Which of the ADM phases includes the objective of establishing the organizational model for Enterprise Architecture?

The Preliminary Phase of the Architecture Development Method (ADM) in TOGAF is critical because it sets the foundation for all subsequent phases of architecture development. During this phase, one of the key objectives is to establish the organizational model for Enterprise Architecture. This involves defining the architecture team, establishing roles and responsibilities, and ensuring that there is a clear understanding of the organization's architecture framework and principles.

This phase focuses on preparing the organization for successful architecture development by aligning stakeholders, establishing governance processes, and confirming that the appropriate resources are in place to support the architecture efforts. By doing so, the organization ensures that it is ready to engage in the more detailed phases of the ADM that will build upon this organizational framework. Understanding this context is crucial as it highlights the importance of the Preliminary Phase in guiding the overall architecture initiative effectively. Other phases such as Phase A (Architecture Vision) and further detailed phases focus on specific areas of architecture development rather than setting up the overall organizational context.
