In TOGAF, what is the primary purpose of the Architecture Vision phase?

The primary purpose of the Architecture Vision phase in TOGAF is to communicate the desired outcome of the architecture development. This phase serves as a foundational step where the overall vision for the architecture is articulated, outlining what the organization aims to achieve through its architecture initiatives. By clearly defining the vision, stakeholders can understand the goals, context, and significance of the architectural endeavor, which helps to align efforts and expectations.

In this phase, the architecture vision plays a crucial role in ensuring that all parties involved have a shared understanding of the intended architecture and its implications for the organization. It sets the direction for subsequent phases of architecture development by establishing a clear picture of the required capabilities and conditions for success.

While aspects like establishing design principles, defining roles, and assessing risks are important in the overall architecture framework, they are not the primary focus during the Architecture Vision phase. Instead, these elements might be addressed in later phases as the architecture is fleshed out and implemented, following the initial vision. Thus, the emphasis on communicating the desired outcome is key to building consensus and guiding the architecture development process effectively.
