| 1. Align | Working sessions with the executive sponsor and process owners to establish the mission, the measurable objectives and the constraints that are genuinely fixed. | Objectives and success criteria, stakeholder map, constraint register. | Sponsor agrees the definition of success in writing. |
| 2. Assess | Technical, functional and commercial assessment of the current estate: architecture, integrations, data quality, licensing exposure, operational load. | Current‑state assessment, risk register with owners, effort and duration ranges. | No material unknown remains unnamed. |
| 3. Consult | Options presented with trade‑offs, cost shape and risk — including the option to do less, and the option to defer. | Options paper with a recommendation and its reasoning. | Decision made by the client, not assumed by us. |
| 4. Affirm | Scope, sequence, ownership, assumptions and the definition of done are written down and signed before mobilisation. | Charter, RACI, schedule baseline, change‑control procedure. | Every deliverable has a named owner on both sides. |
| 5. Execute | Delivery against the agreed method, with AIDA ECOS™ performing the repeatable build, migration and environment work and recording evidence as it goes. | Working configuration, migrated data, environment parity, weekly evidence pack. | Evidence — not status colour — shows the build meets design intent. |
| 6. Test | Validation against design intent across unit, string, integration, performance and user acceptance, with defects triaged daily rather than banked. | Test evidence, defect burn‑down, performance results, cutover rehearsal outcomes. | Rollback has been rehearsed, not just documented. |
| 7. Deliver | Cutover to a distinct committed date, hypercare with defined response commitments, then transition to run. | Go‑live, hypercare log, run‑book, knowledge transfer, closure report. | The operating team can run it without us in the room. |
