Which phase of the ADM focuses on the architecture vision?

Phase A of the Architecture Development Method (ADM) in TOGAF specifically concentrates on establishing the architecture vision. This phase is crucial as it defines the high-level goals and objectives of the architecture initiative, ensuring that the architecture aligns with the strategic direction of the organization.

During this phase, stakeholders are engaged to gather requirements and expectations, leading to a shared understanding of the architecture vision among all parties involved. Additionally, a key outcome of Phase A is the identification of potential risks and constraints, as well as the establishment of a framework that will guide the subsequent phases of the ADM.

By focusing on the architecture vision, Phase A sets the groundwork for ensuring that the entire architecture development process effectively addresses the needs of the business and supports its goals. Thus, it is the foundation upon which all other phases are built, making it a pivotal aspect of the TOGAF framework.
