Phase H: Architecture Change Management
Ensures that the architecture responds to the needs of the enterprise
The final step in the development of the four architecture domains
Create Architecture Definition Document
The version numbers used by the TOGAF standard as a convention to denote a high-level outline of an architecture
Version 0.1
The recommended information areas managed by a governance repository.
The ADM supports the concept of iteration at three levels.
Architecture Development Method Activities by Phase
Preliminary Phase
Requirements Management
Every stage of a TOGAF project is based on and validates business requirements. Requirements are identified, stored, and fed into and out of the relevant ADM phases, which dispose of, address, and prioritize requirements.
Phase A: Architecture Vision
Phase B: Business Architecture, Phase C: Information Systems Architectures (Application & Data), Phase D: Technology Architecture
Develop architectures in four domains.
Phase E: Opportunities & Solutions
Phase F: Migration Planning
Develop a detailed Implementation and Migration Plan that addresses how to move from the Baseline to the Target Architecture.
Phase G: Implementation Governance
Phase H: Architecture Change Management
Provide continual monitoring and a change management process to ensure that the architecture responds to the needs of the enterprise and maximizes the value of the architecture to the business.

Version 0.1
Indicates that a high-level outline of the architecture is in place.
Version 1.0
Indicates a formally reviewed, detailed architecture.
The practical implementation of the Enterprise Continuum
Take the form of an Architecture Repository
Architecture Repository
Includes reference architectures, models, and patterns that have been accepted for use within the enterprise, and actual architectural work done previously within the enterprise.
The application of the ADM is supported by
An extended set of resources – guidelines, templates, checklists, and other detailed materials
Main reasons to constrain (or restrict) the scope of the architectural activity to be undertaken
