According to the TOGAF Standard, Version 9.2, the ADM phases and their objectives are as follows1:
Preliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.
Phase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.
Phase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.
Phase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.
Phase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.
Phase E: Opportunities and Solutions: To identify and evaluate the opportunities and solutions for implementing the target architecture, and to define the work packages and transition architectures.
Phase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.
Phase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.
Phase H: Architecture Change Management: To monitor the changes in the business and technology environment, and to assess the impact and performance of the architecture.
Requirements Management: To manage the architecture requirements throughout the ADM cycle, and to ensure alignment with the business requirements.
Based on the above definitions, we can match each objective with the corresponding phase as follows:
Objective 1: Ensure that the business value and cost of work packages and transition architectures is understood by key stakeholders. This objective is achieved in Phase H: Architecture Change Management, where the value realization and cost-benefit analysis of the architecture are performed2.
Objective 2: Ensure conformance with the Target Architecture by implementation projects. This objective is achieved in Phase F: Migration Planning, where the conformance requirements and criteria for the implementation projects are defined3.
Objective 3: Ensure that the architecture development cycle is maintained. This objective is achieved in Phase F: Migration Planning, where the architecture roadmap and iteration cycle are maintained3.
Objective 4: Ensure that the Architecture Governance Framework is executed. This objective is achieved in Phase G: Implementation Governance, where the architecture governance processes and procedures are applied to the implementation projects4.
