Building Process Hierarchies

You can add processes, and move and hide them in a process hierarchy diagram.

You can create processes with the Process tool from the diagram Toolbox:

To create a ...	Click...
Root process	Any empty space in the diagram window: Note: You can also create and decompose processes in the Browser. To create a root process, right-click the model node in the Browser, and select New > Process. To create sub-processes, right-click the process and select Decompose Object.
Sub-process	A root process symbol or the bottom part of any other process:
Sibling process	The left or right part of any process symbol, except the root process:

You can select and move processes relative to each other, drag and drop them into free space in the diagram. To change your hierarchy, drag and drop a process onto another process to make it a sub-process of that process. All the hierarchy beneath the moved process is moved with it.

To evenly space the sub-processes beneath a process in harmonious lines, right-click the process and select Arrange Symbols. Alternately, select Symbol > Auto-Layout.

By default, a process hierarchy displays from top-to-bottom. To display it from left-to-right, select Tools > Display Preferences > General, and select Horizontal in the Orientation group box.

To hide a process and its children in the hierarchy without deleting it in the model, right-click it and select Edit > Hide Symbols. To display any hidden sub-processes underneath a process, right-click it and select Complete or Complete All.
