IDEF0 diagram - Inter-box connections

This IDEF0 diagram example was redesigned from the Wikimedia Commons file: 12 Connections Between Boxes.svg. [commons.wikimedia.org/wiki/File:12_Connections_Between_Boxes.svg] "Graphical notation. IDEF0 is a model that consists of a hierarchical series of diagrams, text, and glossary cross referenced to each other. The two primary modeling components are: - functions (represented on a diagram by boxes), and - data and objects that interrelate those functions (represented by arrows). .... the position at which the arrow attaches to a box conveys the specific role of the interface. The controls enter the top of the box. The inputs, the data or objects acted upon by the operation, enter the box from the left. The outputs of the operation leave the right-hand side of the box. Mechanism arrows that provide supporting means for performing the function join (point up to) the bottom of the box." [IDEF0. Wikipedia] The example "IDEF0 diagram - Inter-box connections" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "IDEF Business Process Diagrams" from the area "Business Processes" of ConceptDraw Solution Park.
