How many phases are there in the TOGAF ADM?

The Architecture Development Method (ADM) in TOGAF consists of eight distinct phases. These phases provide a structured approach to developing and managing enterprise architecture. Each phase has specific objectives, deliverables, and requirements, allowing organizations to methodically move from an initial vision to implementation.

The eight phases are:

1. Preliminary Phase: Establishes the architecture framework and defines the key stakeholders.

2. Phase A: Architecture Vision: Develops a high-level aspirational vision of the capabilities and business value to be delivered.

3. Phase B: Business Architecture: Focuses on the business processes and organization of the enterprise.

4. Phase C: Information Systems Architectures: Divided into two parts, this phase captures the data architecture and application architecture.

5. Phase D: Technology Architecture: Details the software and hardware necessary to support the deployment of business, data, and application architectures.

6. Phase E: Opportunities and Solutions: Identifies potential solutions and evaluates them against the architecture vision.

7. Phase F: Migration Planning: Creates an actionable plan for transition from the current state to the desired state.

8. Phase G: Implementation Governance: Ensures that the architecture
