Phase F turns the first-cut roadmap from Phase E into a finalised, detailed and costed Implementation & Migration Plan that the business can actually fund and schedule. It's where architecture meets portfolio/project planning.

Phase F — Migration Planning — finalises the Architecture Roadmap and the supporting Implementation and Migration Plan, ensuring it is coordinated with the enterprise's change/portfolio management. It assigns business value and cost to work packages and confirms delivery sequencing.

Key activities: prioritise projects via a cost/benefit and risk assessment, confirm the Transition Architectures, and produce the detailed plan. The Implementation Factor Assessment & Deduction matrix and Consolidated Gaps, Solutions & Dependencies matrix are typical techniques.

Phase F consumes Phase E's first-cut plan and hands a finalised plan to Phase G (Implementation Governance), which oversees the actual build against it.
