Corrective action evidence is the documented proof used to show that a corrective action was planned, implemented, and, when required, checked for effectiveness. In manufacturing and quality systems, it commonly refers to records that support a response to a nonconformance, audit finding, customer issue, or process failure.
This evidence may include updated work instructions, training records, inspection results, containment records, disposition notes, system change logs, photos, completed checksheets, or follow-up process data. The specific evidence depends on the issue, the action taken, and the organization’s quality process.
Corrective action evidence is not the corrective action itself and is not the same as root cause analysis. Root cause analysis explains why the issue occurred. The corrective action describes what was changed to prevent recurrence. The evidence supports that the change was actually made and can be reviewed in a quality, CAPA, RCCA, 8D, or audit-readiness workflow.
