Welcome to TOGAF - The Open Group Architectural Framework.

TOGAF is a framework - a detailed method and a set of supporting tools - for developing an IT architecture. It is described in a set of documentation published by The Open Group on its public web server, and may be used freely by any organization wishing to develop an information systems architecture for use within that organization. (See specific conditions of use.)

TOGAF was developed by The Open Group's own members, 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. The DoD gave The Open Group explicit permission and encouragement to create TOGAF by building on the TAFIM, which itself was the result of many years of development effort and many millions of dollars of U.S. government investment.

Starting from this sound foundation, the members of The Open Group's Architecture Forum have developed successive versions of TOGAF each year and published each one on The Open Group's public web site.

If you are new to the field of IT architecture and/or TOGAF, you may find it worthwhile to read the set of Frequently Asked Questions, where you will find answers to questions such as:

For a longer introduction to TOGAF (but one still readable within a few minutes), you are recommended to read the TOGAF Executive Overview, which focuses on the business benefits of IT Architecture and how TOGAF can help deliver them.
