Create a dependency between OBS nodes

IPP&E allows you to indicate the cost estimate for a functional organization based on the cost estimate of another functional organization for the same WBS work package. Do this by creating a dependency between the two functional organizations in the OBS.

(The source page includes a diagram showing dependencies between functional organizations in the OBS — not reproduced here as it is an image.)

In the diagram, the Quality functional organization depends on the Planning organization. Consequently, the cost estimate of the quality work package is a factor in the cost estimate of the planning work package.

Create an OBS dependency as follows:

Procedure

1. Open the OBS element or select it in the OBS hierarchy in which the OBS element is dependent (for example, the Planning OBS), and click Copy.

2. Open the OBS element or select it in the OBS hierarchy in which it depends on others (for example, the Quality OBS), and click Paste from the work area toolbar in the Depend On section of the Related Data tab.

   The system relates the two OBS elements.

3. To add a dependency factor percentage, select the dependent OBS element in the Related Data tab of the depending OBS, choose Edit → Start Edit, edit the value of the factor in the Depend On section, and then click Save.
