Introduction

Enterprise architecture (EA) is a critical discipline that helps organizations align their business strategies with their IT infrastructure. Two prominent frameworks in this field are ArchiMate, a modeling language, and TOGAF (The Open Group Architecture Framework), which includes the Architecture Development Method (ADM). This guide explores how ArchiMate enhances the TOGAF ADM phases by providing a standardized, visual modeling language that complements the ADM’s structured process, improving clarity, communication, and alignment of enterprise architecture artifacts throughout the development lifecycle.

How ArchiMate Enhances Each TOGAF ADM Phase

Phase A: Architecture Vision

ArchiMate’s Motivation Layer models stakeholders, drivers, goals, and requirements, helping to capture and visualize the high-level architectural vision and scope. This visual representation supports stakeholder understanding and buy-in by clearly illustrating the intended changes and their business impact.

Example:

  • Stakeholders: Identify key stakeholders such as business executives, IT managers, and end-users.
