Description

The SV-1 addresses the internal composition and interaction of systems.

Implementation

SV-1 can be represented using:

  • A SV-1 diagram which is based on the UML Class diagram.
  • A SV-1 diagram which is based on the UML Composite Structure diagram.
  • A UML Class diagram.
  • A UML Composite Structure diagram.
  • A SysML Block Definition diagram.
  • A SysML Internal Block diagram.

SV-1 Systems Interface Internal Description

An SV-1 can optionally be adorned with performers originally specified in an OV-2. In this way, traceability can be established from the logical OV structure to the physical SV structure.

An interaction, as depicted in the SV-1, is an indicator that information passes from one performer to another. In the case of systems, this can be expanded into further detail in an SV-2. Resource flows are summarized in a Systems-Systems Matrix (SV-3).

The system Functions performed by the Nodes are specified in an SV-4 System Functionality Description, but may optionally be overlaid in the SV-1.

An Operational View (OV) suite may specify a set of requirements – either as a specific operational plan, or a scenario for procurement. As OV-2 and OV-5 specify the logical structure and behavior, SV-1 and SV-4 specify the physical structure and behavior (to the level of detail required by the architectural stakeholders).
