Quality Investigation and Corrective and Preventative Action (CAPA) Support A key component of any modern quality system in the pharmaceutical, biologic, and medical device industries is the risk-based response to observed manufacturing, testing, and distribution discrepancies, or as the result of product complaints. Good Manufacturing Practice (GMP) regulations and industry guidance all describe the criticality of implementing a structured approach to performing investigations with the intent of determining root cause of the discrepant issue. Determining the root cause is necessary to implement specific and effective corrective and preventative action (CAPA) to remediate and prevent reoccurrence of the issue, and consequently facilitate continuous improvement.
