A reference diagram for the operational cycle of generating, collecting, validating, and retaining audit evidence — the mechanism behind "audit-ready," not just a compliance checklist.
Evidence that is only collected right before an audit is evidence you cannot trust — treat generation, collection, validation, and retention as a running lifecycle, not a pre-audit scramble.

What this shows
The four-stage operational loop (Generate → Collect → Validate → Retain) that produces defensible audit evidence on an ongoing basis, rather than evidence assembled reactively when an audit is announced.
Intended audience
Compliance leads, IT operations managers, and auditors evaluating whether an evidence program is operational or improvised.
Methodology
Reflects standard audit-evidence-management practice (the generate/collect/validate/retain cycle underlying frameworks such as SOC 2, HIPAA, and NIST-aligned audits) rather than any single named framework’s specific control list.
Limitations
A structural model of the evidence lifecycle, not a control checklist for any specific framework (SOC 2, HIPAA, NIST 800-171, etc.) — those each specify their own required evidence types beyond what this diagram covers.
