CAPA — Corrective and Preventive Action — is the quality system's answer to things going wrong. Corrective action responds to a problem that has occurred: contain it, find the root cause, change the process so it can't recur, and verify the change worked. Preventive action does the same reasoning for problems that haven't happened yet but plausibly could.
The discipline is in the follow-through. A CAPA log where every entry ends at 'staff re-educated' is the signature of a system that treats symptoms; root-cause analysis keeps asking why until it reaches something structural — a missing step, an ambiguous form, an impossible workload. Assessors read CAPA records specifically to see whether investigations reach causes and whether effectiveness was ever checked.
Why it matters
Incidents are inevitable; recurrence is optional. A working CAPA process is also the single strongest evidence that your quality system is alive between assessment cycles.

- From Incident to Improvement: Non-conformance, CAPA & Adverse Events under CPSA StandardsCPSA NHSF standards require a system to identify, investigate, and prevent the recurrence of non-conformances and adverse events — including reportable incidents and CAPA. How to build one that actually works.
