- The above structure contains three structure elements, each of which have both one product characteristic
(
) and one process characteristic (
) assigned to them. The characteristics of each structure
element are linked to each other within a function net and can be recognized with the hot-click icons 
and 
.
- The nets show how the characteristics are linked to each other as follows:
- This Quality Rule will find any characteristics, for which no inspection equipment has been assigned. Inspection equipment can be assigned to product- and process characteristics in the Control Plan Editor. The following image shows the control plan for this example.
- The way this control plan example looks is down to two reasons; one: while the product- and process characteristics are linked the way they are, and two: the following setting is active: Document settings | Control Plan | General settings for control plan | Display of process characteristics “is based on characteristic/function net”.

In this example, the following characteristics will be found: product characteristics PrdC1 and PrdC2 as well as process characteristic PrcC3, as these do not have inspection equipment assigned.
