IDEF0, short for ICAM Definition for Function Modeling, is a function modeling method for describing the decisions, actions and activities of an organization or system. It was derived from the Structured Analysis and Design Technique, SADT, developed by Douglas T. Ross and SofTech, and it was commissioned by the United States Air Force so that analysts could organize a system analysis and communicate with the customer through simple graphics. Functions are drawn as boxes, and the arrows that enter and leave each box are its inputs, controls, outputs and mechanisms. A model is decomposed in hierarchical levels, with three to six boxes at each level, and every function needs at least one control. IDEF0 belongs to the IDEF family of modeling languages that grew from the Air Force ICAM program in the 1970s and early 1980s, and the National Institute of Standards and Technology released it as a standard for function modeling in FIPS Publication 183 in December 1993.
