IDEF Family of Methods

A Structured Approach to Enterprise Modeling & Analysis

IDEF.com was developed and is maintained by Knowledge Based Systems, Inc. (KBSI), the developers of the next generation IDEF methods: the IDEF3 Process Flow and Object State Description Capture Method, the IDEF4 Object-Oriented Design Method, and the IDEF5 Ontology Description Capture Method. IDEF, initially abbreviation of ICAM Definition, renamed in 1999 as Integration DEFinition, refers to a family of modeling languages in the field of systems and software engineering. They cover a wide range of uses, from functional modeling to data, simulation, object-oriented analysis/design and knowledge acquisition. These definition languages were developed under funding from U.S. Air Force and are heavily used by them, as well as other military and United States Department of Defense (DoD) agencies, are also used by many corporation for business process capture and improvement.
