Phase A: Architecture Vision in TOGAF ADM

Introduction

Phase A of the TOGAF Architecture Development Method (ADM) is the initial phase focused on defining the scope, identifying stakeholders, creating the Architecture Vision, and obtaining necessary approvals. This phase sets the foundation for the entire architecture development process by establishing a clear vision and securing stakeholder buy-in.

Objectives and Steps

1. Develop a High-Level Aspirational Vision

Objective: Create a high-level vision of the capabilities and business value to be delivered through the proposed Enterprise Architecture.

Steps:

• Identify Stakeholders, Concerns, and Business Requirements: Engage with stakeholders to understand their needs and concerns. Document business requirements that the architecture must address.
• Confirm and Elaborate Business Goals, Business Drivers, and Constraints: Clarify the business goals, drivers, and any constraints that may impact the architecture.
• Evaluate Capabilities: Assess the current capabilities of the organization and identify gaps that need to be addressed.
• Assess Readiness for Business Transformation: Evaluate the organization’s readiness for the changes that the new architecture will bring.
• Define the Scope: Clearly define the scope of the architecture project, including what will be included and excluded.
• Confirm and Elaborate Architecture Principles: Ensure that the architecture principles, including business principles, are well-defined and agreed upon.
• Develop the Architecture Vision: Create a comprehensive Architecture Vision that outlines the desired future state of the enterprise architecture.
• Define the Target Architecture Value Propositions and KPIs: Identify the value propositions of the target architecture and define Key Performance Indicators (KPIs) to measure success.
• Identify Business Transformation Risks and Mitigation Activities: Recognize potential risks associated with the business transformation and develop mitigation strategies.

2. Obtain Approval for a Statement of Architecture Work

Objective: Secure approval for a Statement of Architecture Work that defines the program of works to develop and deploy the architecture.

Steps:

• Develop Statement of Architecture Work: Create a detailed Statement of Architecture Work that outlines the scope, objectives, and deliverables of the architecture project.
• Secure Approval: Present the Statement of Architecture Work to stakeholders and obtain their approval to proceed with the architecture development.

Inputs and Outputs

Inputs

1. Request for Architecture Work: The initial request that triggers the architecture development process.
2. Business Principles, Business Goals, and Business Drivers: Key business information that guides the architecture development.
3. Organizational Model for Enterprise Architecture: The organizational structure and roles involved in the Enterprise Architecture.
4. Tailored Architecture Framework: The customized architecture framework, including methods, content, principles, and tools.
5. Populated Architecture Repository: Existing architecture documentation, including framework descriptions, architecture descriptions, and baseline descriptions.

Outputs

1. Approved Statement of Architecture Work: The approved document that outlines the scope, objectives, and deliverables of the architecture project.
2. Refined Statements of Business Principles, Business Goals, and Business Drivers: Clarified and detailed business information.
3. Architecture Principles: The guiding principles for the architecture development.
4. Capability Assessment: An evaluation of the organization’s current capabilities.
5. Tailored Architecture Framework: The customized architecture framework used for the project.
6. Architecture Vision: The comprehensive vision for the future state of the enterprise architecture.
7. Draft Architecture Definition Document: A preliminary document that may include baseline and/or target architectures.
8. Communications Plan: A plan for communicating the architecture vision and progress to stakeholders.
9. Additional Content Populating the Architecture Repository: New architecture documentation added to the repository.

Key Concepts

• Architecture Vision: A high-level aspirational vision of the capabilities and business value to be delivered through the Enterprise Architecture.
• Statement of Architecture Work: A document that defines the program of works to develop and deploy the architecture.
• Stakeholder Engagement: The process of identifying and engaging with stakeholders to understand their needs and concerns.
• Business Transformation: The changes that the new architecture will bring to the organization.
• Risk Mitigation: Strategies to identify and mitigate potential risks associated with the business transformation.

Conclusion

Phase A of the TOGAF ADM is critical for setting the foundation for the architecture development process. By developing a clear Architecture Vision and obtaining approval for the Statement of Architecture Work, organizations can ensure that their Enterprise Architecture initiatives are aligned with business goals and have the support of key stakeholders. This phase sets the stage for successful architecture development and deployment, driving business value and transformation.
