Achieving Computer System Validation (CSV) compliance is not the end of the journey—it’s only the beginning. Once a system has been validated and approved for use, it must remain compliant throughout its lifecycle. Regulatory bodies such as the FDA (21 CFR Part 11), EMA, and ICH expect organizations to maintain validated status through post-approval maintenance, including change control and revalidation.
At BioBoston Consulting, we help pharmaceutical, biotech, and medical device companies establish robust post-approval strategies that ensure systems remain reliable, compliant, and inspection-ready.
Why Post-Approval Maintenance Matters
Even after validation, systems evolve due to software upgrades, configuration changes, new business needs, or regulatory updates. Each change poses potential risks to compliance and data integrity.
Without effective post-approval processes, organizations risk:
- Non-compliance with FDA 21 CFR Part 11 and EMA regulations
- Data integrity breaches or audit trail failures
- System downtime and operational inefficiencies
- Costly rework and failed regulatory inspections
A strong maintenance framework ensures ongoing CSV compliance and regulatory confidence.
The Role of Change Control in CSV
Change control is a structured process for managing modifications to validated systems. It ensures that every change is assessed, documented, and approved before implementation.
Key elements of change control include:
- Impact Assessment – evaluating the effect on compliance, data integrity, and patient safety
- Risk-Based Approach – prioritizing critical changes that may affect system performance or regulatory requirements
- Documentation – maintaining records of requested changes, approvals, and test evidence
- Stakeholder Involvement – engaging IT, QA, and end-users in decision-making
By implementing robust change control, organizations maintain system integrity and reduce compliance risks.
Revalidation: Ensuring Ongoing Compliance
Revalidation ensures that systems remain in a validated state after changes, upgrades, or migrations. Depending on the scope of change, revalidation may include partial or full testing.
Triggers for revalidation include:
- Software patches, upgrades, or new releases
- Hardware changes or infrastructure updates
- Process or workflow modifications
- Regulatory requirement updates
- Findings from audits or inspections
Revalidation activities typically include:
- Updating the User Requirements Specification (URS) or design documents
- Executing IQ, OQ, PQ testing for impacted functions
- Revising traceability matrices and validation reports
- Documenting results in compliance with CSV standards
Best Practices for Post-Approval Maintenance
To ensure effective CSV change control and revalidation, organizations should follow these best practices:
- Adopt a risk-based validation approach for efficient resource use
- Establish clear Standard Operating Procedures (SOPs) for change control
- Maintain traceability from requirements through revalidation evidence
- Train staff on regulatory expectations and change control workflows
- Perform periodic system reviews to confirm ongoing compliance
