CDC Waiver Policy: Review Checklist

Review checklist

Review Checklist for CDC Waiver Policy focuses on open critical waivers, stale waiver age, waiver quality score. The goal is to convert issue observations into mechanism-backed closure decisions.

• Crossing and reset intent are explicitly classified.

• Protocol assumptions are documented and checked.

• Critical issues have owners and dates.

• Waivers include mechanism, containment, and expiry.

• Regression matrix includes stress and milestone modes.

• Owners signed: methodology owner, CDC lead, signoff manager.

Signoff ownership

OWNERSHIP MAP — CDC Waiver Policy

artifact                  owner
----------------------    -------------------------
design intent           methodology owner
verification evidence   CDC lead
signoff decision        signoff manager

Every open CDC/RDC issue needs one accountable owner before waiver or fix.

Signoff is an evidence governance problem across teams.

Reports and artifacts

• critical by owner

• waiver quality

• review gate status

• closure trend

Mini case study

Pass rates improved while critical waivers aged out of policy; dashboard exposed hidden risk.

Debug branches

• Separate quality from quantity metrics

• enforce waiver expiry

• run gate checklists consistently

Senior review question

Ask: what evidence proves this risk is closed for silicon, not just tool-clean?

Key takeaways

• State crossing class, assumptions, and owner with every issue.

• Run structural and dynamic regressions after each fix.

Common pitfalls

• Treating all warnings as equivalent risk.

• Waiving issues without containment evidence.

• Skipping reset and reconvergence stress after CDC fixes.

Principal CDC/RDC review addendum

Waivers are controlled risk acceptances and must include mechanism justification, containment evidence, and ownership for periodic revalidation.
