volume_mute

True or False: The average time required for impact analysis and the average time taken to implement a change request measure exactly the same thing and are interchangeable metrics.

Correct Answer

False

Explanation

These are related but distinct metrics. Impact analysis time relates to determining which components are affected by a change. Implementation time is the time needed to actually modify the system and its documentation after the affected components have already been identified. They may correlate but measure different stages of the process.
