IDEF0 Diagrams Software - Create IDEF0 diagrams and business diagrams rapidly with rich examples and templates. Provide some IDEF0 knowledge.
IDEF is based on the Structured Analysis and Design Technique (SADT), a
graphical approach to system description, introduced by Douglas T. Ross in
the early 1970s. Since then, system analysts at Softech, Inc. have refined
and used SADT in a wide variety of problems. In 1981, the U.S. Air Force
Program for Integrated Computer-Aided Manufacturing (ICAM) standardized and
made public a subset of SADT, called IDEF.
IDEF0 diagram was originally used to apply structured methods to better understand
how to improve manufacturing productivity. IDEF0 was initially created at
Northrop Corporation in 1966, and first available commercially by SofTek in
1972. An IDEF0 activity diagram contains
one level of decomposition of a process. Boxes within a diagram show the subprocesses of the parent process named by the diagram. Arrows between the
boxes show the flow of products between processes.

rooted at a chosen node, and used to represent a full IDEF0 decomposition in
a single diagram.
The Benefits of Using IDEF0 to
Model Business Processes
- Understanding - modeling helps discover the
nature of the business being modeled; that is, what is being done in the
- Communication - once understanding has been
reached, the nature of the business processes can be documented and
these documents easily communicated.
- Enlightenment - modeling helps to uncover
anomalies, redundancies deficiencies and inefficiencies in the existing
(as-is) business process.
- Improvement - a model allows you to select
deficient areas of the business and its processes and improve them.
- Redesign - a model provides a tangible basis
for redesigning the process, performing simulations of the redesigned
(to-be) business process as defined by the strategy. This means that
strategies can be tested before implementation takes place.
The IDEF0 Modeling
An IDEF0 model represents the
activities of the business from the point of view of the business, how those
business activities interrelate, resources used to conduct each activity,
and the result or output of each activity. The model consists of graphics
and associated text supporting the graphics.
The IDEF0 modeling technique
consists of a graphic language and a modeling process that can be used to
develop a rich process description. It is an intuitive way to define,
analyze and document the business as a whole and the processes of the
The IDEF0 notation was standardized in
1993 by the National Institute of Standards and Technology of the United
States Department of Commerce and is a public domain methodology. IDEF0 is a
subset of the complete IDEF0 system modeling methodology which includes
process and information modeling.
There are a number of business
process and information modeling notations around. Most of these are part of
proprietary methodologies developed by consulting firms.
IDEF0, being in the public domain,
is dismantling the Tower of Babel to the point where a model's main
purpose and communication can now be achieved.
The modeling of the entire business
and its processes is especially difficult because, even in small- and
medium-sized businesses, business processes are complex and referred to as
being of medium complexity. The IDEF0 method facilitates the modeling of the
business as a complex system so it can be understood and improved.
Business Process Modeling Using IDEF
IDEF (Integrated Definition) diagrams were
introduced in 1981 as part of the Integrated Computer-Aided Manufacturing
(ICAM) project. There are numerous IDEF methods, but two of them serve as
the basis for business process models: the IDEF0 method that focuses on
activity modeling and the IDEF3 method that accomplishes process description
and can be used to rapidly generate discrete-event simulation model
specifications (Mayer et al, 1998). The IDEF0 method is designed to model
the decisions, actions, and activities of an organization or other system
and is targeted to communicating and analyzing the functional perspective of
a system (Mayer et al 1998).
Perhaps the main strength of IDEF0 is its simplicity, as it uses only one
notational construct, called the ICOM (Input-Control-Output-echanism). IDEF3
describes processes as ordered sequences of events or activities. As such,
IDEF3 is a scenario-driven process flow modeling technique, based on the
direct capture of precedence and causality relations between situations and
events (Mayer et al 1998). The goal of an IDEF3 model is to provide a
structured method for expressing the domain experts' knowledge about how a
particular system or organization works (as opposed to
IDEF0, which is mainly concerned with what activities the organization
performs). Similar to IDEF0, the main strength of IDEF3 is the simplicity of
its notation, which relies on only one basic construct, called the UOB (Unit
