Pharmaceutical manufacturing equipment is often connected to sensors, control systems, alarms, interlocks, and electronic records. Verifying that a machine starts correctly is only the beginning. Teams also need evidence that its relevant functions meet defined requirements and support its intended GMP use.
A useful way to approach this is to connect requirements, risk assessment, testing, and documentation from the start.
- Define Requirements Before Testing
Begin with a User Requirements Specification (URS). It should describe what the equipment must do, including relevant process needs, operating ranges, utilities, cleaning requirements, and data requirements.
Requirements should be specific enough to support meaningful verification. If a requirement cannot be linked to a test or other documented verification activity, the team should review whether the requirement or its verification approach needs clarification.
- Use Risk to Set the Scope
Not every function has the same impact on product quality or patient safety. A risk assessment helps identify critical functions and parameters, then justifies the scope and depth of qualification.
This avoids two common problems: unnecessary testing of low-risk functions and insufficient testing of critical ones.
- Organise DQ, IQ, OQ and PQ
DQ: Review the proposed design against user requirements.
IQ: Verify installation, components, utility connections, documentation, and calibration status as applicable.
OQ: Challenge operating functions, alarms, interlocks, and defined parameter ranges.
PQ: Demonstrate consistent performance under representative routine conditions.
Acceptance criteria should be approved before execution. Results must be recorded, and failures or unexpected outcomes should be handled through approved deviation procedures.
- Make Traceability Part of the Workflow
A traceability matrix can link each requirement to its verification activity, result, and associated deviation. The final report should summarise the evidence and state the conclusion on suitability for intended use.
For automated equipment, teams should also assess whether software functions, electronic records, alarms, and access controls fall within the scope of computerised system validation.
- Plan for Changes
Equipment qualification does not replace maintenance, calibration, or change control. Modifications, software updates, and major repairs should be assessed for their potential impact on the qualified state.

The strongest workflow is one in which requirements, risks, tests, and conclusions remain connected throughout the equipment lifecycle.
