IDEF0 Diagram

Originally specified by National Institute of Standards and Technology (NIST) Standard FIPS-183, the

IDEF0 diagram presents an integrated picture of the inputs, control, outputs, and mechanisms (ICOM)

for a function’s decomposition. The IDEF0 diagram displays a great deal of context information on

the interrelationships of decomposition and implies sequencing, but displays no actual control logic /

structure of the decomposition.

Level of Detail:

High

Audience:

Traditional SEs and process engineers

Content:

Data flow, triggering, and allocation

Use:

Analysis of data flow with diagnostics of inconsistencies across

behavioral decomposition requirements to system threads
