* According to the TOGAF Standard, Version 9.2, the ADM phases and their objectives are as follows1:
oPreliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.
oPhase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.
oPhase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.
oPhase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.
oPhase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.
oPhase 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.
oPhase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.
oPhase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.
oPhase H: Architecture Change Management: To monitor the changes in the business and technology environment, and to assess the impact and performance of the architecture.
oRequirements 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:
oObjective 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.
oObjective 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.
oObjective 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.
oObjective 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.
