Waiver & Risk Governance: Review Checklist

Review Checklist for Waiver & Risk Governance.

On this page

    Review checklist

    Review Checklist for Waiver & Risk Governance focuses on waiver aging, post-silicon waiver escape rate. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

    • Baseline manifest and revision are explicit.

    • Boundary contracts for this topic are current and approved.

    • Ownership map covers all open issues.

    • Focused and full regression evidence both exist.

    • Residual risks are either closed or bounded via waiver policy.

    • Owners signed: quality lead, signoff lead, executive reviewers.

    No top-level issue should remain ownerless beyond one review cycle.

    Signoff confidence depends on evidence quality and reproducibility discipline.

    Reports and artifacts

    • closure dashboard

    • signoff manifest

    • waiver aging report

    • TRR checklist

    Mini case study

    A near-tapeout risk was caught when manifest mismatch invalidated an apparently green closure report.

    Debug branches

    • Validate manifest integrity

    • Bound waiver risk

    • Audit cross-domain owner approvals

    Senior review question

    Ask: what baseline, owner, and artifact prove this topic is truly closed?

    Key takeaways

    • State baseline manifest and owner with every closure metric.

    • Run cross-domain regression after every top-level fix.

    Common pitfalls

    • Comparing results across different manifests.

    • Unowned issues slipping through review cycles.

    • Waiving risks without expiry and validation plan.

    Principal SoC review addendum

    Waiver governance differentiates acceptable bounded risk from hidden quality debt and enforces traceable owner accountability.
