White Paper: One Model

One Model, Many Interests, Many Views

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
