CBAP Question #148: Real Exam Question with Answer & Explanation
The correct answer is D. Interviewing. The interviewing technique in quantitative risk analysis uses expert judgment and historical data to estimate the probability and impact of risks on project objectives.
Question
Which of the following quantitative risk analysis techniques relies on experience and past data to compute the probability and impact of risks on project objectives?
Options
- AProbability distribution
- BSensitivity analysis
- CModeling and simulation
- DInterviewing
Explanation
The interviewing technique in quantitative risk analysis uses expert judgment and historical data to estimate the probability and impact of risks on project objectives.
Common mistakes.
- A. Probability distribution is a mathematical representation of possible outcomes and their likelihoods, used to model uncertainty statistically rather than through expert experience.
- B. Sensitivity analysis examines how changes in individual risk variables affect overall project outcomes using mathematical models, not experience or historical data directly.
- C. Modeling and simulation - such as Monte Carlo analysis - uses computational algorithms and statistical models to project risk outcomes, not expert experience or past data in the same direct way.
