Definition
An effectiveness check is a planned evaluation performed after a corrective action or CAPA has been implemented to determine whether the action achieved the intended result. It is different from confirming that an action was completed: the check looks for objective evidence that the problem has been controlled, recurrence has been reduced or prevented, and the action has not introduced unacceptable new effects.
Why it matters
For Quality teams, closing a CAPA when tasks are finished is not the same as demonstrating that the CAPA worked. Effectiveness checks create the evidence needed to show that corrective actions changed the underlying condition in practice. Well-designed checks use predefined criteria, an appropriate observation period and relevant data so closure decisions can be defended during audits and management review.
Set measurable or observable criteria linked to the original problem and expected effect of the action.
Define what success should look like
1
Choose timing that gives the changed process enough exposure for meaningful evidence to emerge without delaying closure unnecessarily.
Allow an appropriate observation period
2
Use recurrence data, process performance, audit results, sampling or other relevant information rather than relying only on owner confirmation.
Collect outcome evidence
3
Determine whether the intended outcome was achieved and whether new risks or side effects appeared.
Compare results with the success criteria
4
Close when evidence supports effectiveness; otherwise reopen, revise or escalate the action and continue monitoring.
Decide on closure or further action

Method explained
Checking whether actions solved the problem
An Effectiveness Check evaluates outcomes after a Corrective Action or CAPA has had enough time to work. It should test whether the intended risk or recurrence changed, not merely whether the assigned tasks were completed.
A structured process for addressing causes of actual or potential problems through corrective or preventive measures and verifying that actions are effective.
