Portfolio management tools
Portfolio Management (PM) techniques are systematic ways of looking at a set of
projects or activities or even business units, in order to reach an optimum balance
between risks and returns, stability and growth, attractions and drawbacks in general,
by making the best use of usually limited resources.
Why and when are they used?
The motivation for a company to have several projects at a time can be of very
different nature. In many organizations, the uncertainty surrounding individual
projects leads them to place considerable emphasis on the development of a portfolio
of activities which is aimed to balancing risk and reward in such a way as to reduce
the overall uncertainty. One useful approach to this task is to consider the innovation
process from idea to implementation alongside certain variables, such as future cash
flow projections and resource requirements.
The starting point for this analysis is the recognition that the innovative process
within most organisations is likely to be a multi stage one which can be slowed down,
accelerated or discontinued as circumstances dictate. Some organisations consider
their portfolio as being similar to a funnel which they need to keep topping up in
order to ensure the flow through is strong enough and the outputs are sufficient to
meet their needs. Diagrammatically it might be portrayed as in figure 1.

In general, separate analysis of projects is unlikely to ensure the most productive use
of limited resources at any time, something which PM provides. Of particular
importance is also the need to ensure that RTD plans are consistent with business
strategy. Comparable problems of fit with strategy and selection of appropriate
investments within constraints are to be found in most aspects of business
management, and are commonly dealt with using PM techniques.
Several techniques dealing with PM can be mentioned. In general, all of them have
certain common aspects:
      •     A	
  portfolio	
  involves	
  balancing	
  the	
  results	
  of	
  assessing	
  the	
  individual	
  
            projects	
  which	
  comprise	
  it.	
  In	
  this	
  way	
  PM	
  could	
  be	
  combined	
  with	
  
            appropriate	
  single	
  project	
  evaluation	
  techniques.	
  In	
  fact,	
  when	
  used	
  to	
  
            assess	
  and	
  select	
  projects,	
  PM	
  partially	
  or	
  totally	
  uses	
  the	
  outcomes	
  of	
  the	
  
            analysis	
  undertaken	
  for	
  the	
  evaluation	
  of	
  individual	
  projects.	
  One	
  issue	
  to	
  
            be	
  dealt	
  with	
  when	
  applying	
  PM	
  is	
  that	
  projects	
  do	
  not	
  normally	
  occur	
  
            over	
  the	
  same	
  period	
  of	
  time,	
  which	
  imply	
  some	
  discontinuities.	
  In	
  fact,	
  
            having	
  the	
  timely	
  balance	
  of	
  projects	
  in	
  terms	
  of	
  costs	
  and	
  returns	
  over	
  
            time	
  is	
  one	
  of	
  the	
  typical	
  uses	
  of	
  PM.	
  	
  
      •     Every	
  project	
  should	
  be	
  examined	
  in	
  the	
  same	
  way,	
  in	
  order	
  so	
  ensure	
  the	
  
            consistency	
  and	
  validity	
  of	
  the	
  input	
  data.	
  Otherwise,	
  comparison,	
  
            hence	
  balancing,	
  between	
  projects	
  is	
  not	
  sufficiently	
  reliable.	
  A	
  common	
  
            vocabulary	
  has	
  to	
  be	
  established.	
  	
  
The level of analysis might differ to suit how the company organizes the RTD
activities. In that sense, although in the explanation of this tool it is often referred to a
portfolio of projects, in the same way, depending on specific techniques, the tool can
be applied to look at a set of programmes (which in themselves are made up of a set
of projects), or technologies, or even at different business units. In any case, one
important issue is that PM is in itself a strategic exercise used to look at the whole set
of RTD activities.

Many project evaluation techniques can in fact be used as portfolio evaluation
techniques, just by directly comparing the results of the assessment of individual
projects. On the other hand, there are other types of techniques specially suited for
PM, at the strategic and operational level. A classification of distinct types of PM
techniques is shown in table 1.

The techniques based on 2D and 3D matrices are considered the most interesting ones
for they are suitable for any company and context, as well as being quite easily
implementable and usable compared with other techniques. They are described in
more detail below.
These matrices provide a framework for examination of several parameters, and some
experimentation is needed by the company who wants to apply them in order to find
the appropriate combinations. These matrices, in any case, do not avoid the need for
judgement although these judgements will be well supported through the use of these
techniques.
2D and 3D matrices
These are matrices used to analyze and represent the situation of RTD projects or
activities, or even business units, according to 2 or 3 meaningful variables. All those
matrices are grouped together in this section because they can be regarded as mostly

complementary and require a similar process for analysing the data and for taking
decisions.
To analyze the portfolio, business and RTD managers first examine each individual
project, then place each project within portfolio structures (matrices) that
accommodate the strategic elements most critical to the specific company and its
industry.
In most cases, the qualitative nature of many of the human judgments necessary to
assess all variables implies that the projects can only be assessed on a relative rather
than an absolute basis (i.e. better or worse rather than correct or incorrect). In general,
preference is given to those variables easily understandable and of critical meaning to
the decision maker.
One common characteristic of the 3D matrices is that one of the variables usually
represent the size of the project measured in financial terms (eg the amount of funding
invested in a specific project or technology, or the revenues being generated by a
business unit). This factor stresses the importance given to the resource issue.
In what follows, several matrices are explained in terms of its specific objectives,
what they represent and the discussion they should imply. In general terms these
matrices are useful for projects, businesses, technologies and other kinds of
applications. The matrices shown are identified by the variables which are being
assessed and discussed

Use of the matrix
The matrix shows that efforts should better concentrate on those activities with high
probability of success and high expected value, although this is not always possible.
For those activities with low probability of success, an analysis should be made on
whether the expected return is worth the risk involved. In the example, project 1
should be better terminated and project 2 should be carefully analyzed. At the same
time, it is always interesting to have a pool of projects like project 4, which in total
ensure a steady stream of returns.

the portfolio of a company chiefly concerned to protect its position in existing
markets but, at the same time having two R&D projects (1 and 2) intended to gain
advantage, for instance through exploiting new technologies, one of which

compounds the risk by aiming at a new market. By drawing attention to this, the
evaluation will prompt discussion of the risks involved.
In summary, the company, while securing the position on current markets with
several projects, it is also aiming at new growth opportunities, either coming from
new markets or from strengthening the current position in new markets.

Use of the matrix
This matrix gives an understanding of the situation of a company's portfolio with
respect to technology and market. It is remarkable that both technology and market
are divided according to company's knowledge in three groups, and uncertainty
increases on those technologies and markets that are new. This matrix also gives
information about the risks involved (higher uncertainty, higher risks). Experience
says that those projects using unknown technologies and directed towards unknown
markets (projects 11 and 12) are likely to run into problems. On the other hand, if
successful, rewards might be huge.

Use of the matrix
The matrix describes the context for innovation activities. The circles might well
represent the size of business divisions and show that, while most divisions have
favourable strong technical positions, the new venture (project 1) is poorly placed in a
rapidly developing industry. It becomes clear that the position of this division will be
soon untenable, hence the strategy should be either to find an exit or to move it
upwards by receiving much stronger support. Projects 2 and 3 are reasonably well
placed while project 4 is close to an untenable low-profit situation and should
probably be terminated.

The matrix gives a view of the situation of a company's portfolio (products 1 to 14)

unknown the budget involved for a product or project increases in a great amount.
With the current portfolio the company is not probably securing its current position as
the budget devoted to key technologies is very distributed among a set of small
