The Missing Sign-Off Gate: Catching Absent Approvals at the Source
responsibleai
How AI-powered checks catch missing sign-offs, approvals, and attestations the moment work is submitted — before they become audit findings.
The third compliance gate — anything missing — is the one that shows up in audit findings. A missing signature, an absent attestation, a skipped countersign. Each one is trivial to fix at the source and painful to remediate months later.
What the gate looks for
Beyond field content, work usually requires a chain of approvals: originator sign-off, peer review, supervisor countersign, sometimes external attestation. The AI check verifies the chain is complete — right people, right sequence, right timing.
Why sign-offs get missed
Sign-off rules live in policy documents, not in the workflow tool. People remember the ones they use daily and forget the edge cases. When a rare workflow variant fires — an after-hours submission, a substitute reviewer, a cross-department handoff — the exception rules apply, and that's exactly when the human memory fails.
How the AI verifies the chain
The check receives the artifact, its approval history, and the policy graph — who must sign, in what order, under what conditions. It returns a completeness verdict with any missing steps named. If a substitute is used, the AI verifies delegation authority.
The audit benefit
Every check produces a timestamped record: what was evaluated, against which policy version, with what outcome. That log is the audit trail. When regulators ask how you know sign-offs are complete, you show the log.
Design principles
- Policy versioning. Every check references the policy version in force at submission time.
- Delegation aware. Substitutes and delegations are first-class, not exceptions.
- Fail loud, fail early. Missing sign-offs block downstream movement, not just warn.
