TOGAF ADM Overview

TOGAF ADM is a critical part of the TOGAF Standard. It's been in use for many years and has proven reliable and effective for most enterprises. The goal of the model is to create an Enterprise Architecture that is in line with the organization's vision and needs while utilizing existing architectural assets and TOGAF elements.

What is the TOGAF ADM?

The TOGAF ADM entails moving to a particular or group of architectures that are more specific to an enterprise. The process takes advantage of the existing architecture and TOGAF Foundation Architecture elements. In so doing, an organization achieves maximum efficiency and productivity.


The Architecture Development Method (ADM) falls under 9 key Phases. Each aims at covering a specific role and completely describes the essential aspects. These include identifying and understanding the objectives, input requirement, necessary steps, and output. Following the phases or stages is critical to optimizing the potential of TOGAF ADM.

TOGAF ADM Phases Explained

In this section, we will explain the TOGAF ADM Phases establishing an enterprise architecture capability.

Preliminary Phase - Framework and Principles

The introductory, also known as the Preliminary Phase, is used to develop the enterprise architecture team. It focuses on the key issues or questions that a the enterprise architecture team must address. These include:

  • Who does it target?
  • Where to use it
  • How to use the model
  • Why do you need it

The above steps make the concept clearer to the stakeholder. It also makes application/ implementation and using it more straightforward. After understanding the preliminary phase, you'll be able to:

  • Define an organization or enterprise
  • Identify and understand the principal elements and critical drivers in an enterprise.
  • Describe the needs for architecture work
  • Define the principles that affect the architecture work
  • Identify the most feasible framework for the organization
  • Define how the different management frameworks connect
  • Assess enterprise architecture team's maturity

TOGAF ADM Phases Explained

In this section, we will explain the TOGAF ADM Phases focused on developing an enterprise architecture.

Phase A: Defining Architecture Vision

Understanding the vision of an enterprise helps to come up with the most viable structure. Receiving a Request for Architecture Work from a prospective stakeholder is the first step. Next is to go through it to understand the architecture scope and then come up with a suitable architecture vision that improves the organization. The final step is to obtain approvals to proceed with developing the enterprise architecture.

Phase B: Assessing the Business Architecture

This phase looks at the current business structure and what a stakeholder intends to achieve. The first step centers on things like organizational design, enterprise process, information flows, business capability, and strategic business planning. Proper assessment and understanding of this phase are critical.

Phase C: Developing Information Systems Architectures

With the information gathered in Phase B and a better understanding of the enterprise, the next step is to Information Systems Architecture development. It's very detailed and will focus on the Data and Applications. Both the Data Architecture Domain and the Application Architecture Domain are treated individually.

Phase D: Describing and Developing Technology Architecture

Identifying, describing, and developing the Technology Architecture is the next phase. It takes into account the following things:

  • Identifying viewpoints, goals, reference models, and tools
  • Describing and creating Baseline Technology Architecture
  • Describing and coming up with suitable Target Technology Architecture
  • Undertaking gap analysis
  • Defining roadmap elements
  • Resolving Architecture Landscape effects
  • Undertaking stakeholder review
  • Finalizing Technology Architecture
  • Coming up with Architecture Definition Document

Phase E: Identifying Opportunities and Solutions

The EA team identifies opportunities and looks for the best solutions to any arising or previous issues. The phase identifies key phases, change parameters, top-level projects, and more.

A firm helping an enterprise achieve the proper infrastructure will repeatedly use TOGAF ADM Cycle. Doing so ensures that the best model is achieved without leaving any core elements. The EA team invests in proven methods to accomplish this.

 Phase F: Creating a Migration Plan

Having a proper migration plan ensures a seamless transition. It incorporates all the essential elements and spells out the mode of implementation according to priority. Cost assessment, benefits, dependency evaluation, are some of the activities factored in.

Phase G: Governance Implementation 

The Implementation Governance phase focuses on implementing the changes in the Architecture Roadmap and Implementation Plan. Also, it takes into account helpful information from other implementation projects. Good architecture governance helps to manage a project successfully while experiencing minimal setbacks.

Phase H: Establishing Architecture Change Management

Architecture Change Management involves ensuring the benefits expected from the target enterprise architecture are being achieved. As well, we make sure the target architect applies to the organization's current circumstances and ecosystem.

It specifies the key attributes, target point, and how to manage the exercise. The phase works with the Architecture Requirements Management process and is continuous.
