(T1430-02-14) Risk-Based Computer System Validation in Pharmaceutical Quality Systems: Practical Outcomes from an Analytical Laboratory Implementation

Purpose: To demonstrate a risk-based approach for Computer System Validation (CSV) tailored to analytical laboratory systems in pharmaceutical quality environments, ensuring compliance with 21 CFR Part 11, GAMP 5, and regulatory data integrity expectations.

Methods: A scalable CSV strategy was implemented to validate a chromatography data system (Chromeleon 7.3) within a GMP-compliant quality control laboratory. The validation lifecycle included risk assessment, user requirements specification (URS), and IQ/OQ/PQ execution. Key deliverables such as traceability matrices, audit trail verification, and data integrity controls were developed. Validation depth was guided by system criticality. Collaboration was fostered between IT, QA, and laboratory stakeholders to streamline execution and documentation.

Results: The validation was completed within six weeks, reducing review cycle time by 30% compared to prior efforts. Traceability and audit trail accuracy improved, and the system passed internal audits with no critical findings. Feedback from cross-functional teams showed improved process clarity, ownership, and readiness for regulatory inspection. Key risks (e.g., audit trail configuration, access control gaps) were identified early and mitigated before system go-live.

Conclusion: Risk-based CSV enables efficient validation of analytical systems while ensuring compliance and data integrity. This case study highlights a practical, scalable roadmap that other pharmaceutical laboratories can adopt to reduce validation burdens and improve audit outcomes.
