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 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.
