IDEF4

It specifies design objects with sufficient detail to enable source code generation.

[1] This method is part of the IDEF family of modeling languages in the field of systems and software engineering.

[2] The IDEF4 method multi-dimensional approach to object-oriented software system design consists of the following items:[1] The development of IDEF4 came from the recognition that the modularity, maintainability, and code reusability that results from the object-oriented programming paradigm can be realized in traditional data processing applications.

Since effective usage of the object-oriented paradigm requires a different thought process than used with conventional procedural or database languages, standard methodologies such as structure charts, data flow diagrams, and traditional data design models (hierarchical, relational, and network) are not sufficient.

IDEF4 seeks to provide the necessary facilities to support the object-oriented design decision making process.

The edges of the box show the progression of the design from start to finish elaborating each of these dimensions.

This develops the design context, ensures connectivity to legacy systems, and identifies the applications that must be built to satisfy the requirements.

[1] IDEF4 is an iterative procedure involving partitioning, classification/specification, assembly, simulation, and rearranging activities (see figure).

While the models are developed, it is important to simulate use scenarios or cases[5] between objects to uncover design flaws.

[6] However, IDEF4 practitioners should be aware of how objects are identified, as the design process may reveal deficiencies in the Object-Oriented Analysis.
