Performance Qualification

Performance Qualification (PQ) is a vital stage in the validation process, particularly in regulated industries such as pharmaceuticals, biotechnology, medical devices, and others. The primary purpose of PQ is to demonstrate that the equipment or system consistently performs as expected and meets predefined acceptance criteria when used in its intended operational environment.

Scope of Performance Qualification (PQ):

  • Functional Testing: Evaluate the equipment's performance under actual operating conditions.
  • Accuracy and Precision: Ensure that the equipment produces accurate and precise results within established specifications.
  • Reproducibility: Verify that the equipment consistently provides reproducible results over time and with different users or operators.
  • Worst-Case Scenarios: Test the equipment under worst-case scenarios and conditions to ensure it can handle deviations and variations.
  • Limitations and Boundaries: Define the equipment's operational limits and determine its performance at the extremes of these limits.
  • User Training: Confirm that operators have received the necessary training and can use the equipment effectively.
  • Documentation Compliance: Ensure that all documentation, including standard operating procedures, is accurate and up to date.

PQ Protocol Content:

The PQ protocol is a formal document that outlines the procedures to be followed during the Performance Qualification process. Here's how to write a PQ protocol:

  1. Title and Approval: Begin with a clear and descriptive title for the protocol and include spaces for approval signatures from relevant personnel.
  2. Scope: Define the scope of the PQ, specifying the equipment or systems to be qualified and the boundaries of the study.
  3. Purpose: State the purpose of the PQ, which is to demonstrate that the equipment consistently performs as expected under actual operating conditions.
  4. Responsibilities: List the roles and responsibilities of individuals involved in the PQ, such as the project manager, operators, and quality assurance personnel.
  5. Equipment Details: Provide detailed information about the equipment, including model numbers, serial numbers, and any relevant drawings or schematics.
  6. Functional Testing: Specify the procedures and acceptance criteria for functional testing, including all test scenarios, conditions, and parameters.
  7. Accuracy and Precision: Define the acceptable range of accuracy and precision for the equipment, and document the results of testing against these criteria.
  8. Reproducibility: Detail the methods for assessing reproducibility, including multiple trials or tests by different operators, and confirm the results.
  9. Worst-Case Scenarios: Describe worst-case scenarios and conditions for the equipment and confirm its performance in these scenarios.
  10. Limitations and Boundaries: Document the equipment's operational limits and confirm its performance at the extremes of these limits.
  11. User Training Verification: Confirm that personnel operating the equipment have received the necessary training and are competent in its use.
  12. Documentation Compliance: Verify that all relevant documentation is accurate, up to date, and corresponds with the equipment's operation.
  13. Conclusion: Summarize the results of the PQ, indicating whether the equipment has consistently met the acceptance criteria or if any corrective actions are required.
  14. Appendices: Include any relevant forms, checklists, or supporting documents.
  15. Signatures: Provide spaces for approval signatures from responsible parties, indicating that the PQ was conducted and reviewed as specified.
