An authorized reviewer needs to examine how a workflow was performed, which sources were used, and who approved the result.
Trials, diagnostics, and clinical programs all require evidence that connects an output to its source records, applied rules, transformations, and review events.
Consider a regulatory submission for a blood-based cancer screening test. Reviewers may need to examine clinical results alongside analytical validation, including specimen handling, assay performance, variant-calling methods, and the statistical framework linking ctDNA signal to cancer detection. Keeping that context connected to the original execution can reduce the reconstruction required when questions arise.
Evidence is what allows an authorized reviewer to inspect how a workflow was performed and where accountable decisions occurred.
