Explanation:
A corrective action is anything that is done to bring expected future schedule performance in line with the schedule baseline. Regarding the project schedule, it usually means taking action to speed up the project. One way to determine why the schedule
performance is not in line with the plan is what-if analysis, which may address schedule activities and other scenarios other than the activity that is actually causing the variance. It evaluates scenarios in order to predict their effect on the project’s outcomes, either
positive or negative.
