TOGAF is an acronym for The Open Group Architecture Framework. It is an enterprise architectural framework tool used for assisting in the acceptance, production, use, and maintenance of architectures. TOGAF is based on an iterative process model supported by best practices and a reusable set of existing architectural assets. It is developed and maintained by The Open Group Architecture Forum.
The first version was developed in 1995 by the US Department of Defense Technical Architecture Framework for Information Management (TAFIM) and subsequent versions of TOGAF have been developed by the Open Group Architecture Forum at regular intervals. Each version is published on The Open Group public web site.
TOGAF can be used for developing a broad range of different enterprise architectures. TOGAF compliments and can be used in conjunction with other frameworks that are more focused on specific deliverables for particular vertical sectors such as Government, Telecommunications, Manufacturing, Defense, and Finance.
