Description

The Systems Interface Description links together the operational and systems architecture views by depicting the assignments of systems/system functions, and systems nodes (and their associated interfaces) to the operational nodes (and their associated needlines) described in OV-2.  The OV-2 depicts the operational nodes representing organizations, organization types, and/or human roles, while the SV-1 depicts the systems nodes which house operational nodes (e.g., platforms, units, facilities, and locations) and the corresponding systems/system functions, resident at these systems nodes and which support the operational nodes.  Most architecture uses involve the analysis of alternative materiel solutions, and therefore knowledge of the systems, their locations, and their functions is essential to analysis. 

While the SV-1 is highly applicable for most uses, it is usually not applicable for conducting Business Process Re-Engineering/Functional Process Improvement where the intent is to address activities and processes independent of systems.
