Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Represent IDEF0 A-0 as a single block with labeled signals
02
Use block diagram to approximate IDEF0 notation
03Include all four IDEF0 arrow types
input, output, control, mechanism
When modeling the top-level context of any system or process where you need to show data, control, and resource flows without the complexity of full IDEF0 notation.
