CSV Evolution: How We Slashed 14,000+ Test Steps Without Missing a Beat

"True CSV excellence isn't measured by the number of pages in your OQ, but by the clarity of your risk-based thinking." 

 

In my previous post, I shared the start of my journey into Computer Systems Validation (CSV) and our initial push toward simplification. Today, I want to dive deeper into how that "simplification mindset" unfolded when put to the test against a massive PLM application.  

 

The "Safety" Trap: When More is Actually Less  

In the early days of our organization’s CSV journey, our natural inclination was to play it safe. We thought "robust" meant "detailed." This led us to create heavy OQ and PQ scripts packed with granular steps and an exhausting number of screenshots.  

The result? A validation nightmare. Project costs skyrocketed due to the sheer volume of man-hours required, and our documentation became a wall of non-value-added tasks. We weren't just validating; we were drowning in data.  

 

The Turning Point: The SME Workshop  

Recognizing that we couldn't scale this way, we gathered our Subject Matter Experts (SMEs) for a simplification workshop. We scrutinized every single script with one question in mind: Does this step actually verify a requirement, or is it just noise?  

The results were staggering:  

  • The Scale: We started with 32,000 individual test steps.  

  • The Reduction: We successfully cut 45% of those steps.  

  • The Outcome: We eliminated nearly 14,000 steps while maintaining 100% compliance with documented requirements and design parameters.  

By focusing on what truly mattered, we didn't just save time—we reduced the surface area for documentation errors.  

 

Beating the Go-Live Clock  

 

As the Go-Live date loomed, we faced another hurdle: execution errors. With the high volume of scripts requiring pre- and post-execution approval, "Review & Fix" cycles were threatening our timeline. Moving the date wasn't an option.  

To tackle this, we implemented a real-time feedback loop:  

  • Proactive Coaching: We shared Good Documentation Practice (GDP) best practices with the testing team before they hit the field.  

  • Continuous Review: Instead of waiting for the end, we provided constant feedback on documentation quality.  

  •  

This shift dropped our error rate from ~5 errors per script to less than 1. We reduced rework by over 25%, saved significant man-hours, and—most importantly—hit our Go-Live date.  

The Takeaway: Compliance Through Simplicity  

Validation success isn't about how thick your binder is; it's about understanding risk and impact. When you keep it practical and simple, you win back time without ever compromising quality.  

To this day, my mantra for mentoring new team members remains: "KEEP IT SIMPLE, SILLY!" (KISS).  

The journey was about to get even more intense, however. Just as we optimized our process, the news broke: An FDA Inspection was announced.  

 

How did our "simple" process hold up under the regulatory microscope? That’s a story for Part III. Stay tuned!
