Performance Qualification documents that equipment or a system consistently performs effectively under actual or representative operating conditions.
What PQ demonstrates
PQ may confirm:
- Required capacity
- Product quality
- Repeatability
- Process control
- Operating conditions
- Cleaning or environmental performance
- User operation
- Sustained results
Practical example
A filling line repeatedly produces acceptable output at approved speed using normal operators and materials.
PQ evidence
The protocol should define runs, conditions, samples, acceptance criteria, deviations, and conclusion.
Qualification sequence
IQ confirms installation.
OQ confirms controlled operation.
PQ confirms consistent intended performance.
Common mistake
Using one successful production run as complete PQ may not demonstrate repeatability.
How this term differs
Performance Qualification is documented confirmation of consistent performance in actual or representative use. It is related to Operational Qualification, Installation Qualification, and Commissioning, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
