Capa Effectiveness Check: A process which evaluates the effectiveness of Corrective and Preventive Action (CAPA) plans. It is a structured quality management approach designed to identify areas in need of improvement and then implement appropriate corrective action. This practice involves assessing whether the CAPA plan has resulted in sufficient improvement, as well as identifying any potential gaps or further areas for improvement. The end goal is to ensure that corrective actions are able to effectively address key sources of process nonconformances, thus promoting quality assurance and organizational success.
