Which of the following documents is produced in Phase A as a response to the Request for Architecture Work?

In TOGAF, Phase A of the Architecture Development Method (ADM) focuses on establishing the architecture vision and creating a foundational framework for subsequent phases. One critical output of Phase A is the Statement of Architecture Work, which is developed as a response to a Request for Architecture Work.

The Statement of Architecture Work outlines the scope, objectives, and approach for the architecture activity that will be undertaken. It specifies the deliverables, milestones, and resources required, thereby providing a clear blueprint for the architecture work to be initiated. This document ensures that all stakeholders are aligned on what the architecture work will entail and how it will be managed.

The Architecture Contract, while important, is related to the governance of the architecture process and comes into play later in the ADM. The Architecture Definition Document is produced in later phases, detailing the architecture itself. The Requirements Impact Statement is typically involved in analyzing how requirements may change due to architectural decisions, but is not a primary output of Phase A. Therefore, the correct choice reflects the appropriate outcome of Phase A's efforts in defining the scope and approach to the architecture work.
