In today’s fast-evolving pharmaceutical and regulated industries, staying ahead demands not only technical expertise but also a willingness to challenge traditional approaches. Recently, Pierre Winnepenninckx, CEO of No Deviation, and David Bartlett, Senior Manager and SME in Automation, sat down to discuss the future of validation practices. Their conversation shed light on the shift from traditional Computer System Validation (CSV) to the more dynamic, risk-based Computer System Assurance (CSA) approach.
Drawing from their insights, this article explores the critical differences between CSV and CSA, and explains why adopting a risk-based, outcome-focused strategy is essential for organizations aiming to maintain a competitive edge.
CSV: The Pitfalls of “Testing for Testing’s Sake”
Traditional CSV often falls into the trap of focusing on testing each component individually to satisfy auditors, rather than validating that the system delivers its intended business outcomes. Compliance becomes a paperwork exercise rather than a demonstration of fitness-for-purpose.
For example, in a system designed to mix two chemicals precisely, CSV would typically validate the flow meters, temperature controllers, and stirrers separately. Yet, it may fail to detect whether the final chemical mixture consistently meets quality specifications — the actual intended outcome.
Thus, even if every component “passes,” the overall process might still be flawed, exposing critical risks.
CSA: Shifting to a Risk-Based, Outcome-Focused Approach
Computer System Assurance (CSA) corrects this misalignment by focusing validation activities on what truly matters: ensuring that critical process outcomes are reliably achieved.
Key differences include:
- Risk-Based Focus: Instead of exhaustive testing, CSA prioritizes critical functions impacting product quality and patient safety.
- Outcome Validation: Testing is designed around demonstrating that the system achieves its intended use, rather than just proving individual components work in isolation.
- Smarter Testing Strategies: Early, integrated testing and informal design reviews ensure continuous validation throughout development.
In CSA, achieving consistent outcomes inherently proves that the system’s underlying components are performing correctly, reducing unnecessary testing burdens.
Accelerating Delivery with CSA
One of the most compelling benefits of CSA is the potential for faster project delivery:
- Early Cross-Functional Involvement: Automation, process, operations, and quality teams collaborate from the outset, ensuring the system design meets actual process needs.
- Continuous Informal Design Reviews: Testing is embedded throughout development, catching issues earlier and reducing costly rework at the end.
- Agile, Modular Workstreams: Breaking down projects into smaller, testable units allows for rapid iteration and quicker feedback cycles.
- Flexible Change Management: Modular validation enables faster and more controlled handling of late-stage changes, minimizing impacts on the overall project.
This integrated, agile-inspired approach mirrors best practices seen in modern software engineering, adapted to the rigor of regulated environments.
Real-World Impact: Safety, Quality, Delivery, and Cost
Adopting a CSA methodology drives measurable improvements across key project KPIs:
- Safety: Built-in early through EHS (Environment, Health & Safety) integration.
- Quality: Improved by design — systems are fit-for-purpose, not just audit-ready.
- Delivery: Accelerated timelines thanks to continuous validation and reduced rework.
- Cost: Lower project costs by focusing resources on value-added activities and minimizing redundant documentation.
Conclusion: Why It’s Time to Transition
Shifting from CSV to CSA isn’t just a regulatory suggestion — it’s a strategic move. Organizations that embrace CSA principles are better positioned to deliver faster, with higher quality, at lower cost.
At No deviation, we have successfully led CSA-based automation and validation projects for major pharmaceutical clients, helping them achieve faster go-lives and higher compliance confidence.
