- The 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 either no control method or no reaction plan has been assigned. Control methods and reaction plans can be allocated 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”.
Search result: 
In this example, the following characteristics will be found: product characteristic PrdC3 as well as the process characteristics PrcC1, PrcC2 and PrcC3, which all have either control methods or reaction plans missing or both.
The product characteristic PrdC2 is not found, as it has the control method from PrdC1 and the reaction plan from PrdC3 assigned to it.
