CAPA stands for corrective and preventive action. A corrective action removes the cause of a problem that has already happened so it does not recur; a preventive action removes the cause of a potential problem before it happens. In GMP manufacturing, CAPA is the system that turns deviations, complaints, audit findings, and trends into investigated, documented, and verified fixes.
Correction, corrective action, and preventive action
| Term | What it does | Example: wrong label on a lot |
|---|---|---|
| Correction | Fixes the immediate problem | Quarantine and relabel the affected lot |
| Corrective action | Removes the root cause so it does not recur | Add a label verification step at line clearance |
| Preventive action | Removes the cause of a problem that has not happened yet | Apply the same check to the other packaging lines |
Where CAPA comes from in the regulations
For drugs, Part 211 requires thorough investigation of discrepancies and failures (211.192) and of complaints (211.198), and ICH Q10 names CAPA as one of the four elements of a pharmaceutical quality system. Part 111 does not use the word CAPA, but it requires quality control review and investigation of deviations, specification failures, and complaints. See the Part 211 and Part 111 guides.
The CAPA process, step by step
- Identify and document the problem specifically
- Assess its risk and how far it reaches
- Contain it with an immediate correction
- Investigate the root cause with evidence
- Define corrective and preventive actions with owners and dates
- Implement them through change control
- Verify effectiveness against criteria set in advance
- Close with documented quality approval
What makes a CAPA defensible
- A root cause supported by evidence, not "human error" by default
- Actions that address the cause, not the symptom
- Effectiveness criteria defined before the work starts
- Links to the deviation, complaint, change control, and training records involved
- Timely closure, with overdue CAPAs escalated
- Approval by a qualified person
The patterns investigators flag most often are the reverse: CAPAs closed without an effectiveness check, recurring problems treated as new ones, and root causes that stop at the operator.
Where software helps
Most teams track CAPAs in their QMS. The slow part is the work between status changes: gathering evidence, chasing owners, and drafting actions. That is what Ovada does in CAPA management, with the quality leader deciding the root cause and signing the record.
Questions
What is the difference between corrective and preventive action?
A corrective action removes the cause of a problem that already happened so it does not recur. A preventive action removes the cause of a potential problem before it occurs.
What is a CAPA effectiveness check?
A planned review, after the actions are in place, that confirms against criteria set in advance that the problem has not recurred and the actions worked.
Do dietary supplement manufacturers need a CAPA system?
Part 111 does not use the term CAPA, but it requires quality control review, investigation, and documented decisions for deviations, specification failures, and complaints. Most supplement manufacturers run a CAPA system to meet those requirements.
