Computerized system validation without the paperwork spiral

Validation earned a reputation for being slow because teams treated every system the same way — exhaustive scripts, thick binders, and testing that duplicated the vendor's own work.

GAMP 5 is explicit: scale the effort to risk. Leverage supplier documentation, focus testing on the functions that affect patient safety and product quality, and let critical thinking replace box-ticking. Done well, validation becomes an enabler rather than a bottleneck.
