Structured Analysis - IDEF0

This note introduces the IDEF0 modelling language (semantics and syntax), and associated rules and techniques, for developing structured graphical representations of a system or enterprise. Use of this standard for IDEF0 permits the construction of models comprising system functions (activities, actions, processes, operations), functional relationships, and data (information or objects) that support systems integration.

An IDEF0 model is domain specific in the sense that purpose, viewpoint and context must be identified in the model. The IDEF0 modelling language is recommended for projects that require a modelling technique for the analysis, development, re-engineering, integration, or acquisition of information systems; and incorporate a systems or enterprise modelling technique into a business process analysis or software engineering methodology.This note is a summary of the Standard for Integration Definition for Function Modelling (IDEF0).
