CEP Risk Analysis & Value Engineering 3 — Questions and Answers
Question 1: Which technique assigns three time/cost estimates (optimistic, most likely, pessimistic) to model uncertainty in project variables?
- Three-point estimating (PERT) (Correct answer)
- Delphi technique
- Analogous estimating
- Parametric estimating
Correct answer: Three-point estimating (PERT)
Three-point estimating uses optimistic, most likely, and pessimistic values to calculate a weighted average and measure uncertainty.
Question 2: A value engineering study identifies a component with a cost-to-worth ratio of 3.5. This indicates:
- The component costs 3.5 times more than its function is worth (Correct answer)
- The component delivers 3.5 times more value than its cost
- The component's function is unnecessary
- The component's cost is within acceptable limits
Correct answer: The component costs 3.5 times more than its function is worth
A cost-to-worth ratio greater than 1 means the current cost exceeds the worth of the function, signaling a VE opportunity.
Question 3: Which statistical measure best describes the dispersion of possible cost outcomes in a risk analysis?
- Standard deviation (Correct answer)
- Mean
- Mode
- Median
Correct answer: Standard deviation
Standard deviation quantifies the spread or variability of outcomes around the mean, making it the primary measure of dispersion.
Question 4: In a tornado diagram used for sensitivity analysis, the longest bar represents:
- The variable with the greatest impact on cost (Correct answer)
- The variable with the highest probability of occurrence
- The risk with the largest contingency reserve
- The assumption with the lowest confidence level
Correct answer: The variable with the greatest impact on cost
In a tornado diagram, bars are sorted by length so the longest bar at the top represents the most influential variable.
Question 5: Value engineering is most effectively applied during which project phase?
- Conceptual or early design phase (Correct answer)
- Construction phase
- Closeout phase
- Procurement phase
Correct answer: Conceptual or early design phase
VE savings potential is highest during early design when changes are least costly and most impactful.
Question 6: A project risk matrix plots risks on axes of probability and impact primarily to:
- Prioritize risks for response planning (Correct answer)
- Calculate exact contingency reserves
- Replace quantitative risk analysis
- Document risk ownership
Correct answer: Prioritize risks for response planning
The probability-impact matrix visually prioritizes risks so teams focus resources on those with highest combined scores.
Question 7: Which risk response strategy involves shifting the financial impact of a risk to a third party?
- Transfer (Correct answer)
- Mitigate
- Accept
- Avoid
Correct answer: Transfer
Risk transfer moves the financial consequence of a risk to another party, typically through insurance or contracts.
