In which ADM phase is an outline Implementation and Migration Strategy generated?

In the Architecture Development Method (ADM) of TOGAF, an outline Implementation and Migration Strategy is generated during Phase E, which is the Opportunities and Solutions phase. This phase focuses on identifying the various opportunities for implementing the architecture and determining solutions that align with the organization’s goals.

During Phase E, the team evaluates the architectural work completed in the earlier phases and starts to lay out the strategies for moving from the current state to the desired future state. This includes considerations of timelines, resources required, and potential approaches for implementation. The result is an outline strategy that guides the organization in how to effectively migrate to the new architecture, taking into account any dependencies, risks, and necessary changes.

The other phases do not specifically focus on creating this outline strategy. Phase F deals with the Migration Planning, which is more about detailing the operational plan and assessing the impact rather than generating the outline strategy itself. Phase G involves the implementation governance, focusing on ensuring that the implementation adheres to the defined architecture. Phase H is centered around architecture change management, which is primarily concerned with managing changes to the architecture over time. Thus, the creation of an outline Implementation and Migration Strategy is best situated in Phase E.
