質問 # 344
Which of the following statements about risks is most accurate?
- A. Project risks rarely affect product risk.
- B. Product risks rarely affect project risk.
- C. A risk-based approach is more likely to be used to mitigate project rather than product risks.
- D. A risk-based approach is more likely to be used to mitigate product rather than project risks.
正解：D
解説：
In general, project risk and product risk can be hard to differentiate. Anything that impacts on the quality of the delivered system is likely to lead to delays or increased costs as the problem is tackled. Anything causing delays to the project is likely to threaten the delivered system'squality.
The risk-based approach is an approach to managing product risk through testing, so it impacts most directly on product risk.

Which one of the following roles is typically used in a review?
- A. Project sponsor.
- B. Champion.
- C. Custodian.
- D. Author.
正解：D
解説：
The Author is the only role that is typically used in a review. A Champion might sponsor the review process but is not a defined role within an actual review; a Project Sponsor, if technically competent, might be asked to play a defined role within the review process, but whilst using that role they will not be a Project Sponsor; finally, a Custodian might ensure the results are stored safely but would not be involved in the actual review itself.
