Comprehensive Guide to Aligning TOGAF ADM with the Architecture Content Framework

Introduction

The TOGAF (The Open Group Architecture Framework) Architecture Development Method (ADM) is a proven approach for developing and managing the lifecycle of an enterprise architecture. The Architecture Content Framework provides a structured way to describe and organize the architectural work products developed during the ADM phases. This guide will explain how the TOGAF ADM aligns with the Architecture Content Framework, detailing the relationship between them and providing practical examples.

Understanding the TOGAF ADM

The TOGAF ADM consists of several phases, each focusing on different aspects of architecture development:

  1. Preliminary Phase: Preparation and initiation of the architecture development process.
  2. Architecture Vision: Defining the scope, stakeholders, and high-level business value.
  3. Business Architecture: Developing the business architecture to support the architecture vision.
  4. Information Systems Architectures: Developing the data and application architectures.
  5. Technology Architecture: Developing the technology architecture to support the deployment of core, mission-critical applications.
  6. Opportunities and Solutions: Identifying opportunities and developing the Architecture Roadmap.
  7. Migration Planning: Planning the implementation and migration to the new architectures.
  8. Implementation Governance: Governing the realization of the architecture.

The Architecture Content Framework

The Architecture Content Framework categorizes the inputs and outputs of each ADM phase, ensuring that all necessary components of the architecture are considered and addressed. It includes:

  1. Architecture Principles, Vision, and Requirements
  2. Architecture Definition
  3. Architecture Realization
