During which phase is stakeholder engagement primarily established?

The establishment of stakeholder engagement primarily occurs during Phase A of the Architecture Development Method (ADM) in TOGAF. During this phase, the architecture vision is developed, and it's crucial to identify the key stakeholders who will be involved in the architecture work. This involves understanding their needs, concerns, and the value they bring to the project.

In Phase A, the architecture vision is created, which necessitates engaging with stakeholders to ensure their perspectives are included and that their requirements are understood. This phase focuses on aligning the architecture goals with the business objectives, making stakeholder engagement essential to achieve a clear and aligned vision.

While the Preliminary Phase does lay the groundwork for project scope and initial stakeholder identification, it is during Phase A that a more thorough and structured engagement with stakeholders takes place, emphasizing their roles and contributions. Additionally, Phases G and H focus on implementation and governance of the architecture rather than the initial stakeholder engagement, which further solidifies why Phase A is the correct choice for establishing stakeholder engagement.
