What ensures that a project transitioning into implementation also smoothly transitions into appropriate Architecture Governance?

The Implementation Governance Model is a specific artifact created during the Migration Planning phase (Phase F) of the TOGAF Architecture Development Method (ADM). Its primary purpose is to define the governance structure, processes, roles, and responsibilities for the implementation phase. This model ensures that as the project transitions into implementation, there is a clear framework to provide architectural oversight, manage compliance, and handle any required changes. It directly facilitates a smooth handover from the architecture development team to the implementation and operational teams, embedding the principles of Architecture Governance into the project's execution and subsequent operation.

A. Implementation Strategy: This is a high-level approach describing how the Target Architecture will be delivered, but it lacks the specific governance details for oversight and control.

C. Transition Plan: This is a broader term for the overall plan to move to the new architecture; the Implementation Governance Model is a specific, crucial component within it.

D. Migration Plan: This details the technical sequence and activities for moving from the baseline to the target state, focusing on the "how" of migration, not the governance "oversight".
