System context (UPDM - DoDAF aliases)
Creation
To create a System Context:
From an Architectural Description or Service Description: right-click the Architectural Description or Service Description, point to New, point to DoDAF, point to System, and then click System Context.
From a System Context: right-click the System Context, point to New, point to DoDAF, and then click System Context.
From an SV-1 Systems Interface Definition, SV-4 Systems Functionality Hierarchy, SV-5 Function to Operational Activity/Service Function Definition, or SV-9 Systems Technology and Skills Forecast Definition: click the System Context toolbar button, and then click in free space on the diagram.
Appearance
When shown on an SV-1 Systems Interface Definition, SV-4 Systems Functionality Hierarchy, SV-5 Function to Operational Activity/Service Function Definition or SV-9 Systems Technology and Skills Forecast Definition, a System Context appears as follows:
When shown on an SV-1 Systems Interaction Specification or SV-2 Systems Resource Flow Description, a System Context appears as follows:
Relationships
The following relationships are of importance to a System Context:
UML Generalizations define System Context inheritance ( SV-1 Systems Interface Definition).
Forecast relationships link a System Context to forecasted future System Context elements.
Implements relationships link a System Context to the Performer (Operational) elements it implements.
Activity Performed by Performer relationships to link a System Context to the Activity (System) elements that can be performed by the System Context.
Used as a type for System Port and Resource Role elements.
Used as a conveyed classifier for Operational Exchange elements.
The following sections provide information about how a System Context is used in the model.
Create a System Context from
