The Implementation Governance Model is a key artifact produced during the TOGAF Architecture Development Method (ADM). Its primary purpose is to define the framework, processes, roles, and responsibilities for governing the implementation of the architecture. This model ensures that the implementation projects conform to the defined Target Architecture and provides a structured mechanism for the project to transition from the implementation phase into the ongoing, operational Architecture Governance framework established by the enterprise.

A. Migration Plan: This plan details the sequence of projects and activities required to transition from the Baseline to the Target Architecture, focusing on the "how-to" of migration, not the governance structure.

B. Transition Plan: This is a general term, often part of the Migration Plan, that outlines the steps for moving to the new state. It does not specifically define the governance handover process.

D. Implementation Strategy: This is a high-level approach that outlines the overall method for implementing the architecture (e.g., phased rollout, big bang), but it is not the detailed governance model itself.
