What is the purpose of verification in a corrective action plan?

• A. Verification is optional.
• B. Verification demonstrates issue resolution via re-analysis or monitoring.
• C. Verification requires new instrument purchase.
• D. Verification is only for calibration.

Answer: (D)

Verification in a corrective action plan is about proving that the actions taken actually fixed the problem and that the process remains under control. It involves re-analyzing the affected samples, retesting the process, or ongoing monitoring to show that the issue has been resolved and that the corrective measures are working over time. This step is not about calibrating equipment or about optional compliance—it’s a necessary check to confirm effectiveness and sustainability of the fix. While calibration verification can be part of laboratory quality activities, the purpose of verification in a CAPA context is to demonstrate that the issue is resolved through data and monitoring, not to mandate a new instrument purchase or to be limited to calibration alone.
