Stage-Gate Governance

Stage-Gate Governance is the transverse decision-making process by which a product program advances from one lifecycle phase to the next only after a cross-functional gatekeeper body explicitly authorises it. It is the unifying backbone behind Cooper Stage-Gate, Huawei/IBM IPD DCPs (Decision Checkpoints), NASA NPR 7120.5 KDPs (Key Decision Points), and the APQP / AS9145 phase-exit reviews. Without it, every other process in this layer runs without a brake.

Scope

• Gate criteria — entry and exit deliverables for each phase (concept passed, requirements baseline frozen, design verified, V&V complete, production capable, etc.).
• Decisions — go / kill / recycle / hold, with documented rationale; “kill” is a feature, not a failure.
• Gatekeepers — the cross-functional body (engineering, manufacturing, quality, regulatory, finance, marketing) and its delegation rules.
• Scorecards & deliverable checklists — measurable evidence each gate requires; templated per program tier.
• Recycle / bypass paths — what to do when a gate fails; how exceptions are escalated.
• Portfolio-level views — aggregate gate status across all active programs to balance load and budget.

Relationships (see sidebar)

• Realizes Operational Excellence, Innovation Velocity, and Product Quality.
• Supported by Workflow Engine, KPI Dashboard, Product Analytics, and Change Control Board (a gate is an extended-CCB pattern).
• Runs across every other process in this layer: from Portfolio Planning (Gate 1) to End-of-Life (final closure gate).
