Project Risk Management Fundamentals: A Comprehensive Overview

 
Chapter VI: Quantitative Risk analysis
 
The goal of project risk management is to minimize potential risks while
maximizing potential opportunities.
Major processes include Risk management planning: deciding how to
approach and plan the risk management activities for the project
Risk identification:  
determining which risks are likely to affect a
project and documenting their characteristics
Qualitative risk analysis
: characterizing and analyzing risks and
prioritizing their effects on project objectives
Quantitative risk analysis:
 measuring the probability and
consequences of risks
Risk response planning
: taking steps to enhance opportunities and
reduce threats to meeting project objectives
Risk monitoring and control
: monitoring known risks, identifying new
risks, reducing risks, and evaluating the effectiveness of risk
reduction

Quantitative Risk Analysis
 
Assess the likelihood and impact of identified risks to determine
their magnitude and priority
Quantitative approaches to project risk analysis include
mathematical or statistical techniques that allow us to model a
particular risk situation. At the heart of many of these models is
the probability distribution. Probability distributions can be
continuous or discrete.

Top 10 Risk Item Tracking
 
Top 10 Risk Item Tracking is a tool for maintaining an
awareness of risk throughout the life of a project
Establish a periodic review of the top 10 project risk items
List the current ranking, previous ranking, number of times the
risk appears on the list over a period of time, and a summary
of progress made in resolving the risk item

Expert Judgment
 
Many organizations rely on the intuitive feelings and past
experience of experts to help identify potential project risks
Experts can categorize risks as high, medium, or low with or
without more sophisticated techniques

Quantitative risk analysis Often follows qualitative risk
analysis, but both can be done together or separately
Large, complex project involving leading edge technologies
often require extensive quantitative risk analysis
Main techniques include
Decision tree analysis
simulation
 
11
 
Decision Trees and Expected Monetary Value (EMV)
 
A decision tree is a diagramming method used to help you
select the best course of action in situations in which future
outcomes are uncertain
EMV is a type of decision tree where you calculate the
expected monetary value of a decision based on its risk event
probability and monetary value
 
12
 
Expected Monetary Value (EMV) Example
 
13
 
Simulation
 
Simulation uses a representation or model of a system to
analyze the expected behavior or performance of the system
Monte Carlo analysis simulates a model’s outcome many time
to provide a statistical distribution of the calculated results
To use a Monte Carlo simulation, you must have three
estimates (
most likely, pessimistic, and optimistic
) plus an
estimate of the likelihood of the estimate being between the
optimistic and most likely values

Risk Response Planning
 
After identifying and quantifying risk, you must decide
how to respond to them
Four main strategies:
Risk avoidance
: eliminating a specific threat or risk, usually
by eliminating its causes
Risk acceptance
: accepting the consequences should a risk
occur
Risk transference
:  shifting the consequence of a risk and
responsibility for its management to a third party
Risk mitigation
: reducing the impact of a risk event by
reducing the probability of its occurrence
 
17
 
General Risk Mitigation Strategies for Technical, Cost,
and Schedule Risks
 
18
 
Risk Response Control
 
Risk response control involves executing the risk management
processes and the risk management plan to respond to risk
events
Risks must be monitored based on defined milestones and
decisions made regarding risks and mitigation strategies
Sometimes workarounds or unplanned responses to risk events
are needed when there are no contingency plans
 
19

Various tools exist for monitoring and controlling project risk.
These include:
Risk Audits—A knowledgeable manager or group can be
useful for auditing 
the project team from time to time. The
audit should focus on ensuring that the project manager and
team have done a good job of identifying and analyzing
project risks and on ensuring that proper procedures and
processes are in place. Risk audits should be conducted by
people outside the project team. Using outsiders provides a
fresh perspective; the project team may be too close to the
project and miss significant threats or opportunities.
 
20
 
Cont …
 
Risk Reviews
—Risk audits should be conducted by individuals
outside the 
project team; but risk reviews can be conducted
internally. Throughout the project life cycle, the project
stakeholders should hold scheduled, periodic risk reviews.
These reviews should be part of each team meeting and part
of the project team's learning cycles.
Risk Status Reports
—Similar to risk reviews, a monitoring 
and
control system should provide a formal communication system
for monitoring and controlling project risks.
 
21
 
Using Software to Assist in Project Risk Management
 
Databases can keep track of risks.  Many IT departments have
issue tracking databases
Spreadsheets can aid in tracking and quantifying risks
More sophisticated risk management software, such as Monte
Carlo simulation tools, help in analyzing project risks
 
22
 
Results of Good Project Risk Management
 
Unlike crisis management, good project risk management
often goes unnoticed
Well-run projects appear to be almost effortless, but a lot of
work goes into running a project well
Project managers should strive to make their jobs look easy to
reflect the results of well-run projects
 
23
 
THREE ELEMENTS OF PROJECT RISK ANALYSIS
 
There are three basic concerns in project management:
1. Schedule. Will the project go over schedule?
2. Cost. Will the project overrun its budget?
3. Performance. Will the output satisfy the goal(s) of the project?
So by the  definition of risk in the previous chapter each of these
elements should be subjected to a risk analysis (preferably
quantitative) that will help project managers decide whether the
project is in jeopardy of not meeting its commitments and
whether or not to take action to mitigate the r
isk.
 
24
 
Cont …
 
What is schedule risk? It is the probability that a project will
overrun its schedule. Conceptually we would like to see an
analysis such as the following nominal graph of schedule risk
for an imaginary project:
 
25
 
Cont …
 
26
 
Cont …
 
If the deadline for the project is 42 months this analysis
indicates that the probability of completing the project in that
time is
80%. There is only a 50% chance of completion in 35 months,
and we are
virtually certain that the project will be completed in 70
months.
 
27
 
Cont …
 
For cost we would like to see a similar curve, with the
difference being that on the x-axis we would have cost at
completion rather than months to completion:
 
28
 
Cont …
 
29
 
Cont …
 
We expect these curves to be different at different stages of the
project; for example during the planning stages both curves
might have a less steep slope, indicating that there is
considerable uncertainty about the length of the project or its
total cost, i.e., there is larger probability of going past 70 months
in duration. As the project progresses the curves may shift in
either direction as events happen that increase or decrease
schedule or costs. And, as the project nears completion, the
curve should become steeper as we become more certain about
the final completion date and cost. These curves encapsulate
what we want in a risk assessment of cost and schedule.
 
30
 
Performance Risk
 
Unlike schedule and cost risk analysis, where the methodologies
are largely generic across all project types, methods of
performance risk analysis tend to be much more tightly 
tied to
subject area
. Further, quantifying the relationships between
different aspects of performance may be much more difficult.
 
31
 
Summary
 
Project risk management is the art and science of identifying,
analyzing, and responding to risk throughout the life of a project
and in the best interests of meeting project objectives
Main processes include:
Plan risk management
Identify risks
Perform qualitative risk analysis
Perform quantitative risk analysis
Plan risk responses
Control risks
 
32
 
Cont …
 
The project manager working with the project team and project
sponsors will ensure that risks are actively identified, analyzed, and
managed throughout the life of the project.  Risks will be identified as
early as possible in the project so as to minimize their impact.  The
steps for accomplishing this are outlined in the following sections.  The
<project manager or other designee> will serve as the Risk Manager for
this project.
Risk Identification
Risk identification will involve the project team, appropriate
stakeholders, and will include an evaluation of environmental factors,
organizational culture and the project management plan including the
project scope.  Careful attention will be given to the project
deliverables, assumptions, constraints, WBS, cost/effort estimates,
resource plan, and other key project documents.
A Risk Management Log will be generated and updated as needed and
will be stored electronically in the project library located.
 
33
 
Cont …
 
RISK ANALYSIS
All risks identified will be assessed to identify the range of
possible project outcomes.  Qualification will be used to
determine which risks are the top risks to pursue and respond to
and which risks can be ignored.
Qualitative Risk Analysis
The probability and impact of occurrence for each identified risk
will be assessed by the project manager, with input from the
project team using the following approach:
Probability
High  probability of occurrence
 
Greater than 
70%
 
34
 
Cont …
 
Medium – Between 
30% 
 and 
70%
 probability of occurrence
Low – Below 
30% 
 probability of occurrence
 
35
 
Cont …
 
Impact
High – Risk that has the potential to greatly impact project
cost, project schedule or performance
Medium – Risk that has the potential to slightly impact project
cost, project schedule or performance
Low – Risk that has relatively little impact on cost, schedule or
performance
 
36
 
Cont …
 
Quantitative Risk Analysis
Analysis of risk events that have been prioritized using the qualitative
risk analysis process and their affect on project activities will be
estimated, a numerical rating applied to each risk based on this
analysis, and then documented in this section of the risk management
plan.
Risk Response Planning
Each major risk (those falling in the Red & Yellow zones) will be
assigned to a project team member for monitoring purposes to ensure
that the risk will not “fall through the cracks”.
For each major risk, one of the following approaches will be selected
to address it:
Avoid
 – eliminate the threat by eliminating the cause
Mitigate
 – Identify ways to reduce the probability or the impact of the
risk
Accept
 – Nothing will be done
Transfer
 – Make another party responsible for the risk (buy insurance,
outsourcing, etc.)
 
37
 
Cont …
 
RISK MONITORING, CONTROLLING, AND
REPORTING
The level of risk on a project will be tracked, monitored and
reported throughout the project lifecycle.
A “Top 10 Risk List” will be maintained by the project team and
will be reported as a component of the project status reporting
process for this project.
All project change requests will be analyzed for their possible
impact to the project risks.
Management will be notified of important changes to risk status
as a component to the Executive Project Status Report.
