Insight Brief · CSA & CSV

CSA vs traditional CSV:
how to modernise without increasing inspection risk.

Computer Software Assurance encourages a shift from document-heavy validation to risk-based assurance that focuses on what matters. It does not remove the need for control, traceability or defensible evidence; it changes where effort should be directed.

What CSA Changes

CSA-aligned decisions
inspectors respect.

Inspectors assess whether the assurance rationale is coherent and proportionate, not whether it follows a specific documentation format. These four principles underpin a defensible CSA approach.

01
Intended use and criticality mappingScope decisions flow from intended use and patient or product impact. This is the foundation of a defensible CSA approach and justifies all downstream decisions.
02
Risk-based testingTesting effort is directed at high-risk functions. Scripted testing remains appropriate where risk demands it. CSA does not eliminate it.
03
Appropriate evidenceEvidence is proportionate to risk. The form may change; the requirement for traceability and retrievability does not.
04
Traceable decisionsDecisions must be recorded and defensible under inspection. CSA does not mean undocumented; it means purposefully documented.
Common Misinterpretations

Three things CSA
does not mean.

These misreadings consistently create inspection risk when CSA is applied without sufficient governance rigour.

01
"CSA means less testing"Incorrect. CSA means proportionate testing linked to risk. For high-risk functions, rigorous scripted testing remains the expectation under both FDA and EMA regulatory frameworks.
02
"CSA means no documentation"Incorrect. Decisions must be recorded and repeatable. The format may be lighter; the traceability requirement is unchanged.
03
"CSA is only for agile teams"Incorrect. CSA applies wherever risk-based assurance improves quality and efficiency, regardless of development methodology or system type.
04
"Vendor SOC 2 covers our obligations"Incorrect. SOC 2 addresses security controls. GxP obligations for validation, data integrity and change governance remain with the regulated organisation.
Common Questions

Frequently asked.

Will CSA satisfy EU Annex 11 expectations?
Yes, when applied correctly
When risk-based decisions are documented, traceability is sufficient, and controls for records and signatures are demonstrably effective. The assurance approach must be justifiable, not just lighter.
Do we still need IQ/OQ/PQ?
Sometimes, apply a risk-based approach
The form may change, but evidence that the system is fit for intended use remains essential. For high-risk systems, structured lifecycle phases remain the most defensible approach.
What is the most valuable CSA change?
Shifting effort to control effectiveness
Moving from producing documents to proving control effectiveness and sustaining governance in BAU. Evidence should demonstrate the system is controlled, not just that it was once validated.
