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

The Implementation Governance Model is the formal framework established to oversee the implementation of the architecture. It defines the roles, responsibilities, processes, and decision-making structures required to ensure the project adheres to the specified Target Architecture. A key function of this model is to manage the transition from project-specific governance to the enduring, operational Architecture Governance framework of the enterprise. This ensures that architectural compliance and control are maintained seamlessly as the project moves from development into its operational lifecycle.

A. Implementation Strategy: This outlines the high-level approach for the project but lacks the specific governance framework and handover procedures.
C. Transition Plan: This focuses on the sequence and dependencies of projects to achieve the Target Architecture, not the governance transition itself.
D. Migration Plan: This is a detailed technical plan for moving systems and data; it is a component of the overall transition, not the governance mechanism.

1. The Open Group, "TOGAF® Standard, 10th Edition," 2022. In Chapter 12, "Phase G: Implementation Governance," Section 12.1 Objectives states the goal is to "Ensure that the implementation project conforms to the Target Architecture" and "Perform appropriate Architecture Governance functions for the solution". This phase is where the governance transition is managed.

2. The Open Group, "TOGAF® Standard, 10th Edition," 2022. Chapter 12, "Phase G: Implementation Governance," Section 12.4 Outputs, lists the "Implementation Governance Model (validated)" as a key artifact. This artifact formally documents the governance structure for the implementation and its integration with ongoing governance.

3. The Open Group, "TOGAF® Standard, 10th Edition," 2022. Chapter 20, "Architecture Governance," Section 20.1 Introduction, describes the overarching framework. The Implementation Governance Model acts as the bridge, ensuring project-level activities align with and transition smoothly into this enterprise-wide framework.
