, including 83% who observe them fre-
quently or always. We also noted that 100% of the

respondents who do not yet consider these constraints,
plan to do so in the future.
Overall analysis at portfolio level. Our research identi-
fied that an overall analysis at the portfolio level is not
widely implemented. Only 33% confirm examining
diversification to reduce portfolio risk, while 59% ana-
lyse risk-reward at the portfolio level; Categorisation, selection accountability and gover-
nance. The results show that the categorisation of pro-
jects does not seem to be a common practice among
respondents; 47% use categorisation to balance project
mix. On the other hand, accountability and strategic
alignment seems to be high and increasing; about
82% align the project portfolio with the organisation�s strategy and IT architecture, and consider the cus- tomer impact of project portfolio results.
Specialized software. Only 30% of the respondents use
specialized software to manage their portfolio of pro-
jects; of those who do not use any, 67% intend to use
in the future.
The survey results for Section 2 of the survey (PPM
adoption) are summarized in Table 1.
6. A classification on the adoption of project portfolio management
We grouped the organisations with different levels
of PPM adoption using cluster analysis, a multivariate
statistical methodology that classifies elements into rel-
atively homogenous groups, minimizing the variance
in use of PPM approaches within the groups and
maximizing the variance across the groups. Using SPSS, a k-means cluster analysis with Ward�s method [24] was performed. As the solution depends on the
Table 2
Adoption level analysis per stage

Centralisation of
project control
Most organisations have an
inventory of projects and
frequently use it, but project
control is largely decentralised
Frequently have a central point
responsible for collecting, analysing
and distributing project information
in a common format
Almost always have a central point
to control projects, which is
extensively used
Financial analysis Some financial analysis is
undertaken with special attention
to Payback Period and ROI
Financial tools are frequently used to
evaluate projects. The most utilised
are ROI, Payback period, NPV and
IRR
The financial analysis is always
done. Several tools are frequently
used
Risk analysis Occasionally risks are evaluated.
In most cases the attentions is in
financing/cash flow risks
All aspects of risks are to some extent
considered. Most of the focus is in the
complexity of the project and
technology risk
An extensive risk analysis is
performed. Attention is devoted to
project complexity, technological
risks, team experience and cash
flow risks
Interdependencies Some consideration of overlaps
and duplication of project results
Cross-project dependencies and
implementation bottlenecks are
frequently considered
Interdependencies are frequently
managed. Significant attention
given to cross-project dependencies
Constraints Little constraint analysis. The
only exception is the control of
the budget/financial capacity
Frequently evaluate budget/financial
capacity and competition for scarce
resources. Other constraints, such as,
staff capabilities to implement
projects are occasionally evaluated
Budget/financial capacity
constraints are always evaluated.
Other aspects such as staff
capabilities and competition for
scarce resources are frequently
managed
Overall portfolio
analysis
Very little analysis at the
portfolio level
More concern about portfolio
analysis. The portfolio financial
analysis is frequently managed and
risk vs. reward evaluation is
occasionally undertaken
Almost always the portfolio is
evaluated in terms of overall risk
and financial value. Frequently
portfolio diversification is
considered
Categorisation,
selection,
accountability
and
governance
Occasionally have top
management involved in project
selection. Also some effort is
spent in aligning the project
portfolio to the organisation�s strategy
More attention is devoted to the
project portfolio alignment to
strategy and IT structure. Also, there
is frequent involvement of top
management in the project selection
process
Significant alignment of the
portfolio to the organisation�s strategy. Systematic review of
projects at specific stages. Top
management frequently involved in
the project selection process and
business leaders are accountable
for project results
Optimisation Very few processes to optimise
the portfolio are in place. Some
effort is spent in generating
regular project portfolio
reporting
Frequently have regular project
portfolio reporting and annually, or
more frequently, the overall project
portfolio is prioritised
In general, processes to optimise
the portfolio are frequently
applied. Project outcomes are
always compared with the original
targets and project benefits are
frequently centrally tracked
Specialised software Not used Occasionally use specialised software
to manage the project portfolio
Use is more frequent than in the
Stage II, but it is still occasionally
employed
Overall adoption

situation. Hence, survey answers ‘‘do not use and do not plan to use’’
and ‘‘do not use but plan to use’’ represent the same current level ‘‘do
not use’’.

of PPM elements for each cluster was quantified by
averaging the respondents� scores to all questions. See Appendix B for the detailed scores. After having
defined the groups and quantified their level of use
of PPM techniques, we studied each group in order
to understand how they differ from each other. The
conclusions appear in Table 2 below.
7. The impact of project portfolio management
Once groups were identified and scores quantified, an
analysis of the impact of different levels of adoption of
PPM in organisations was performed.
Level of adoption vs. organisational impact. To verify
that the incremental use of PPM methods has a positive impact in organisations, we studied each groups� an- swers to the questions in the survey�s fourth section and compared them to groups� average levels of adop- tion of PPM previously identified in the cluster analysis.
Fig. 1 clearly demonstrates a significant positive rela-
tionship between the level of adoption and the impact
generated.
Four aspects appeared to most organisations as factors of greatest positive impact. First, the return
of what should be the first step of any PPM imple-
mentation was extremely valued by almost all respon-
dents: 90% of the managers who maintain an
inventory of projects claimed that the practice has
been responsible for a positive impact. Second, 88%
of the respondents who align the project portfolio to
a clear statement of the organisation�s objective said that this process has positively impacted their organi-
sation. Among those 52% noted a significant positive
impact. Third, the consolidation of information about
projects and the standardization of project analysis
improved the performance of 89% of the respondents
that implemented it. Fourth and finally, among the
organisations that explicitly considered project interde-
pendencies, 86% of them stressed the positive return
obtained by the process, with 43% claiming significant
success.
Level of adoption vs. level of problems with projects. We also identified the relationship between the use of
PPM processes and the level of problems associated
with the lack of PPM approaches in organisations. Sec-
tion 3 of the survey was used to calculate the groups� averages level of problems and again a strong relation-
ship, this time negative, between the use of PPM tech-
niques and level of problems was identified, as can be
seen in Fig. 2. The analysis of the three clusters identified in our
study showed that the groups were not only different in
terms of number of PPM elements adopted but also in
the intensity in which those were used. Also, the study
of how the use of PPM has impacted organisations and
changed the level of project related problems allows
answering our second hypothesis. First, the results show
that organisations, in general, see projects collectively and apply portfolio management processes. However,
they adopt these methods with different intensities.
Organisations at stage I, for example, scored 1.22 in
the survey sub-section related to analysis at portfolio le-
vel while respondents at stages II and III scored 2.03 and
3.37, respectively. Second, it is clear that the return from
PPM methods is reduced when some PPM approaches
are not adopted. As Fig. 1 shows, organisations at stage I obtained less impact from the implementation of PPM
elements (0.13 in a scale from �1 to 1), than stage II (0.28) or stage III (0.58) organisations. This means that
as organisations increasingly adopt PPM approaches,
the impact is strengthened. Third, the use of PPM tech-
niques not only positively impacts organisations but also
reduces the level of project related problems. As Fig. 2
shows, organisations at stage I found a significantly higher (0.80) level of problems than stage II (0.70) and
stage III (0.53) organisations. Fig. 3 provides an addi-
tional perspective on the difference between the stages
by mapping the main project issues, and their degree of
severity, to the different adoption stages.

8. A phased implementation plan for PPM
Based on the different PPM adoption stages and the
resulting benefits, we have developed a phased imple-
mentation plan for PPM. This plan is centred around the elements having the biggest impact in organisa-
tions in each stage, the issues managers currently face,
and the challenges these organisations face while
implementing these PPM processes. We elaborate on
the proposed three-stage PPM implementation plan
below.
8.1. Stage I: portfolio inventory
In this stage, the following PPM processes are to be
installed:
� Centralised project administration. � Risk evaluation procedures. � Explicit incorporation of resource constraints. � Increasing business leaders� accountability for project results.
Our study indicated that the greatest positive impact
of PPM can be observed when organisations start to (a)
assess economic and technological risks at the portfolio
level, (b) incorporate resource constraints in their deci-
sion making, and (c) explicitly look for risk diversifica-
tion across the portfolio. Nevertheless, according to our respondents, such organisations still face issues in
terms of lack of commitment from business leaders, lack
of alignment of projects to strategy, lack of coordination
between projects and conflicting project objectives.
Therefore, it was not a surprise to identify that, accord-
ing to the managers of these organisations, one of the
greatest challenges to advance the implementation of
PPM is the lack of a clear company strategy. They also
understand that their teams typically lack relevant train-
ing and appropriate knowledge to measure projects ben-
efits, which can explain the low impact of PPM in improving their assessment of financial worth of the
project portfolio.
8.2. Stage II: portfolio administration
In this stage, the following PPM processes are to be
installed:
� Project categorisation. � Evaluation of customer impact of the project portfo- lio results.
Organisations at this stage have better defined objec-
tives and are better informed about the costs and bene-
fits of their projects. Two aspects are especially
important for creating additional benefits from PPM, namely (1) processes to categorise projects and (2) better
evaluation of customer impact of the project portfolio
results. However, a large part of respondents of this
group also said that they lack resources to analyse pro-
ject data, suffered from people and financial constraints
as well as an overload of projects.
As organisations evolved from stage I to II, they still
encounter the same level of problems with excessive number of projects and people constraints, as seen in
Fig. 4. These organisations also cited lack of resources,
lack of appropriate ways of measuring project benefits
and high staff turnover as the main challenges to further
implement PPM.

8.3. Stage III: portfolio optimisation
In this stage, the following PPM processes are to be
installed:
� A project portfolio committee. � Assessment of the financial worth of the portfolio. � Management of project interdependencies. � Tracking project benefits.
The most optimistic findings came from stage III
organizations. The respondents in this stage claimed
that almost all aspects of PPM had significantly in-
creased the return on investment in projects. Among
the top of the list it is observed the importance of a
project portfolio committee. 45% of these companies have a committee composed by top management and
56% composed of senior general management. This
stresses the importance of top executives managing
the portfolio. Also, 89% of these committees meet at
least once a month.
Moreover, it is relevant to notice how strongly these
organisations think about investments at the portfolio
level. Respondents at this stage devoted high importance to the management of project interdependencies, align-
ment of the project portfolio with the organisation�s objectives and assessment of the financial worth of the
portfolio. Interestingly, this group was the only one that
obtained a fair return from the effort of the use of PPM
software. This reinforces the thesis that the use of PPM
software is only justifiable when the other aspects of
PPM are already in place. Although the level of project-related problems for
organisations in this stage is typically lower than at
other stages, managers of organisations at stage III said
that they still have problems with people and financial
constraints and late delivery of projects that are corre-
lated with high number of changes in project scope
and lack of cross-functional communication and work,
as highlighted in Fig. 4 above.
9. Conclusions
Based on a survey of 34 medium-to large-size com-
panies from the UK, Europe and the rest of the
world, we developed a framework for the adoption
of Project Portfolio Management (PPM) processes at
organisations. Using a cluster analysis, we identified
three stages of PPM adoption, and investigated which of the elements of PPM are typically present in the
organisations at the different adoption levels, including
a centralised view of projects, financial analysis, risk
analysis, managing interdependencies, incorporating
constraints, enabling an overall analysis at portfolio
level, project prioritisation and selection, and the use
of specialized software tools.
We correlated the PPM adoption level to the benefits the organisations perceived and to the level of problems
they face in managing their projects, and showed that an
increased PPM adoption level has a significant positive
impact on the return on the projects in the portfolio,
and a significant negative impact on the number of pro-
ject-related problems reported.
We also provide a phased implementation plan
for organisations to evolve through three stages of PPM adoption: from Portfolio Inventory through
Portfolio Administration to Portfolio Optimisation
534 B.D. Reyck et al. / International Journal of Project Management 23 (2005) 524–537
with increasing positive impact, both reducing the
organisational problems associated with projects and
enhancing return on investment. However, we have
also shown that organisations do not have to imple-
ment all the elements of PPM to create benefits. Even
organisations at stage I benefited from the few PPM elements they had implemented. According to our
Section 2: Projects and portfolio management in your organ
Section 3: Issues associated with projects
Appendix A. Sample of survey questions
results, value could be enhanced by properly choosing
the right elements to adopt. For example, our results
showed that implementing specialised project portfolio
management software will not add any value unless all
other major processes have also been adopted, and
therefore only make sense for organisations at stage III of PPM adoption.
