Introduction

The Preliminary Phase of the TOGAF Architecture Development Method (ADM) is crucial for preparing and initiating activities required to establish an Enterprise Architecture Capability. This phase includes defining an organization-specific architecture framework, developing architecture principles, and identifying business principles, goals, and drivers. The following guide outlines the steps to complete the key deliverables of the Preliminary Phase.

Objectives

The primary objectives of the Preliminary Phase are to:

  1. Define the Architecture Capability desired by the organization.
  2. Establish the Architecture Capability.
  3. Scope the enterprise organizations impacted.
  4. Confirm governance and support frameworks.
  5. Define and establish the Enterprise Architecture team and organization.
  6. Identify and establish Architecture Principles.
  7. Tailor the TOGAF framework and, if any, other selected architecture frameworks.
  8. Develop strategy and implementation plans for tools and techniques.

Deliverables

1. Tailored Architecture Framework

Objective: Customize the TOGAF framework to meet the specific needs of the organization.

Steps:

  1. Review Organizational Context: Understand the organizational structure, culture, and current processes.
  2. Identify Framework Components: Determine which components of the TOGAF framework are relevant to the organization.
  3. Customize Framework: Tailor the framework to align with the organization’s goals and requirements.
  4. Document Framework: Create a detailed document outlining the tailored architecture framework.
  5. Get Approval: Present the tailored framework to stakeholders and obtain approval.

2. Organizational Model for Enterprise Architecture

Objective: Define the organizational model for Enterprise Architecture, including roles, responsibilities, and governance structures.

Steps:

  1. Identify Roles and Responsibilities: Define the roles and responsibilities of the Enterprise Architecture team.
  2. Establish Governance Structures: Develop governance structures to oversee the architecture development process.
  3. Create Organizational Chart: Document the organizational model in an organizational chart.
  4. Communicate Model: Share the organizational model with stakeholders to ensure understanding and buy-in.
  5. Implement Model: Put the organizational model into practice within the organization.

3. Architecture Principles

Objective: Establish guiding principles for the architecture development process.

Steps:

  1. Review Business Principles: Ensure that architecture principles align with business principles.
  2. Develop Principles: Create a set of architecture principles that will guide the development process.
  3. Document Principles: Write a detailed document outlining the architecture principles.
  4. Get Approval: Present the principles to stakeholders and obtain approval.
  5. Communicate Principles: Share the principles with the Enterprise Architecture team and other relevant stakeholders.

4. Business Principles, Goals, and Drivers

Objective: Identify and document the business principles, goals, and drivers that will influence the architecture development process.

Steps:

  1. Gather Input: Collect information on business principles, goals, and drivers from key stakeholders.
  2. Analyze Input: Analyze the gathered information to identify key business principles, goals, and drivers.
  3. Document Findings: Create a detailed document outlining the business principles, goals, and drivers.
  4. Get Approval: Present the document to stakeholders and obtain approval.
  5. Communicate Findings: Share the findings with the Enterprise Architecture team and other relevant stakeholders.

5. Request for Architecture Work

Objective: Develop a Request for Architecture Work that outlines the scope, objectives, and deliverables of the architecture development process.

Steps:

  1. Define Scope: Clearly define the scope of the architecture work.
  2. Identify Objectives: Outline the objectives of the architecture development process.
  3. List Deliverables: Document the expected deliverables of the architecture work.
  4. Create Request: Develop a formal Request for Architecture Work.
  5. Get Approval: Present the request to stakeholders and obtain approval.
  6. Communicate Request: Share the approved request with the Enterprise Architecture team and other relevant stakeholders.

Key Concepts

  • Tailored Architecture Framework: A customized version of the TOGAF framework that meets the specific needs of the organization.
  • Organizational Model for Enterprise Architecture: The organizational structure and roles involved in the Enterprise Architecture.
  • Architecture Principles: Guiding principles for the architecture development process.
  • Business Principles, Goals, and Drivers: The business principles, goals, and drivers that influence the architecture development process.
  • Request for Architecture Work: A formal request that outlines the scope, objectives, and deliverables of the architecture development process.

Conclusion

The Preliminary Phase of the TOGAF ADM is essential for establishing a solid foundation for the Enterprise Architecture Capability. By following the outlined steps and completing the key deliverables, organizations can ensure that their architecture development process is aligned with business goals and strategic drivers. This phase sets the stage for successful architecture development and deployment, driving business value and transformation.
