The Architecture Vision is an output of Phase A, outlining the high-level baseline and target architectures.

The Request for Architecture Work is the trigger for an ADM cycle and is typically issued by the sponsoring organization to the architecture organization.

This document is usually created in the Preliminary Phase or directly initiates Phase A.

The Statement of Architecture Work is an output of Phase A that defines the scope, resources, and deliverables for the specific architecture work being undertaken.
