This diagram shows an Integrated Definition (IDEF) Function Model Context (Node -0) of the Customer Focused Enterprise model at enclosure 1. It is the foundation (or top level) of the IDEF0 model.
To complete the Function Model for the enterprise, the modelers must have some detailed information about the enterprise. Examples of such detailed information are above, below, and to the left of the Activity block labeled "FORM A CONTINUOUS QUALITY IMPROVEMENT ORGANIZATION".
The information to the right of the Activity block relates to what the enterprise seeks to achieve, their desired goal or outcome.
With this information, the modelers can begin to look at how to map their existing day-to-day enterprise activities to this model. The result is an enterprise-specific Customer Focused Activity Model.
A useful viewpoint to take in performing improvements is to look at the enterprise relations to its larger environment. One way to do this is to track all enterprise inputs (left) and controls (above) to their most fundamental source. With this perspective, identify those environmental elements that constrain (top, left, below) or are effected-by (right) the enterprise and consider them in the modeling efforts.
