Draft Federal Information Processing Standards Publication 183 1993 December 21 Announcing the Standard for INTEGRATION DEFINITION FOR FUNCTION MODELING (IDEF0)

Federal Information Processing Standards Publications (FIPS PUBS) are issued by the National Institute of Standards and Technology after approval by the Secretary of Commerce pursuant to Section 111(d) of the Federal Property andAdministrative Services Act of 1949 as amended by the Computer Security Act of 1987, Public Law 100-235. 1. 2. Name of Standard. Integration Definition for Function Modeling (IDEF0). Category of Standard. Software Standard, Modeling Techniques.

3. Explanation. This publication announces the adoption of the Integration Definition Function Modeling (IDEF0) as a Federal Information Processing Standard(FIPS). This standard is based on the Air Force Wright Aeronautical Laboratories Integrated Computer- Aided Manufacturing (ICAM) Architecture, Part II, Volume IV - Function Modeling Manual (IDEF0), June 1981. This standard describes the IDEF0 modeling language (semantics and syntax), and associated rules and techniques, for developing structured graphical representations of a system or enterprise.Use of this standard permits the construction of models comprising system functions (activities, actions, processes, operations), functional relationships, and data (information or objects) that support systems integration. This standard is the reference authority for use by system or enterprise modelers required to utilize the IDEF0 modeling technique, by implementors in developing tools forimplementing this technique, and by other computer professionals in understanding the precise syntactic and semantic rules of the standard. 4. Approving Authority. Secretary of Commerce.

Objectives. The primary objectives of this standard are:

a. To provide a means for completely and consistently modeling the functions (activities, actions, processes, operations) required by a system or enterprise, and the functionalrelationships and data (information or objects) that support the integration of those functions; b. To provide a modeling technique which is independent of Computer-Aided Software Engineering (CASE) methods or tools, but which can be used in conjunction with those methods or tools; c. To provide a modeling technique that has the following characteristics: Generic (for analysis of systems ofvarying purpose, scope and complexity); Rigorous and precise (for production of correct, usable models); Concise (to facilitate understanding, communication, consensus and validation); Conceptual (for representation of functional requirements rather than physical or organizational implementations); Flexible (to support several phases of the lifecycle of a project).
