Content focuses on risk-based validation, periodic review, and requalification of GMP systems and equipment. Topics include risk assessment, FMEA, fault tree analysis, system criticality, performance trending, change history, deviation review, and evidence-based requalification decisions. Emphasis is placed on using documented risk and operational data to establish appropriate review intervals, define requalification scope, and maintain systems in a qualified state.
A risk-based validation approach uses documented scientific and technical evaluation to determine the appropriate scope, depth, and rigor of validation activities. It concentrates validation effort on systems, functions, parameters, and controls whose failure could affect product quality, patient safety, data…
Risk Assessment is a structured evaluation of potential failure modes associated with GMP-relevant systems, equipment, utilities, and processes that may impact product quality, patient safety, data integrity, or regulatory compliance. Within a validation lifecycle, risk assessment is used to define…
Fault Tree Analysis (FTA) is a structured risk analysis technique used to evaluate how combinations of failures can lead to a defined undesired event. In regulated pharmaceutical and medical device environments, FTA is typically applied to complex systems, high-risk processes,…
Periodic Equipment Assessment is a structured, documented review performed to confirm that GMP-relevant equipment, systems, and utilities remain fit for their intended use and continue to operate in a state of control following initial qualification. Unlike initial validation, which establishes…
Risk-based requalification is a documented process used to determine whether previously qualified equipment, systems, or utilities require additional qualification testing. It also defines which functions must be tested and when the work should be performed. The decision is based on…
