What does the Implementation and Migration Planning phase encompass?

The Implementation and Migration Planning phase in the TOGAF framework focuses primarily on outlining how to transition from the current architecture to the desired target architecture. This phase involves developing a comprehensive plan that addresses the steps, resources, and timeline necessary to achieve the migration effectively. It ensures that the organization has a clear strategy for managing the shift towards the new architecture while aligning with overall business goals.

This phase is critical because it not only encapsulates the technical aspects of moving to a new architecture but also considers factors such as stakeholders' interests, project management aspects, and potential risks involved during the transition. Having a solid implementation and migration plan helps ensure that the transition is smooth and that the organization can adapt to the changes with minimal disruption.

The other choices, while important aspects of enterprise architecture, are not the primary focus of this specific phase. Establishing an architectural governance framework is essential but typically occurs earlier in the process to provide oversight and structure. Evaluating technology options is important for forming the architecture itself but is more aligned with the earlier phases of architecture development. Documenting financial implications relates more to the overall project management and governance, rather than the specific implementation and migration planning aspect.
