CORE DEFINITION

Integration Definition (IDEF) function modeling technique: ICOM elements: - I (Input): Input - data or objects to be transformed - C (Control): Control - conditions or rules constraining the execution of an activity - O (Output): Output - results produced by the activity - M (Mechanism): Mechanism - resources required to perform the activity. Diagram rules: - Functions are represented by rectangles - Inputs enter from the left - Outputs exit from the right - Controls enter from the top - Mechanisms enter from the bottom. Scaffold role: Standardized modeling, clear expression. IDEF0 provides a strict

Anchor fast decisions

Function modeling technique of the Integration Definition method. It strictly describes activities using ICOM elements: I (Input), C (Control), O (Output), M (Mechanism). Diagram rules: function rectangles, inputs enter from the left, outputs exit from the right, controls from the top, mechanisms from the bottom. The mechanism is **standardized functional decomposition**, making the activities and constraints of complex systems clear and communicable.
