PQS

Pharmaceutical Quality System (ICH Q10)

ICH Q10 built the PQS on the ISO 9001 concept but extended it across the whole product lifecycle — pharmaceutical development, technology transfer, commercial manufacturing, and product discontinuation — with the explicit objectives of realising the product, establishing and maintaining a state of control, and facilitating continual improvement.

Four elements carry the operational load: a process performance and product quality monitoring system, a corrective and preventive action system, a change management system, and management review. Two enablers run underneath all four — knowledge management (what the organisation has learned about the product and process, and whether it survives staff turnover) and quality risk management (how effort and scrutiny are prioritised).

The element regulators probe hardest is management responsibility. Q10 expects senior management to define a quality policy, resource the system, and personally participate in management review — not to delegate quality entirely to a quality unit. That is the same terrain FDA’s Quality Management Maturity programme assesses under Management Commitment to Quality, and it is where a technically compliant system and a genuinely effective one visibly diverge.

• —Spans the full lifecycle: development → technology transfer → commercial manufacturing → discontinuation.
• —Three objectives: achieve product realisation, establish and maintain a state of control, facilitate continual improvement.
• —Four elements: process/product monitoring · CAPA · change management · management review.
• —Two enablers: knowledge management and quality risk management.
• —Management responsibility is explicit — senior leaders resource and review the system personally.
• —Complements regional GMP requirements; it does not replace 21 CFR 211 or EU GMP.

ICH Q10 Pharmaceutical Quality System (2008); implemented in the EU as EudraLex Volume 4 Part III and reflected in Part I Chapter 1; recognised by FDA as guidance for industry. Builds on ISO 9001 concepts and works with ICH Q8(R2), Q9(R1), Q11 and Q12.
