TOGAF Architecture Development Method (ADM)

Phases within the ADM are as follows:

• The Preliminary Phase describes the preparation and initiation activities required to prepare to meet the business directive for a new enterprise architecture, including the definition of an Organization-Specific Architecture framework and the definition of principles.
• Phase A: Architecture Vision describes the initial phase of an architecture development cycle. It includes information about defining the scope, identifying the stakeholders, creating the Architecture Vision, and obtaining approvals.
• Phase B: Business Architecture describes the development of a Business Architecture to support an agreed Architecture Vision.
• Phase C: Information Systems Architectures describes the development of Information Systems Architectures for an architecture project, including the development of Data and Application Architectures.
• Phase D: Technology Architecture describes the development of the Technology Architecture for an architecture project.
• Phase E: Opportunities & Solutions conducts initial implementation planning and the identification of delivery vehicles for the architecture defined in the previous phases.
• Phase F: Migration Planning addresses the formulation of a set of detailed sequence of transition architectures with a supporting Implementation and Migration Plan.
• Phase G: Implementation Governance provides an architectural oversight of the implementation.
• Phase H: Architecture Change Management establishes procedures for managing change to the new architecture.
• Requirements Management examines the process of managing architecture requirements throughout the ADM.
