QMS

Quality Management System

A quality management system is the deliberate structure through which an organisation directs and controls quality: the policy and objectives, the processes and their interactions, defined responsibilities and authorities, the documentation that governs work, and the mechanisms — audit, review, CAPA, change control — by which the system corrects and improves itself. The generic reference is ISO 9001:2015, built on a process approach, risk-based thinking, and the Plan-Do-Check-Act cycle.

The regulated sectors specialise it. Pharmaceutical manufacturers implement ICH Q10 as the Pharmaceutical Quality System, layered on top of binding GMP. Medical device manufacturers implement ISO 13485:2016, which deliberately diverges from ISO 9001 by prioritising regulatory compliance and risk management over customer-satisfaction language — and in the US, the FDA Quality Management System Regulation incorporates ISO 13485 by reference, taking effect in February 2026.

A certificate is not a quality system. ISO 9001 or 13485 certification demonstrates that a system was assessed against a standard on a given date; it does not demonstrate that the system is used, that management engages with it, or that problems surface honestly. That gap between a documented system and a lived one is exactly what maturity models were created to measure.

• —Policy and objectives, processes, responsibilities, documentation, and self-correction mechanisms.
• —Generic reference ISO 9001:2015 — process approach, risk-based thinking, Plan-Do-Check-Act.
• —Pharma specialises it as the ICH Q10 PQS, on top of binding GMP.
• —Devices use ISO 13485:2016; the FDA QMSR incorporates it by reference from February 2026.
• —ISO 13485 diverges from ISO 9001 by prioritising regulatory and risk requirements.
• —Certification proves assessment, not effectiveness — maturity is the missing dimension.
