Performance Qualification Protocol for Distributed Control System in Production
Document Control:
Document Number: PQ-DCS-001
Version: 1.0
Effective Date: [Insert Date]
Review Date: [Insert Date]
Objective
The objective of this Performance Qualification (PQ) protocol is to ensure that the Distributed Control System (DCS) operates according to specified requirements and meets the acceptance criteria outlined in the User Requirements Specification (URS) and 21CFR11.
Scope
This protocol applies to the validation of the DCS used in the production area for process control. It encompasses all critical functionalities impacting product quality.
Responsibilities
The following roles are responsible for the execution and oversight of this PQ protocol:
- Validation Team: Execute test cases and document results.
- Quality Assurance: Review and approve the protocol and results.
- IT Department: Ensure system integrity and support during testing.
Prerequisites
Prior to executing this protocol, the following prerequisites must be met:
- Completion of Installation Qualification (IQ) and Operational Qualification (OQ).
- Training of personnel on DCS functionalities.
- Availability of necessary documentation, including URS and system specifications.
Equipment Description
The Distributed Control System (DCS) is a software-based system used for process control in manufacturing. It includes functionalities such as real-time monitoring, control of production processes, and data logging.
Test Plan
| Test ID | Procedure | Acceptance | Evidence |
|---|---|---|---|
| PQ-DCS-01 | Verify audit trail functionality | Audit trail logs all changes with timestamps | Audit trail report |
| PQ-DCS-02 | Test alarm system integrity | Alarms trigger correctly under defined conditions | Alarm test logs |
| PQ-DCS-03 | Check access control features | Access is restricted based on user roles | Access control report |
Detailed Test Cases
Test Case: PQ-DCS-01
Objective: Verify that the audit trail captures all relevant data changes.
Procedure: Make changes to system settings and verify that each change is logged with the correct timestamp and user ID.
Expected Result: All changes are logged accurately.
Test Case: PQ-DCS-02
Objective: Ensure the alarm system functions correctly.
Procedure: Simulate conditions that should trigger alarms and verify that alarms are activated.
Expected Result: Alarms are triggered as expected.
Test Case: PQ-DCS-03
Objective: Validate access control measures.
Procedure: Attempt to access the system with different user roles and verify access restrictions.
Expected Result: Access is granted or denied according to user roles.
Deviations
Any deviations from the acceptance criteria must be documented and assessed for impact on system functionality and compliance.
