Working checklist
Use each item as a discussion prompt. Record evidence, owners, assumptions, and unanswered questions rather than treating this as a pass/fail score.
- 1Begin with business consequence and change constraints
- 2Separate urgent stabilisation from structural modernisation
- 3Map boundaries, data ownership, integrations, and hidden dependencies
- 4Compare retain, remediate, expose, replatform, replace, and retire options
- 5Choose seams that permit staged change and rollback
- 6Define observability, data reconciliation, and acceptance criteria
- 7Sequence delivery around operational risk and internal capacity
- 8Keep each phase accountable to a decision or measurable outcome
