5. Phases A–F (typical mapping)
| Blueprint phase | Typical phased locus |
|---|---|
| A Shape | Initiate; charter; high-level requirements |
| B Plan | Planning; WBS; schedule baseline |
| C Build | Design and implementation per baseline |
| D Verify | Test phases; inspections; exit evidence |
| E Release | UAT; deployment; handover |
| F Learn | Operate; warranty; benefits realization |
6. Flow details (walkthrough)
Stage sequence — The linear diagram is pedagogical; real programs may overlap stages where policy allows. Gates sit on transitions; each stage produces baselines the next consumes. Map org stage names to blueprint A–F for one language across RAID, audits, and agents.
Gate decision — Gate packs prove exit criteria (quality, risk, readiness). Failed criteria mean hold and corrective actions, not silent waivers. Sponsor or steering approval commits spend and the next baseline; defer, kill, or replan are valid.
Change control — Change requests and impact analysis (schedule, cost, risk, traceability) feed steering decisions: re-baseline with versioned artifacts, or reject/queue. Ad-hoc scope without this path breaks audit trails.
Traceability — Requirement ID → design → test case → release note supports impact analysis and demonstrates coverage to auditors.
