Overview
Release Evidence and Audit Trail is a risk-scaled specialization of Release Documentation. How rigorously documentation must be retained, attested to, and made auditable scales with the criticality and regulatory exposure of the Asset involved.


Best Practice
Define Evidence and Audit Trail requirements (retention duration, immutability, attestation, accessibility) explicitly per Risk Classification tier, as a standing enterprise policy — not decided ad hoc, Release by Release.
Benefit(s)
- Ensures higher-risk Assets get appropriately rigorous evidence handling automatically, without over-burdening low-risk Assets with unnecessary compliance overhead.
Antipattern
Applying uniform, one-size-fits-all evidence retention/attestation requirements across every Release regardless of Risk Classification.
