The Open Group Architecture Framework (TOGAF) is a framework - a detailed method and a set of supporting tools - for developing an enterprise architecture.
TOGAF was developed by members of The Open Group, working within the Architecture Forum. The original development of TOGAF Version 1 in 1995 was based on the Technical Architecture Framework for Information Management (TAFIM), developed by the US Department of Defense (DoD).
Structure of the TOGAF Document
There are four main parts to the TOGAF document:
Part I : Introduction
This Part provides a high-level introduction to some of the key concepts behind enterprise architecture and in particular the TOGAF approach.
Part II : Architecture Development Method
This is the core of TOGAF. It describes the TOGAF Architecture Development Method (ADM) - a step-by-step approach to developing an enterprise architecture.
Part III : Enterprise Continuum
This Part describes the TOGAF Enterprise Continuum, a virtual repository of architecture assets, which includes the TOGAF Foundation Architecture, and the Integrated Information Infrastructure Reference Model (III-RM).
Part IV : Resources
This Part comprises the TOGAF Resource Base - a set of tools and techniques available for use in applying TOGAF and the TOGAF Architecture Development Method
