BUILDING A RISK

TOLERANT IMS

Using Earned Value to manage the risk of a project in terms “risk adjusted physical performance”

Our Real Motivation is to Increase the Probability of Program Success PoPS

Page 3: Building a Risk Tolerant IMS

Risk Management is about Probability 3

Page 4: Building a Risk Tolerant IMS

Statistics v. Probability

In building our risk tolerant

IMS, we’re interested in the

probability of a successful

outcome “What is the probability of on

or before planned completion

date?”

The underlying statistics of

the cost, schedule and

technical performance

influence this probability.

The statistics of the task durations, their arrangement in a

network of tasks and correlation define how this probability

based estimated developed.

Identify Risks

Risk identification answers the question “What can

go wrong?” by:

Looking at current and proposed staffing, process,

technical, supplier, operational, resources, and any

other dependencies,

Monitoring technical results especially failures,

Reviewing potential shortfalls against expectations,

Analyzing negative trends.

Analyze Risks

Risk analysis answers the question “How big is the

risk?” by:

Considering the likelihood of the root cause occurrence;

Identifying the possible consequences in terms of

performance, schedule, and cost; and

Identifying the risk level using the “Risk Reporting

Matrix”

Planning the Risk Response

Risk mitigation planning answers the question “What is the program approach for addressing this potential unfavorable consequence?” One or more of these mitigation options may apply:

Avoiding risk by eliminating the root cause and/or the consequence,

Controlling the cause or consequence,

Transferring the risk, and/or

Assuming the level of risk and continuing on the current program plan.

Implementing the Risk Pln

Risk mitigation (plan) execution ensures successful risk

mitigation occurs. It answers the question “How can the

planned risk mitigation be implemented?” By:

Determining what planning, budget, and requirements and

contractual changes are needed,

Providing a coordination vehicle for management and other

stakeholders,

Directing the teams to execute the defined and approved

risk mitigation plans,

Outlining the risk reporting requirements for on-going

monitoring, and

Documenting the change history.

Tracking the Risk

Risk tracking ensures successful risk mitigation. It

answers the question “How are things going?” by:

Communicating risks to all affected stakeholders,

Monitoring risk mitigation plans,

Reviewing regular status updates,

Displaying risk management dynamics by tracking risk

status within the Risk Reporting Matrix, and

Alerting management as to when risk mitigation plans

should be implemented or adjusted.

Risk Control Processes 11

The control function takes the tracking status reports

for the watched and mitigated program risk and

decides what to do with them based on the

reported data. The general process of controlling

risks includes:

Analyzing the status reports

Deciding how to proceed

Executing the decisions

Connecting EV and Risk Management 13

EV data is assigned to Tasks and Work Packages,

managed by CAMs and WP managers.

They can review, prioritize, evaluate, classify the risks

they know well at the lowest level in the IMS.

In the planning stages of the IMS (or BoE), risks are

revealed during the normal course of work

Identifying and analyzing these risks, again falls on the

CAM and WP Managers.

During the Tracking activities, risks are including the

in standard EVM performance assessment

ETC, EAC, BCWR, and other going forward estimiates

Reference Class Step By Step From Nobel Prize to Project Management, Flyvbjerg, 2006

Page 32: Building a Risk Tolerant IMS

Flyvbjerg’s 4–step Approach 32

1) Form the reference class, a collection of similar-to projects for which there

is both history and reasonable insight to the history so that adjustments for

present time can be made.

2) Develop a true distribution of the reference class, and from that

distribution calculate the cumulative probability.

This probability curve, developed from reference class, the outside view.

3) Develop the inside view.

The inside view is a traditional estimate by the project team.

4) Adjust the inside view based on the probability of historical outcome from

the outside view.

Develop a forecast using the reference class probability confidence curve.

Pick a confidence limit, and then adjust the inside view to have a corresponding

confidence.

Summary

Earned Value methods used

to indicate risks

plan allocation of management reserve

track risk exposure “buydown”

track “buydown” investment

Use for “critical” risks

Account for actions that reduce risk

Fixing risks is cheaper than fixing problems
