Phase E: Opportunities & Solutions Knowledge-Based Study

Study notes

1. Phase E: Opportunities & Solutions

   In the TOGAF Standard, 10th Edition, Phase E: Opportunities & Solutions marks the transition from architecture definition to implementation planning. It concentrates on how the Target Architecture will be delivered across discrete increments and work packages.

   Key Objectives

   • Generate the initial complete version of the Architecture Roadmap based upon the gap analysis results from Phases B, C, and D.
   • Determine whether an incremental approach is required, and if so, define suitable Transition Architectures.
   • Identify candidate work packages and evaluate strategic partner or solution options to satisfy identified gaps.
   • Consolidate the gap analysis findings across business, data, application, and technology domains to synthesize logical implementation projects.

   Applying Phase E to the Enterprise Architecture Capability

   When the enterprise applies the TOGAF Architecture Development Method (ADM) to establish or evolve its own Enterprise Architecture Capability, Phase E focuses on the tangible realization of that capability within governance structures.

   Core Focus Areas

   • Capability Increments: Structuring the deployment of the EA practice across progressive maturity levels, establishing governance bodies, tools, repositories, and skill development in measurable stages.
   • Architecture Governance Alignment: Mapping EA capability work packages to corporate governance, portfolio management, and operational decision-making frameworks.
   • Make, Buy, or Partner Decisions: Evaluating whether EA tooling, frameworks, or competencies should be acquired, built internally, or augmented via external specialized partners.

   Steps and Deliverables in Phase E

   Phase E synthesizes requirements and architecture definitions into practical delivery constructs.

   Primary Steps

   1. Determine Business Value and Constraints: Review corporate business drivers, implementation dependencies, and organizational constraints.
   2. Consolidate Gap Analysis Results: Combine the gap analyses across all architecture domains to identify shared dependencies and eliminate redundant initiatives.
   3. Define Work Packages: Group related gap resolutions into coherent projects, programs, or organizational change packages.
   4. Formulate Transition Architectures: Outline intermediate operational states that deliver continuous, measurable business value before reaching the Target Architecture.
   5. Synthesize the Architecture Roadmap: Create a baseline chronological plan showing the progression from the Baseline Architecture to the Target Architecture.

   Key Outputs

   • Architecture Roadmap (initial formal version)
   • Candidate Work Packages
   • Transition Architecture Definitions
   • Implementation and Migration Strategy

   Knowledge Check

   Review the following practice question to test your understanding of Phase E within the TOGAF ADM cycle.

   Question: What is a primary objective of Phase E: Opportunities & Solutions when establishing an Enterprise Architecture Capability?

   • A: Formulating the definitive Architecture Contract to govern operational implementation projects.
   • B: Synthesizing the gap analysis across domains to produce the initial Architecture Roadmap and Transition Architectures.
   • C: Establishing the Architecture Board and authorizing the Architecture Vision statement.
   • D: Conducting post-implementation reviews to assess the operational baseline against service-level agreements.

   Correct Answer: B

   Explanation: Phase E focuses on evaluating implementation options, grouping gaps into work packages, and formulating the initial complete Architecture Roadmap along with any necessary Transition Architectures. Formulating the Architecture Contract occurs primarily in Phase G, defining the Architecture Vision belongs to Phase A, and post-implementation reviews occur in Phase H and operational governance.
