This Knowledge Base section describes a risk-based lifecycle approach for validation, ongoing oversight, and requalification of GMP-relevant systems and equipment. The approach integrates risk-based validation strategy, structured risk assessment, and periodic performance evaluation to identify failure risks, assess system stability, and verify continued control. Outputs from risk assessment and periodic assessment are used to define requalification scope and interval based on risk, performance history, and objective evidence, rather than fixed schedules.
