Activity action (system) (UPDM - DoDAF aliases)
Creation
To create an Activity Action (System):
• From an Activity (System): right-click the Activity (System), point to New, point to DoDAF, and then click Activity Action (System). From the Select Type dialog, create or select the Activity (System) that is invoked by the Activity Action (System).
• From an SV-4 Systems Functionality Hierarchy: click the Activity Action (System) button, click the calling Activity (System), and then click the invoked Activity (System).
◦ Click the Activity Action (System) button, and then click in free space or within a containing element on the diagram. From the Select Type dialog, create or select the Activity (System) that is invoked by the Activity Action (System).
◦ From an appropriate Modeler pane, locate the Activity (System) element that is invoked by the Activity Action (System), and then drag that Activity (System) to free space or within a containing element on the diagram.
On the Items tab of an Activity Action (System) element's property pages, you can view and navigate to the Activity (System) that is invoked by the Activity Action (System) through the Linked Item association.
Input Pins and Output Pins
An Activity Action (System) can own Input Pin (System) and Output Pin (System) elements.
On creation of an Activity Action (System), Modeler creates an Input Pin (System) or Output Pin (System) to represent each Parameter (System) of the Activity (System) that is invoked by the Activity Action (System).
Note that after creating an Activity Action (System), Input Pin (System) and Output Pin (System) elements are not automatically created for new Parameter (System) elements that are created on the associated Activity (System).
Appearance
When shown on an SV-4 Systems Functionality Hierarchy, an Activity Action (System) appears as follows:
When shown on an SV-4 Systems Functionality Description, an Activity Action (System) appears as follows:
Relationships
There are no relationships that are of significant importance to an Activity Action (System).
• Activity Performed by Performer relationships can be created by adding an Activity Action (System) to an Activity Partition (System).
The following sections provide information about how an Activity Action (System) is used in the model.
