TOGA Classroom Series - M4 adm-phases-(preliminary-a)

This document summarizes the preliminary phase and phase A of the ADM (Architecture Development Method) framework. The preliminary phase involves defining the scope of the enterprise architecture initiative, establishing governance frameworks, and identifying existing architecture assets. The key outputs are an organizational model, tailored architecture framework, and initial architecture repository. Phase A focuses on developing a high-level aspirational architecture vision and obtaining approval for a statement of architecture work through business scenarios and risk analysis. The vision and statement of work define the program to develop and deploy the target architecture.
