A Comprehensive Guide for TOGAF ADM Phase E: Opportunities and Solutions (Part 6)

Introduction:

The Opportunities and Solutions phase (Phase E) within the TOGAF ADM is a pivotal stage in the architectural development process. This phase marks a transition from strategic planning to practical implementation, focusing on evaluating options, identifying strategic parameters, and formulating a comprehensive strategy for introducing the Target Architecture.

In this guide, we delve into the intricacies of Phase E, exploring its objectives, activities, inputs, steps, and outputs, providing a holistic understanding of how organizations can navigate the complex journey from architectural vision to tangible implementation.

Objectives:

1. Evaluate and Select Implementation Options:
   • Assess different implementation options to determine the most suitable for the enterprise architecture.
2. Identify Strategic Parameters for Change:
   • Define the key parameters that will drive strategic changes within the organization.
3. Assess Dependencies, Costs, and Benefits:
   • Analyze dependencies between projects, evaluate costs, and quantify benefits to make informed decisions.
4. Generate Implementation and Migration Strategy and Plan:
   • Develop a comprehensive strategy and plan for implementing the Target Architecture.

Overview of Activities:

1. Logical Grouping of IT Activities:
   • Logically group IT activities into project work packages, ensuring coherence and efficiency.
2. Top-Down Identification of Opportunities and Solutions:
   • Identify opportunities and solutions from a top-down perspective based on prior architecture work.
3. Dependency Analysis and Critical Path:
   • Create an implementation and migration strategy supported by dependency analysis to identify critical paths.
4. Incremental Transition Architectures:
   • Determine the number of increments needed to move from the baseline to the target architecture, with each increment considered a Transition Architecture.

Inputs:

1. Architecture Reference Materials
2. Product Information
3. Request for Architecture Work
4. Capability Assessment
5. Communications Plan

14. Draft Architecture Requirements Specification
15. Change Requests

Steps of Opportunities and Solutions Phase:

1. Determine Key Corporate Change Attributes:
   • Create an Implementation Factor Assessment and Deduction Matrix tying corporate culture to the best implementation approach.
2. Determine Business Constraints:
   • Identify business drivers that may constrain implementation and review strategic plans and Enterprise Architecture Maturity Assessment.
3. Consolidate Gap Analysis Results:
   • Integrate gap analysis results from Business, Information Systems, and Technology Architectures into a Consolidated Gaps, Solutions, and Dependencies Matrix.
4. Review IT Requirements:
   • Assess IT requirements to find the minimum set of functional requirements for effective Target Architecture implementation.
5. Consolidate Interoperability Requirements:
   • Consolidate and reconcile interoperability requirements based on previous phases.
6. Validate Dependencies:
   • Identify and validate dependencies related to constraints on Implementation and Migration Plans.
7. Confirm Readiness and Risk for Business Transformation:
   • Assess organizational readiness and adaptability to handle business transformation changes and associated risks.
8. Formulate Implementation and Migration Strategy:
   • Identify the strategic approach (Greenfield, Revolutionary, Evolutionary) and plan for introducing the new architecture.
9. Group Major Work Packages:
   • Identify, analyze, and classify major work packages as mainstream, contain, and replace systems.
10. Identify Transition Architectures:

• Identify Transition Architectures and Capabilities when an incremental approach is required.

11. Create Portfolio and Project Charters:

• Develop appropriate project documentation for each incremental work effort to realize Transition and Target Architectures.

Outputs:

1. Refined Versions of Architecture Deliverables:
   • Refined versions of Architecture Vision, Business, Information Systems, and Technology Architecture.
2. Consolidated Architecture Roadmap:
   • An integrated roadmap that consolidates architecture changes and timelines.
3. Capability Assessment:
   • An assessment of the organization’s capabilities to implement the proposed changes.
4. Transition Architecture(s):
   • Incremental architectures to facilitate the transition from the baseline to the target.
5. Implementation and Migration Plan:
   • A detailed plan outlining the strategy for implementing the Target Architecture.
