What are the four elements of the ICH Q10 pharmaceutical quality system?

Why

ICH Q10 describes a model quality system that sits on top of regional GMP rules rather than replacing them. Its three objectives are to achieve product realisation, to establish and maintain a state of control, and to facilitate continual improvement. The four elements are how a company does that across the product lifecycle, from development through technology transfer and commercial manufacture to discontinuation.

Monitoring tells you how the process and product are performing, using a control strategy built with risk management. CAPA responds to what monitoring, complaints, deviations, audits and inspections reveal. Change management makes sure improvements and corrections are evaluated before they are made.

Management review closes the loop by having senior leaders look at the results and allocate resources. The elements are linked. A rising trend in impurity results is a monitoring signal, it triggers an investigation and CAPA, the CAPA proposes a process change that goes through change management, and management review checks whether the trend actually reversed.

Knowledge management keeps what was learned available to the next team, and risk management sets how much effort each step deserves. Q10 is guidance, so a regulator inspects against GMP law, but its vocabulary is what most inspectors and auditors use to judge whether a system is more than a set of procedures.
