TOGAF ADM is a cyclical process consisting of several phases, each with specific objectives and deliverables. The key phases of TOGAF ADM are:

  1. Preliminary Phase: Preparation and initiation of the architecture effort.
  2. Architecture Vision: Defining the scope, stakeholders, and objectives of the architecture.
  3. Business Architecture: Developing a blueprint of the business strategy, governance, organization, and key business processes.
  4. Information Systems Architectures:
    • Data Architecture: Describing the structure of an organization’s logical and physical data assets.
    • Applications Architecture: Providing a blueprint for the individual application systems to be deployed.
  5. Technology Architecture: Describing the hardware, software, and network infrastructure needed to support the deployment of core, mission-critical applications.
  6. Opportunities and Solutions: Identifying and evaluating different implementation approaches.
  7. Migration Planning: Planning the transition from the baseline to the target architecture.
  8. Implementation Governance: Ensuring the architecture is implemented correctly.
  9. Architecture Change Management: Managing changes to the architecture.
