The team treated Category 4 as a pure black-box, assuming all configurable parameters were benign. They lacked a parameter criticality assessment .
Configuration and Risk Management of GAMP Category 4 Software: Moving Beyond Black-Box Validation gamp 4 category
The International Society for Pharmaceutical Engineering (ISPE)’s GAMP (Good Automated Manufacturing Practice) guide provides a risk-based approach to validating computerized systems in the pharmaceutical and biotech industries. Central to this framework is the categorization of software based on its complexity, standardization, and intended use. The team treated Category 4 as a pure
To address these risks, modern Category 4 validation must incorporate: Central to this framework is the categorization of
While GAMP 4 prescribed a rigid V-model, GAMP 5 (Second Edition) recommends a streamlined but rigorous process tailored to configuration risk.
Understanding the distinction between configuration and customization is critical.
They revalidated by implementing a risk-based parameter classification (Critical, Major, Minor) and added automated configuration drift detection.
