1Managing Risks in ProjectsMT 246 - Module 13
2Last Lecture Cost Estimating and Budgeting
- Estimating Process
- takes place at proposal time
- time phasing and bottom line totals
- direct labor
- direct material
- Overhead, G A, and Profit applied to totals
- final iteration at negotiation of contract
- Budgeting Process
- estimates at time of contract signature become
budget for remainder of program - updated and reforecast throughout life of
contract
3Risk Concepts
- The Likelihood that some Problematical Event will
Occur - The Impact of the Event if it does Occur
- Risk f (likelihood, impact)
- Project is considered Risky if at least One
Factor is large
4Risk Identification
- Risk Tolerance is a Function of Experience
- PM
- Stakeholders
- Risk of Failure
- Schedule
- Budget
- Technical Goals
- Risk of Opportunity
- Rewards
- Savings
- Benefits
5Risk Identification (Continued)
- Ways to Identify Project Risk
- Chronology
- Type of Work
- High Risks
- Approach is New/Unusual
- Technology is New/Unusual
- Staff needs Training in New Tasks/Skills
- Process using New Equipment, Systems or Procedures
6Sources of Risk
- Any Factor of uncertain Probability which can
affect the Outcome is of a Project is a - Risk Source
- Risk Hazard
7Sources of Risk (Continued)
- Internal Risks
- Market Risk
- Ill Defined Market or Customer needs and
Requirements - Failure to Identify Changing Needs and
Requirements - Failure to identify Newly Introduced Products by
Competitors - Technical Risk
- Maturity
- Complexity
- Quality
- Concurrency, or Dependency
8Sources of Risk (Continued)

10Identification Techniques
- Analogy
- Records, History and Lesson Learned from Previous
Projects - Checklist

Risk
11Identification Techniques (Continued)

(Effect)
12Cause and Effect Diagram
13Risk Assessment
- Risk Likelihood
- Probability a Hazard or Risk Factor will
Materialize - Numerical Value between 1.0 (Certain) and 0
(Impossible) - Qualitative Rating
- High Greater than 50
- Medium 20 to 50
- Low 20 or Less
- Composite Likelihood Factor (CLF)
- Sum of Multiple, Independent Risk Sources
14Sources of Failure and Likelihood

16Risk Assessment(Continued)
- Risk Impact
- What Happens if a Risk Hazard Materialized
- Specified in Terms of
- Time
- Cost
- Performance Measures
- Qualitative
- High
- Medium
- Low
17Risk Assessment(Continued)
- Risk Impact (Continued)
- Numerical Measure Between 0 and 1.0
- 0 not Serious
- 1.0 Catastrophic
- Composite Impact Factor (CIF) is the Impact from
Multiple Risk Source, Simple Weighted Average - CIF (W1)TI (W2)CI (W3)SI
18Impact Values for Technical, Cost, and Time
19Risk Assessment(Continued)
- Risk Consequence
- Function or Likelihood and Impact
- Can be Expressed as Numerical rating between 0
and 1.0 - Risk Consequence Rating (RCR)
- RCR CLF CIF - CLF(CIF)
- Can be Expressed as an Expected Value or the
Average Outcome for large Tries - Risk Consequence (Impact) x (Likelihood)
20Risk Assessment(Continued)
- PERT
- Incorporates Risk through the three Estimates for
Each Project Activity - a, Optimistic
- m, Most Likely
- b, Pessimistic
- Use a larger value of b to account for Greater
Risk - This Produces a larger Variance for Project
Completion Time (Add buffer Time to Project) - PERT Provides a Way for Measuring the
Consequences of Risk on Project Completion Times
21Risk Assessment(Continued)
- Risk Priority
- PM must Define a Risk Tolerance Level
- Consider Risks at that Level and Higher
- Team Members Review all these Tasks and Make
Recommendations - In Complex Systems Joint Failures Can Occur
- Bhopal India 10,000 Deaths
- Chernobyl 50,000 Cancer Deaths Forecast
22Risk Response Planning How to Deal with the
Problem
- Transfer the Risk
- Avoid Risk
- Reduce Risk
- Contingency Planning
- Accept Risk (Do Nothing)
23Risk Likelihood, Risk Impact, and Expected Value
Consequences
24Transfer the Risk
- Transfer Partly or Fully from Customer to
Contractor or Vice Versa - Use Contract Incentives
- Fixed Price Contractor Assumes All the RISK for
Cost Over-Run - FP Incentive Fee Contractor 60, Customer 40
- Cost Plus Incentive Fee Contractor 40, Customer
60 - CPFF Customer Assumes almost All the Risk
25Avoid Risk
- Alter the Initial Project Concept
- Eliminate Risky Activities
- Minimize System Complexity
- Reduce End-Item Quality Requirements
- Change Contractors
- Incorporate Redundancies
- Change Safety Procedures
- Better to Reduce Risk to Acceptable Level Than
Eliminate Payoff Opportunity
26Reduce RiskTechnical Performance

- Perform Analysis of Key Technical Parameters
- Models and Simulations
- Use CASE Tools
- Parallel Development on High-Risk Tasks
- Incentivize the Technical Team
- Consultants for Critical Reviews and Assessments
- TE
27Reduce RiskTechnical Performance (Continued)
- Reduce System Complexity to a Minimum
- Reorganize Tasks
- End Item Design
- Decouple Activities
- Contains Failure to one Activity
- Use Design Margins
- A Management Reserve
- Design Value is Greater than Design Requirement
28Reduce RiskMeeting Schedules
- Create Master Project Schedule

Recover - Focus on Critical and Near-Critical Activities

- Establish Communication Channels
- Document Everything of any Value for Lesson
Learned
37Expect the Unexpected
- Do All You Can
- Cannot Cover Every Contingency
- Bonapartes Principle came along before Murphys
Laws, i.e., Something Surely Will Go Wrong Plan
for It to Occur
38Caveats (Bewares)
- Input to RA is Subjective
- Not what will but what might
- Analysis and Planning gives Sense of Power
- Managing not Eliminating
- Stifles Imagination
- Brute Force Approach to Technology
- Micromanagement is Never Appropriate
39Risk Analysis Methods
- Expected Value
- Decision Trees
- Uncertainty and Payoff Tables
- Simulations
40Expected Value
- For A Project,Expected Value Represents the
Average Outcome - Weighted Average of all Outcomes
- Likelihoods are the Weights
- EV SUM (Outcomes x Likelihood)
- Risk Project Time and Cost are Determined Using
Expected Value
41Expected Value (Continued)
- Risk Consequence on Project Duration is Risk
Time, RT - RT (Corrective Time) x (Likelihood)
- Risk Consequence on Project Cost is Risk Cost, RC
- RC (Corrective Cost) x (Likelihood)
- BTE Baseline Time Estimate
- BCE Baseline Cost Estimate
42Expected Value (Continued)
- To Account for Risk factors that Affect the
Project as a Whole - Expected Project Completion Time, ET
- ET BTE RT
- Expected Project Completion Cost , EC
- EC BTC RC
- When ET and EC cannot be Estimated
- ET BTE (1 Likelihood)
- EC BTEC (1 Likelihood)
43Expected Value (Continued)
- A Better Way to Calculate Expected Values for the
Entire Project - Consider each WBS Element/Work Package Separately
- Estimate Risk Likelihood and ET and EC
- Aggregate for the Entire Project
44Expected Value (Continued)
- EC BCE ( (Corrective Cost) x (Likelihood))
45Expected Value (Continued)
- ET BTE ( (Corrective Time) x (Likelihood))
46Project Network With Risk Times from Previous
Table
47Decision Trees
- Decision Tree a Pictorial Representation of
different Chance events or Strategies - Assess the Risk Response which obtains the
best-to-be Expected Consequence - Application
- Cost of Potential Project Failure Against Benefit
of Project Success - Expected Outcome BCE x (Failure Likelihood)
Net Profit x (Probability of Success) - Alternative Risk Responses
- BCE 10M,
- Risk Factor (Likelihood ) 0.6
- Risk Impact 5M
48Decision Tree for Alternative Risk Responses
49Uncertainty and Payoff Tables
- Uncertainty When no Prior Experience Exists EV
Risk Consequence Cannot be Computed - Best Strategy under Uncertainty
- Identify Alternative Routes
- Routes are Called States of Nature
- Consider all Strategies and Assign the Likely
Outcome for Each State of Nature - The Likely Outcomes are Represented in a Payoff
Table
50Payoff Table for Three Strategies and Three
States of Nature
51Uncertainty and Payoff (Continued)
- Regret Any Choice of Strategy other than the
Best One - Minmax Regret A Strategy which minimizes the
regret of not having made the best(max) choice - Regret for a Given State of Nature is the
difference in the outcomes between the Best
Strategy and any other Strategy (Regret Table)
52Regret Table for Three Strategies and Three
States of Nature
53Uncertainty and Payoff (Continued)
- Another Approach to Strategy Selection
- Assume Every State of Nature has the Same
Likelihood using the Maximum Expected Payoff
Criteria - Outcome is Calculated from the Expected Payoff
for Each Strategy as the Sum from Each State of
Nature Value Times the Constant Likelihood Value - The Maximum Value (by Strategy) is the Best
- NB Three of the Four Selection Criteria Yield C
- Irresistible
