An effectiveness check is a measurement

Placeholder. This article is placeholder copy written to test layout and tone. It is not published research and makes no factual claims.

Corrective and preventive action (CAPA) closes with an effectiveness check. In many systems that check is a signature confirming the action was completed. This piece describes what a measurable check contains instead.

What to define before closure

A measurable check names the outcome, the observation period and the threshold in advance. It is scheduled when the CAPA is opened, not when it is closed.

Reading the result

If the measure stays within its threshold for the full period, the check passes. If it does not, the CAPA is reopened. Both results are evidence.
