Which KPI would measure the timeliness of closing corrective actions?

• A. Deviation rate
• B. CAPA closure rate
• C. Training completion rate
• D. Audit findings

Answer: (B)

Timeliness of closing corrective actions is shown by tracking how quickly actions from corrective and preventive actions are completed and closed within the planned due dates. The CAPA closure rate focuses on this by measuring the completion of corrective and preventive actions against their due dates. In practice, when a deviation or root cause is identified, a CAPA is opened with specific actions and due dates; the closure rate looks at the proportion of those CAPAs that are closed on time. A common calculation is the number of CAPAs closed by their due date divided by the total number of CAPAs opened in the period, expressed as a percentage. A higher rate indicates efficient resolution of issues, while a lower rate points to delays that could leave risks unaddressed. That makes it the best choice for measuring how timely corrective actions are closed. Other metrics relate to different aspects: deviation rate counts how often deviations occur, not how quickly actions are completed; training completion rate focuses on whether training tasks are finished; audit findings quantify problems found, not the speed of closing them.
