SV-4 Systems functionality description (UPDM - DoDAF aliases)
Creation
To create an SV-4 Systems Functionality Description:
• Right-click the Activity (System) that is to own the SV-4 Systems Functionality Description, point to New, point to DoDAF, and then click SV-4 Systems Functionality Description.
Purpose
In addition to the UML Activity Diagram items that can be created on an SV-4 Systems Functionality Description, on an SV-4 Systems Functionality Description:
• Create Operation Action (System) elements, and on those elements create Input Pin (System) and Output Pin (System) elements.
• Create Operation Action (Service) elements, and on those elements create Input Pin (Service) and Output Pin (Service) elements.
• Create Control Flow (System) and Object Flow (System) links, and on those links create realizing Command, Control and Resource Exchange elements.
• Create Activity Partition (System) elements that represent system resources.
• Create Activity Performed by Performer relationships between system resource and Activity (System) elements by creating Activity Action (System) elements within the Activity Partition (System) elements that represent those system resources.
• Create Activity Structured Node (System) elements.
Diagram Elements
For information about showing compartments on diagram symbols, setting up default view options and adding existing elements to the diagram, see
For information about the creation and appearance of elements that can be shown on all Product diagrams (Representation, Definition, Information, Metadata, Overlap and Same As elements), see.
An SV-4 Systems Functionality Description is based on a UML Activity Diagram. For information about the UML Activity Diagram items that can appear on an SV-4 Systems Functionality Description, see the Modeler Help.
Activity Action (System)
To create an Activity Action (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).
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.
Modeler creates an Input Pin (System) or Output Pin (System) to represent each Parameter (System) of the Activity (System) that is used as the type of the Activity Action (System).
If you create the Activity Action (System) within an Activity Partition (System), Modeler creates an Activity Performed by Performer relationship between the system resource that is represented by the Activity Partition (System) and the Activity (System) that is selected as the type of the Activity Action (System).
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.
To create an Activity Partition (System): click the 
Activity Partition (System) button, and then click in free space or within an Activity Partition (System) on the diagram. From the Select Type dialog, create or select the system resource or Resource Role that is represented by the Activity Partition (System).
When the represented system resource is related to other system resources through Resource Role relationships, you can quickly create and add nested Activity Partition (System) elements to represent those Resource Role elements: right-click the Activity Partition (System), point to Populate, point to Nodes and then click Function Partitions (New & Existing).
You can use Activity Partition (System) and Activity Action (System) elements to create and delete Activity Performed by Performer relationships between system resource and Activity (System) elements:
• When you create the Activity Action (System) within an Activity Partition (System), Modeler creates an Activity Performed by Performer relationship between the system resource that is represented by the Activity Partition (System) and the Activity (System) that is the type of the Activity Action (System)
Dragging an Activity Action (System)
to an Activity Partition (System) creates an Activity Performed by Performer relationship between the system resource that is represented by that Activity Partition (System) and the Activity (System) that is the type of the Activity Action (System).
• Dragging an Activity Action (System)from an Activity Partition (System) deletes the Activity Performed by Performer relationship that exists between the system resource that is represented by the Activity Partition (System) and the Activity (System) that is the type of the Activity Action (System).
Through the View Options you can show the Activity Partition (System) vertically or horizontally.
On the Items tab of an Activity Partition (System) element's property pages, you can view and navigate to the element that is represented by the Activity Partition (System) through the Linked Item association.
An Activity Performed by Performer is shown on the diagram through an Activity Action (System) appearing in an Activity Partition (System). For more information, see the Activity Partition (System) section.
