Symbols used for IDEF3 process description schematics

This IDEF3 symbols example was redesigned from the Wikimedia Commons file: 3-01a Symbols Used for IDEF3 Process Description Schematics.jpg. [commons.wikimedia.org/wiki/File:3-01a_Symbols_Used_for_IDEF3_Process_Description_Schematics.jpg] "Process schematics tend to be the most familiar and broadly used component of the IDEF3 method. These schematics provide a visualization mechanism for process-centered descriptions of a scenario. The graphical elements that comprise process schematics include Unit of Behavior (UOB) boxes, precedence links, junctions, referents, and notes. Referents and notes are constructs that are common across process and object schematics. Each of the graphical elements used for developing process schematics is presented below, together with discussions of how to formulate more complex statements using those graphical elements. The discussion begins with the most fundamental of these building blocks: the UOB."
