1. Introduction
The purpose of this guide is to provide a detailed framework for developing an end-to-end Target Architecture that aligns with an organization’s strategic objectives. This architecture will serve as a roadmap for change initiatives, governance boundaries, and value reporting criteria. The process will involve iterating through the Architecture Development Method (ADM) at both the Enterprise and EA Capability levels.
1.1 Importance of Enterprise Architecture (EA)
Enterprise Architecture is crucial for organizations that have been operating for years and are looking to adapt to changing business environments. It helps in aligning IT strategy with business goals, ensuring that technology investments support the overall mission of the organization.
2. Understanding the Context
2.1 Mapping to TOGAF ADM Phase
Phase H: Understand Context
- Review Existing Roadmap: Analyze the current strategic roadmap to identify existing initiatives and their alignment with business goals.
- Identify Gaps: Use SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) to infer gaps in the current architecture.
Example: A retail company may find that its existing roadmap lacks initiatives for e-commerce, which is critical in the current market.
2.2 Request for Architecture Work
Phase A: Request for Architecture Work
- Goals and Objectives: Define the organization’s goals, such as increasing market share or improving customer satisfaction.
- Operating Model: Understand the current operating model and how it supports or hinders strategic objectives.
Example: A healthcare organization may aim to improve patient care through better data integration across departments.
3. Perform Assessment and Analysis
3.1 Mapping to TOGAF ADM Phases
Phases B, C, and D: Perform Assessment and Analysis
- Current vs. Target Assessment: Evaluate the current operational levels of processes, applications, and technology against desired future states.
- Identify Candidate Architecture Building Blocks (ABBs): Determine potential components that can be developed or enhanced to bridge the gap.
Example: A financial institution may assess its current customer relationship management (CRM) system and identify the need for a more integrated solution that includes AI-driven analytics.
3.2 Organizational Structure and Stakeholder Matrix
- Stakeholder Identification: Create a matrix to identify key stakeholders and their concerns, ensuring that all voices are heard in the architecture process.
Example: In a manufacturing company, stakeholders may include production managers, IT staff, and supply chain partners.
4. Define Approach to Target State
4.1 Mapping to TOGAF ADM Phases
Phases B, C, and D: Define Approach to Target State
- Specification and Work Packages: Develop detailed specifications for each identified gap and create work packages to address them.
- Candidate Organization and Operating Models: Propose new organizational structures and operating models that align with the target architecture.
Example: A tech startup may decide to adopt an agile operating model to enhance its product development cycle.
4.2 Requirements Management
- Populate EA Repository: Document all requirements and specifications in an EA repository for future reference and governance.
5. Finalize Architecture Vision/Target State
5.1 Mapping to TOGAF ADM Phases
Phase F: Finalize Architecture Vision/Target State
- Complete Roadmap: Develop a comprehensive roadmap that outlines the steps needed to achieve the target architecture.
- Governance Model: Define a governance model that ensures compliance and oversight throughout the implementation process.
Example: A telecommunications company may create a roadmap that includes phases for network upgrades, customer service enhancements, and regulatory compliance.

This table summarizes the key phases, activities, objectives, and examples of the architecture development process to support strategy.
6. Conclusion
The architecture to support strategy is a dynamic and iterative process that requires continuous assessment and adaptation. By following the TOGAF ADM framework, organizations can ensure that their architecture aligns with strategic goals, addresses gaps, and provides a clear path for future initiatives.
6.1 Key Takeaways
- Iterative Process: The architecture development process is not linear; it requires revisiting phases as new information and challenges arise.
- Stakeholder Engagement: Involving stakeholders at every stage is crucial for ensuring that the architecture meets the needs of the organization.
- Documentation and Governance: Maintaining thorough documentation and a strong governance model is essential for the successful implementation of the target architecture.
By adhering to these principles and utilizing the TOGAF ADM framework, organizations can effectively navigate the complexities of enterprise architecture and drive meaningful change.
