During which phase of the TOGAF ADM is the Architecture Vision document typically refined?

The refinement of the Architecture Vision document occurs during the Opportunities and Solutions phase of the TOGAF Architecture Development Method (ADM). This phase is crucial for expanding upon the initial vision established in the preliminary phases. Here, the architects work on identifying implementation delivery vehicles that align with the Architecture Vision, ensuring that the strategic goals outlined are feasible and actionable.

During this phase, practical opportunities for realizing the vision are explored, and the architecture elements needed to achieve those outcomes are detailed. This results in a more comprehensive understanding of how the architecture will be implemented, allowing for adjustments and refinements based on insights gained during the exploration of opportunities and potential solutions.

The other phases, while they have their own important roles in the TOGAF ADM, do not primarily focus on the refinement of the Architecture Vision document in the way the Opportunities and Solutions phase does. Requirements Management is more about continuously managing changing requirements, Architecture Change Management focuses on adapting existing architectures, and Implementation Governance emphasizes overseeing the architecture execution rather than refining the vision itself.
