The Nonconformance, MRB and CAPA Cluster explains how quality issues should flow through execution instead of living in parallel systems. It covers how nonconformances are detected, contained, dispositioned, corrected, and prevented, with clear ownership and timing expectations. The content makes pause, quarantine, rework, and resume mechanics explicit so quality actions are operationally enforceable. This cluster connects quality events directly back to work instructions, traceability, and prevention rather than treating them as paperwork exercises.
