* 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.
