making

Can risk analysis help?
3. Research on project failures
1994,World Bank issued the Wapenhans
Report on its overall project portfolio
(Infrastructure for Development). It
identified an increasing number of poorly
performing projects and concluded that
there were two main causes: over-
optimistic estimates of project viability
and inadequate attention to risk and
uncertainty.
4. 2013, National Audit Office identified that
the tendency for over-optimism, whether
unconsciously or deliberately, results in
the underestimation of time, costs and
risks to delivery and the over-estimation
of the benefits.
Research on project failures
5. 2014, PWC report ‘Portfolio and
Programme Global Survey’ summarises
regular themes from previous surveys.
One of the themes is estimating. In 2004
and 2007 the theme was bad estimates
while in 2012 and 2014 the focus was
again on the same issue namely, poor
estimating in the planning phase.
Research on project failures
6. 2015, Calleam study concluded that
there are 101 common causes of project
failure grouped into 13 major categories,
one of which is estimation. Two
examples are i) decisions are made on
singular values of duration and costs
rather than using a range of values that
reflect the risks and uncertainties in the
estimates for the forthcoming project
phase(s) and ii) there is a failure to build
in contingency to handle risks and
uncertainties.

7. Infrastructure examples
Cost Overruns of High Profile Projects (Source: Megaprojects and
Risk: An Anatomy of Ambition, Flyvbjerg, Bruzelius and
Rothengatter)
8. Two questions for project decision-
makers
How risky is this project?*
How do you know?*
Risk analysis may be able to help
answer these questions

9. Challenges for decision-makers
Will everything go according to plan?
What can blow the project off course?
Is the plan optimistic?
What are the governance arrangements?
Who is the sponsor?
Who are the stakeholders?
Is the funding secure over the project life cycle?
10. How good are the estimates?
Have they been independently verified or
tested as in reference class forecasting?
Have the assumptions been tested?
Have lessons learned from previous
projects been reviewed and taken into
account?
Do we have the resources (in house or
in the supply chain) to meet the
complexity of the project?
Challenges for decision-makers
11. Do we have the resources (in house or
in the supply chain) to meet the
complexity of the project?
How experienced are the decision-
makers in relation to the complexity of
the projects they are making judgments
on?
To what extent do the project promoters
present the project in such a way as to
get the business?
Challenges for decision-makers
13. The risk process (PRAM* Guide)
*PRAM = (Association of Project Management) Project Risk Analysis and Management
14. Risk analysis definitions
Qualitative – assessment of risk relating to the qualities and
subjective elements of the risk. Useful for understanding the
effect of individual risks and prioritisation
Quantitative – modeling of numerical outcomes by
combining values and relationships between values. Useful
for determining a range of likely outcomes, risk drivers,
planned effectiveness of risk responses and setting
contingency

19. Can risk analysis help?
Questions of any project:
– How risky is this project?*
– How do you know?*
Use quantitative analysis to answer first question
Use qualitative assessment to help answer the second
question
Risk analysis can help project decision makers by
alerting them to the probabilistic nature of projects
The ranges of time and cost could be used instead of
using a single value, to set a risk-adjusted baseline
A defensible contingency could be set based on risks and
uncertainties

Editor's Notes
Etc Etc alludes to How good are the estimates? Have they been independently verified or tested as in reference class forecasting? Have the assumptions been tested? Have lessons learned from previous projects been reviewed and taken into account? Do we have the resources (in house or in the supply chain) to meet the complexity of the project?
How experienced are the decision-makers in relation to the complexity of the projects they are making judgments on? To what extent do the project promoters present the project in such a way as to get the business?
Does this life cycle diagram imply a ‘production’ mode of thinking in which each phase of the cycle is totally predictable? Does this give the impression to the decision-makers that all is plain sailing no matter how complex or risky or uncertain the project? Do we need to conjure a non-linear picture of project phases? If the model is ok do we need to foster and encourage agile team makers who use their knowledge to manage risks proactively to reduce likelihood and / or impact?
