Preventive Action

A deliberate step taken to keep upcoming project work in line with the project management plan.

Key Points

  • Proactive measure taken before issues or deviations occur.
  • Targets future performance so work stays aligned with the plan and baselines.
  • Often formalized as a change request and may update procedures or processes.
  • Different from corrective action (fixes existing variance) and defect repair (fixes a product defect).

Example

After identifying a rising risk of rework, the project manager introduces a mandatory design review checklist and early peer code reviews to prevent defects from entering development.

PMP Example Question

Which of the following best illustrates a preventive action?

  1. Revising the schedule to recover from a missed milestone.
  2. Adding automated unit tests before development to avoid future defects.
  3. Fixing a bug discovered during system testing.
  4. Applying a temporary workaround to bypass a supplier delay.

Correct Answer: B — Taking a deliberate step to prevent future deviations and keep work aligned with the plan

Explanation: Preventive actions are proactive activities intended to ensure future work meets the project management plan. Options A and C address existing problems, and D is a temporary workaround.
