FDA Computer Software Assurance (CSA) for Manufacturing & Quality Systems

Transitioning from burdensome CSV paperwork to critical thinking, risk-based testing, and automated assurance.

Executive Overview

FDA Computer Software Assurance (CSA) shifts the validation paradigm for non-product automated manufacturing and QMS software from generating reams of low-value paper evidence to high-impact risk analysis, unscripted exploratory testing, and continuous automated CI/CD assurance.

1. CSA vs Traditional CSV Paradigm

Under traditional Computer System Validation (CSV), 80% of effort was spent writing documentation and only 20% on actual testing. CSA flips this ratio:

  • Focus testing strictly on features that directly impact product quality and patient safety.
  • Leverage vendor audits and supplier documentation for standard commercial off-the-shelf (COTS) features.
  • Utilize automated testing, exploratory testing, and unscripted testing with captured error screenshots rather than manual step-by-step paper test scripts.

Frequently Asked Questions

Does CSA eliminate the need for validation documentation?

No; it eliminates redundant, low-value documentation, replacing it with lean, risk-justified evidence proportional to patient safety risk.
