Lock programme gate definitions (which gates, in what order, with what criteria)pmo.dec.gate_definitions_lock
P0
GCC
Summary
Lock the canonical set of programme gates that govern phase progression. After lock, adding/removing gates requires Steerco; changing exit criteria for a gate requires the gate's own approval chain.
Rationale prompt skeleton
Rationale should reference the gate definitions question, the evidence-standards question, and the gate approval-chain question. Note any wave structure and how gates compose with milestone progression.
Default options (3)
standard_six_gate_model
Standard 6-gate model (Discovery exit / Design exit / Build entry / Cutover ready / Go-live / Stabilisation exit)
Canonical transformation-programme gate set. Covers the major phase transitions of a 12-24 month build.
Pros
Cons
compressed_three_gate_model
Compressed 3-gate model (Design exit / Cutover ready / Go-live)
Lean gate set for shorter or lower-risk programmes.
Pros
Cons
wave_indexed_gate_model
Wave-indexed gate model (gates duplicated per transition wave)
For multi-wave cutovers (e.g., country-by-country rollout), gates are run per wave rather than once per phase.
Pros
Cons
Default approval chain

Linked evidence questions (4)
| id | prompt | workstream |
|---|---|---|
| pmo.q.gate_definitions | Which phase gates govern this transformation? For each, capture name, position in timeline, exit criteria, and approval chain. | pmo.gate_management |
| pmo.q.gate_evidence_standards | What standard of evidence is required to pass each gate? Define what 'evidence sufficient to approve' looks like (e.g., 'all P0 questions answered AND classified Reviewed'). | pmo.gate_management |
| pmo.q.gate_approval_chain | Who must approve each gate, and in what order? Capture the named approval chain per gate type. | pmo.gate_management |
| pmo.q.conditional_gate_policy | What is the policy on conditional gate approvals (Go with caveats)? When are they permissible, what evidence must be tracked, and what triggers a follow-up gate review? | pmo.gate_management |
