Phase A: Architecture Vision is the first phase of the Architecture Development Method (ADM) cycle, which is the core of the TOGAF standard. The main purpose of this phase is to define the scope and approach of the architecture development, and to create the Architecture Vision, which is a high-level description of the desired outcomes and benefits of the proposed architecture. To achieve this purpose, this phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements, and establishing the business goals and drivers that motivate the architecture work. This phase also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process.

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.

Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions.

According to the TOGAF Standard, 10th Edition, a transformation readiness assessment is a technique that evaluates the preparedness of the organization to undergo a change, and identifies the actions needed to increase the likelihood of a successful outcome. A transformation readiness assessment can be conducted in Phase E: Opportunities and Solutions, and the actions resulting from it can be dealt with in Phase F: Migration Planning 1. In Phase E, the transformation readiness assessment can help to identify the major implementation challenges and risks, and to define the critical success factors and key performance indicators for the architecture project. In Phase F, the actions resulting from the transformation readiness assessment can help to develop a detailed and realistic migration plan, and to address the gaps, issues, and dependencies that may affect the transition to the target architecture 1.
