Select the Shadow Variable tool and click on the sketch below target capacity. A dialog box opens:
| Ø | Either select the variable word of mouth demand from the list, or type the first few letters of word of mouth demand until it becomes highlighted in the list, then press Enter or click on OK. |
| Ø | Select the Arrow tool and click on the Shadow Variable word of mouth demand then click on target capacity. |
The structure of this view is now complete. The structure is causally linked to the first view through the variable word of mouth demand.
NOTE The shadow variable is only inserted for use in causing other things to change. If you tried to connect an arrow from another variable to the shadow variable, the arrow will not connect. If you want a variable from another view to be caused by something in this view, you need to use the Model Variable tool, which adds a variable and all its causes to a view.
