Which phase of the ADM ensures that implementation projects conform to the defined architecture?

Requirements Management is an ongoing process that manages architectural requirements throughout the ADM, but it is not a specific phase for implementation conformance.

Phase D, Architecture Technology, is where the Technology Architecture is developed, not where implementation projects are governed for conformance.

Phase F, Migration Planning, focuses on creating detailed migration plans and implementation strategies, rather than the ongoing governance of project execution.

Phase G, Implementation Governance, is the ADM phase focused on ensuring architectural conformance during the implementation of solutions. It provides architectural oversight for all implementation, deployment, and operational activities, thereby ensuring that projects adhere strictly to the defined and agreed-upon architecture.

Phase H, Architecture Change Management, addresses managing changes to the architecture after it has been deployed, not the initial conformance of implementation projects.
