What is Performance Qualification (PQ)?

Performance Qualification Definition

The FDA provides guidance applicable to the validation of medical device software or the validation of software that is used to design, develop, or manufacture medical devices. Installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) are the three independent and documented procedures used to validate that software is:

  1. Is installed correctly
  2. Meets its design requirements and specifications
  3. Operates the way in which it was designed under load

After IQ and OQ, the final step of qualifying equipment is PQ. PQ addresses that the software application, under real-life conditions, consistently produces products that, which meet all predetermined requirements. The PQ is the final test before production, testing that the solution works fully in the live environment using live data, and should be based back on a workflow model from your user requirements specification (URS).

FAQs

What is the difference between operational qualification and performance qualification?

What is the purpose of a performance qualification?

PQ testing verifies that end users are able to run their unique processes on the software.
