Cross-Framework Evidence Mapping

A single evidence artifact can satisfy multiple framework requirements. The risk assessment report that satisfies EU AI Act Article 9 may also satisfy SOC2 CC3.2 and ISO 27001 A.12.6.1 — if the report is structured to address the requirements of all three. Cross-framework evidence mapping identifies where one artifact serves multiple purposes, reducing the total evidence production burden without reducing compliance coverage.

1. Evidence Reuse Map For each evidence artifact, list every obligation it satisfies across all frameworks. A comprehensive risk assessment report might satisfy four obligations across three frameworks. The reuse map eliminates duplicate evidence production and ensures that changes to the artifact are reviewed against all frameworks it serves.
2. Gap-Fill Artifacts Where a reused artifact partially satisfies a framework requirement, create a gap-fill artifact that provides the missing elements. The risk assessment satisfies three of four SOC2 requirements. A supplemental document covering the fourth requirement completes the coverage without duplicating the entire assessment.
3. Audit Bundle Preparation For each framework, prepare an audit bundle — the complete set of evidence artifacts needed for that framework's audit. The bundle draws from the centralized repository, referencing reused artifacts and including gap-fill supplements. Bundle preparation should take hours, not weeks.
