How to Create an IDEF0 Diagram

IDEF0 is a modeling tool used to model the decisions, actions, and activities of an organization or system. Diagrams are a major component of an IDEF0 model. ConceptDraw DIAGRAM allows you to create professional IDEF0 Diagrams using IDFE0 notation supplied by the IDEF Business Process Diagrams solution. This solution is a paid add-on to ConceptDraw DIAGRAM, that provides individuals with extensive new libraries and objects to assist in IDEF process definition at an economical price.

1. Open a new ConceptDraw DIAGRAM document and select the IDEF0 diagrams library.
2. An IDEF model is made up of several diagrams. Each diagram describes in more detail a box from a more general diagram. It can be started from the Diagram Form element.
