What is the IDEF-0 modeling technique and how can it be used to document EA components at the Business Level of the EA3 framework?
The Integration Definition for Function, or IDEF technique. Developed in the mid-1970’s for modeling complex military projects, IDEF-0 uses Inputs, Outputs, Controls and Mechanisms (ICOM) to show the parts of an activity within an enterprise. IDEF-0 activity modeling is suitable for business process documentation in that it provides both high level context views, and more detailed views of each step in the activity in a format that can be further decomposed and interrelated with other processes to show linkages. IDEF-0 modeling is useful in showing linkages between steps in a process as well as internal external influences, but does not indicate a particular time sequence for the overall set of activities.
