Pillar 04

Quality Assurance & QMS

A quality management system is the organizational framework inside which data integrity, validation, and all other GxP disciplines operate. ICH Q10 describes the pharmaceutical quality system; ICH Q9(R1) provides the risk framework that lets you allocate effort proportionally. Without these foundations, DI and validation programs become disconnected compliance exercises rather than integrated quality functions.
