In order to do most of the Instructional Design activities that VISION supports, you will need to open a Hierarchy Workbench. One way to open a Hierarchy Workbench is to use the Main Menu. From the Main Menu, select Workbench. Then choose the type of Workbench you want. Each type of Workbench opens a different combination of hierarchies.
If the Open... Work Area window appears, highlight a Project Work Area and click the OK button. Note that this selection box does not appear if there is only one work area in the project of the given type (Analysis, Objective or Program). If there is only one, VISION opens it automatically.
When you open the hierarchy, it will look like this:
In this example, the Workbench shows the Analysis Hierarchy for a Work Area called “LightWave Field Service”. All that you can see at this point is the top, or “parent” node of the hierarchy. The 
symbol indicates there are more nodes, or “children” below the parent.
