A practical model for defining intended use, translating GDP needs into acceptance criteria, qualifying equipment under representative conditions, controlling release to use and preserving the qualified state through maintenance, calibration, change and requalification.
Set intended use, criticality, requirements and failure risks before choosing the qualification depth.
Assess design and supplier evidence, then plan representative and worst-case qualification tests.
Resolve deviations, define the qualified operating state and preserve it through calibration, maintenance and change.
Trend overdue controls, recurring failures, requalification needs, obsolescence and investment decisions.
This model supports GDP premises and equipment controls for human-medicines distribution. Qualification depth should reflect intended use and risk; temperature mapping, calibrated monitoring and requalification should be applied where relevant to the actual storage, handling or transport system.
Source review: 22 September 2026. Confirm current GDP requirements, equipment configuration, product needs and organisation procedures before formal qualification or release-to-use decisions.
