In the CAPA lifecycle, which statement best describes the documentation requirement?

• A. Only the initial problem identification must be documented.
• B. Documentation is required only for regulatory audits.
• C. All steps, including problem identification, investigation, actions taken, verification of effectiveness, prevention of recurrence, and documentation, must be recorded.
• D. Documentation is only necessary if corrective action was taken.

Answer: (C)

Documentation in the CAPA cycle must capture the entire sequence from problem identification through prevention, with verification at the end. This means recording how the problem was identified, the investigation to determine the root cause, the actions taken to correct or prevent recurrence, the verification showing those actions were effective, and the overall documentation that ties everything together. Having a complete record ensures traceability, accountability, and demonstrable evidence for audits, training, and continual improvement.

Focusing only on the initial problem misses critical analysis and follow-up steps, so there’s no record of root cause or whether actions actually fixed the issue. Documenting solely for regulatory audits ignores the day-to-day need to verify effectiveness and close the loop. Documenting only when corrective action is taken skips preventive actions and verification, leaving recurrence risks unaddressed. In CAPA, the strength lies in a full, auditable trail of the entire lifecycle.
