Which is the final step in the 8D problem-solving process?

• A. Define the problem
• B. Containment
• C. Root cause analysis
• D. Prevent recurrence and verification of effectiveness

Answer: (D)

This question tests understanding of how the 8D process is finally closed. After identifying the root cause and implementing a permanent corrective action, the last step is to ensure that the fix truly prevents recurrence and that its effectiveness is verified. This means confirming through follow-up data, tests, or monitoring that the issue does not reappear and that the corrective action works across the affected process or product. It also involves documenting results, updating procedures or control plans, and sharing lessons learned so the improvement is built into the system. Earlier steps focus on describing the problem, containing the issue, and performing root-cause analysis. Those steps set up the solution, but they aren’t the final closure. Recognizing the team is important, but the final closure in the QA sense is proving that the solution sticks and is effective.
