How many phases are there in the ADM?

The Architecture Development Method (ADM) is a central component of the TOGAF framework, and it consists of eight distinct phases. These phases are designed to guide architects through the process of developing and managing an enterprise architecture. Each phase has specific objectives and deliverables that contribute to the overall architecture effort, including the preliminary phase, requirements, business architecture, information systems architecture, technology architecture, opportunities and solutions, migration planning, and implementation governance.

Understanding the eight phases is crucial for effectively applying the ADM in real-world scenarios. This structured methodology ensures that all aspects of the enterprise architecture are covered, fostering alignment between business and IT strategies while also enabling iterative development. Each phase builds upon the previous one, providing a comprehensive approach to architecture development that is flexible enough to adapt to various organizational needs.
