Draft Federal InformationProcessing Standards Publication 1831993 December 21Announcing the Standard forINTEGRATION DEFINITION FOR FUNCTIONMODELING (IDEF0)Federal Information Processing Standards Publications (FIPS PUBS) are issued by the NationalInstitute of Standards and Technology after approval by the Secretary of Commerce pursuant toSection 111(d) of the Federal Property and Administrative Services Act of 1949 as amended bythe Computer Security Act of 1987, Public Law 100-235.1.Name of Standard.Integration Definition for Function Modeling (IDEF0).2.Category of Standard.Software Standard, Modeling Techniques.3.Explanation.This publication announces the adoption of the Integration DefinitionFunction Modeling (IDEF0) as a Federal Information Processing Standard (FIPS).

This standardis based on the Air Force Wright Aeronautical Laboratories Integrated Computer- AidedManufacturing (ICAM) Architecture, Part II, Volume IV - Function Modeling Manual (IDEF0),June 1981.This standard describes the IDEF0 modeling language (semantics and syntax), andassociated rules and techniques, for developing structured graphical representations of a systemor enterprise.

Use of this standard permits the construction of models comprising systemfunctions (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 requiredto utilize the IDEF0 modeling technique, by implementors in developing tools for implementingthis technique, and by other computer professionals in understanding the precise syntactic andsemantic rules of the standard.4.Approving Authority.Secretary of Commerce.5.Maintenance Agency.Department of Commerce, National Institute of Standardsand Technology, Computer Systems Laboratory.6.Cross Index.a.ICAM Architecture Part II-Volume IV - Function Modeling Manual (IDEF0),AFWAL-TR-81-4023, Materials Laboratory, Air Force Wright Aeronautical Laboratories, AirForce Systems Command, Wright-Patterson Air Force Base, Ohio 45433, June 1981.7.Related Documents.a.Federal Information Resources Management Regulations Subpart 201.20.303,Standards, and Subpart 201.39.1002, Federal Standards.b.Integrated Information Support System (IISS), Volume V - Common Data ModelSubsystem, Part 4 - Information Modeling Manual - IDEF1 Extended, December 1985.c.ICAM Architecture Part II, Volume V - Information Modeling Manual (IDEF1),AFWAL-TR-81-4023, Materials Laboratory, Air Force Wright Aeronautical Laboratories, AirForce Systems Command, Wright-Patterson Air Force Base, Ohio 45433, June 1981.d.ICAM Configuration Management, Volume II - ICAM Documentation Standardsfor Systems Development Methodology (SDM), AFWAL-TR-82-4157, Air Force SystemsCommand, Wright-Patterson Air Force Base, Ohio 45433, October 1983.8.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 thoseb.To provide a modeling technique which is independent of Computer-Aided SoftwareEngineering (CASE) methods or tools, but which can be used in conjunction with thosec.To provide a modeling technique that has the following characteristics:-Generic (for analysis of systems of varying 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 ororganizational implementations);-Flexible (to support several phases of the lifecycle of a project).9.Applicability.The use of this standard is strongly recommended for projects that:a.Require a modeling technique for the analysis, development, re-engineering,integration, or acquisition of information systems;b.Incorporate a systems or enterprise modeling technique into a business process analysisor software engineering methodology.The specifications of this standard are applicable when system or enterprise modelingtechniques are applied to the following:a.Projects requiring IDEF0 as the modeling technique;b.Development of automated software tools implementing the IDEF0 modelingThe specifications of this standard are not applicable to those projects requiring afunction modeling technique other than IDEF0.Nonstandard features of the IDEF0 technique should be used only when the neededoperation or function cannot reasonably be implemented with the standard features alone.Although nonstandard features can be very useful, it should be recognized that the use of these orany other nonstandard elements may make the integration of models more difficult and costly.10.Specifications.This standard adopts the Integration Definition for FunctionModeling (IDEF0) as a Federal Information Processing Standard (FIPS).11.Implementation.The implementation of this standard involves two areas of implementations and interpretation of the standard.11.1 Acquisition of IDEF0 Implementations.This publication (FIPS 183) iseffective June 30, 1994.

For Federal acquisitions after this date, projects utilizing the IDEF0function modeling technique, or software implementing the IDEF0 modeling technique, shouldconform to FIPS 183.

Conformance to this standard should be considered whether the project orsoftware utilizing the IDEF0 modeling technique is acquired as part of an ADP systemprocurement, acquired by separate procurement, used under an ADP leasing arrangement, orspecified for use in contracts for programming services.A transition period provides time for industry to develop products conforming to thisstandard.

The transition period begins on the effective date and continues for one (1) yearthereafter
