The document outlines the phases of the TOGAF (The Open Group Architecture Framework) architecture development method (ADM). It includes 8 phases: Preliminary Phase, Phase A (Architecture Vision), Phase B (Business Architecture), Phase C (Information Systems Architectures), Phase D (Technology Architecture), Phase E (Opportunities and Solutions), Phase F (Migration Planning), Phase G (Implementation Governance), and Phase H (Architecture Change Management). Each phase involves several steps to scope the enterprise impact, establish teams and principles, develop baseline and target architectures, identify gaps and solutions, create roadmaps and plans, and govern implementation and change management.

Define candidate roadmap components 6. Resolve impacts across the Architecture Landscape 7. Conduct formal stakeholder review 8. Finalize the Architecture 9. Create Architecture Definition Document Phase E: Opportunities and Solutions 1. Determine/confirm key corporate change attributes 2. Determine business constraints for implementation 3. Review and consolidate gap analysis results from Phases B to D 4. Review consolidated requirements across related business functions 5. Consolidate and reconcile interoperability requirements 6. Refine and validate dependencies 7. Confirm readiness and risk for business transformation 8. Formulate Implementation and Migration Strategy 9. Identify and group major work packages 10. Identify Transition Architectures 11. Create Architecture Roadmap & Implementation and Migration Plan Phase F: Migration Planning 1. Confirm management framework interactions for Implementation and Migration Plan 2. Assign a business value to each work package 3. Estimate resource requirements, project timings, and availability/delivery vehicle 4. Prioritize the migration projects through the conduct of a cost/benefit assessment and risk validation 5. Confirm Architecture Roadmap and update Architecture Definition Document 6. Complete the Implementation and Migration Plan 7. Complete the development cycle and document lessons learned Phase G: Implementation Governance 1. Confirm scope and priorities for deployment with development management 2. Identify deployment resources and skills 3. Guide development of solutions deployment 4. Perform enterprise architecture compliance reviews 5. Implement business and IT operations 6. Perform post-implementation review and close the implementation Phase H: Architecture Change Management 1. Establish value realization process 2. Deploy monitoring tools 3. Manage risks 4. Provide analysis for architecture change management 5. Develop change requirements to meet performance targets 6. Manage governance process 7. Activate the process to implement change Requirements Management 1. Identify/document requirements 2. Baseline requirements 3. Monitor baseline requirements 4. Identify changed requirement; remove, add, modify, and re-assess priorities 5. Identify changed requirement and record priorities; identify and resolve conflicts; generate requirements impact statements 6. Assess impact of changed requirement on current and previous ADM phases 7. Implement requirements arising from Phase H 8. Update the requirements repository 9. Implement change in the current phase 10. Assess and revise gap analysis for past phases N112 Reference Card: TOGAF 9.1 ADM Steps TOGAF 9.1 ADM Steps Reference Copyright © 2011 The Open Group.
