HKSM

A deliberate action taken to change a product or component that does not meet requirements so that it becomes compliant.

Key Points

• Addresses deliverables or components that fail to meet specifications or acceptance criteria.
• Typically originates from inspections or testing and is submitted as a change request for approval.
• Can impact scope, schedule, cost, and risk; plans and baselines may need updates.
• Repaired items are re-tested or re-inspected to confirm they now comply.

Example

During quality inspection, several welded joints on a steel frame are found below strength requirements. The team submits a change request, receives approval, re-welds the affected joints, and then re-tests them to verify they meet the specification. This is defect repair.

PMP Example Question

While testing, 12 of 200 circuit boards fail tolerance limits. The project manager submits a change request to replace the faulty resistors on the affected units. What is this action?

1. Corrective action to bring overall project performance back in line
2. Preventive action to reduce the probability of future defects
3. Defect repair to rework nonconforming outputs
4. Workaround to handle an unplanned issue without formal approval

Correct Answer: C — Defect repair to rework nonconforming outputs

Explanation: The action changes defective deliverables to meet requirements, which is defect repair, not corrective or preventive action.
