Question

A recent change request was implemented with approval; however, it had an unforeseen negative impact on the critical path. Which of the following measures should be taken to ensure the project is not delayed?

Options

AEvaluate the impact of the change.
BExecute the regression plan.
CIdentify and document the root cause of the issue.
DValidate the change was quality checked.

Explanation

When an approved change has an unforeseen negative impact on the critical path, the immediate priority is to execute the regression plan - a pre-defined rollback procedure designed to restore the system or process to its previous stable state. This directly addresses the risk of project delay. Evaluating the impact (A) and identifying the root cause (C) are valid activities but are retrospective; they don't reverse the damage. Validating the quality check (D) is a pre-implementation step that has already been missed. Executing the regression plan is the fastest corrective action to protect the project schedule.
