What ensures future performance remains aligned with the project management plan?

• A. Corrective action
• B. Defect repair
• C. Preventive action
• D. Change management

Answer: (C)

The focus of ensuring future performance remains aligned with the project management plan lies in preventive action. Preventive actions are proactive measures taken to eliminate the causes of potential deviations from the project management plan before they occur. By identifying risks and implementing strategies to mitigate them, the project team can maintain alignment with the planned project objectives and deliverable timelines.

This approach is essential for keeping the project on track, as it emphasizes foreseeing potential issues and addressing them early. It contrasts with corrective actions, which are reactive and address issues after they have arisen. While corrective actions rectify deviations that have already impacted performance, preventive actions aim to maintain performance standards and prevent issues from occurring in the first place.

Defect repair typically refers to fixing specific flaws in the deliverables, which is more focused on outputs rather than overall alignment with the project management plan. Change management involves handling and integrating changes to the project scope or objectives but does not inherently ensure alignment unless it's coupled with preventive measures. Thus, adopting preventive action is the most effective way to ensure continued alignment with the project management plan.
