During which ADM phase is the stakeholder communication plan developed?

The development of the stakeholder communication plan occurs during the Preliminary Phase of the Architecture Development Method (ADM) in TOGAF. This phase focuses on establishing the architecture framework and principles that will guide the development of the architecture. It is essential for engaging stakeholders early in the process to ensure their needs and expectations are understood and addressed throughout the architecture development cycle.

Establishing a clear communication plan is crucial because it helps facilitate ongoing dialogue with stakeholders, ensuring that they remain informed and can provide input as the architecture evolves. This groundwork sets the stage for successful engagement, which is vital for the acceptance and implementation of the architecture later in the process.

In contrast, the other phases mentioned, such as the Architecture Vision phase, focus more on developing a vision and scope for the architecture rather than on communication plans specifically. The Architecture Implementation phase is concerned with the actual execution of the architecture without the initial groundwork of stakeholder communication. Finally, the Architecture Change Management phase deals with managing changes to the architecture after it has been established, rather than planning how to communicate with stakeholders from the outset.
