Evidence fails for predictable reasons
Many validation tests are executed correctly, but evidence is weak. Weak evidence creates audit risk because reviewers cannot reconstruct what happened.

Vague results. “Pass” with no proof of what was verified.
Missing context. No roles, no test data, no environment details.
Scattered attachments. Screenshots and logs stored inconsistently.
No traceability. Requirement links missing or unclear.
No review proof. Tests executed but not reviewed and approved per SOP.
How to fix fast
Standardize a test template, require evidence links, and maintain an evidence index. Evidence quality improves immediately when structure is consistent.
How this looks with an agentic layer
The fundamentals above do not change when validation is automated - they get enforced earlier. On a layer like Qualitum, intended use, risk and evidence are structured inputs rather than documents someone remembers to write: agents draft against them, maintain the traceability, and hand the result to a named human for approval.
- Intended use and critical data are captured once and reused across the lifecycle
- Evidence is generated with its traceability attached, not reconstructed for the audit
- The approval - and the accountability - stays with your named reviewer

Editor’s note
Evaluating an agentic platform? Put it on the same grid as the incumbents - and make it produce one real executed protocol.
