Which phase of the ADM focuses on the governance and management of the Architecture Contracts that cover the overall implementation and deployment process?

Requirements Management is an ongoing process throughout the ADM, not a distinct phase focused on implementation governance of contracts.

Phase E, Opportunities & Solutions, focuses on identifying delivery vehicles and creating an initial implementation plan, not on the governance of implementation contracts.

Phase F, Migration Planning, focuses on creating detailed implementation and migration plans, not the ongoing governance during implementation.

Phase G, Implementation Governance, is the ADM phase that focuses on providing architectural oversight of the implementation and deployment projects. This includes ensuring compliance with the defined architecture and managing the Architecture Contracts which guide the overall implementation process.

Phase H, Architecture Change Management, focuses on managing changes to the deployed architecture, not the governance of initial implementation contracts.
