Modeling services on SV-1 Systems Interface diagrams
You can model Services on the SV-1 Systems Interface diagram. You can visually specify the systems that perform the services by drawing the services in system entity symbols on the diagram. You can group services into service family symbols on the diagram, and you can also show how services relate to one another by drawing a service interface line between the services.
Prerequisite
Open an SV-1 diagram containing system entities that you modeled previously.
Procedure
1 Draw service families in system entities on the SV-1 diagram.
The service family is a new definition type that provides a categorization of services. A service can belong to one or more service families. The service family is represented as a rounded rectangle on the SV-1 diagram.
2 Draw services in service families, or directly in the system entity, on the SV-1 diagram.
These services should belong to the same service family definitions as presented on the SV-4b Service Hierarchy diagram.
3 For services that have relationships to one another, draw a service interface line between the services.
4 Save the SV-1 diagram.
Result
When you save the SV-1 diagram, the software detects the presence of service interface lines between services and updates the Client Services and Supplier Services properties of each service definition. The “to” end of the line denotes the client; for example, drawing a service interface line from Service A to Service B makes Service A the supplier service, and Service B the client service. These relationships are also represented in the SV-3 Services-to-Services matrix.
Example
The following image shows an example of an SV-1 diagram containing a system entity, Mission Systems Node, which contains a service family, UAV Navigation. This service family contains two services, one of which has a service interface relationship to a service in another system entity.
