This course provides an introduction to the requirements of systematic failure investigation (FI) and corrective and preventive action (CAPA) practices as described in ICH Q9 and made a regulatory requirement in Europe by Annex 20 of the Guide to GMP, and in the USA by the Federal Register/FDA Guidance for Industry. The course is focused on company responsibilities within a quality risk management system, and several investigational tools are explored to help build up knowledge of techniques that might be used by a company to provide a structure for systematic investigation of failure. Numerous exercises are run throughout the course to provide realistic examples of events requiring investigation, providing an opportunity to practice investigation and writing up of corrective actions within teams. Examples of the use of, and outputs from, more complex techniques are presented.
