The Open Group Architecture Framework Version 9.1†
- EAフレームワーク(EA Framework)
- The Open Group
TOGAF is a framework - a detailed method and a set of supporting tools - for developing an enterprise architecture. It may be used freely by any organization wishing to develop an enterprise architecture for use within that organization (see 4.5.1 Conditions of Use).
TOGAF is developed and maintained by members of The Open Group, working within the Architecture Forum (refer to www.opengroup.org/architecture). 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). 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 US Government investment.
Starting from this sound foundation, the members of The Open Group Architecture Forum have developed successive versions of TOGAF and published each one on The Open Group public web site.
If you are new to the field of enterprise architecture and/or TOGAF, you are recommended to read the Executive Overview (refer to 1.2 Executive Overview), where you will find answers to questions such as:
- What is an enterprise?
- Why do I need an enterprise architecture?
- Why do I need TOGAF as a framework for enterprise architecture?
