Artifact: Subsystem Model
This work product is a model of the subsystem from an external point of view, or a part of the system, that defines the main elements, their structure, relationships and behavior. The work product is typically maintained in a modeling tool, is handed off - either by-value or by-reference - to the subsystem team and is then elaborated by that team.

Description
Main Description

This is a package or submodel within the system engineering model and generally consists of a set of diagrams and semantic elements (e.g. requirements, blocks, logical interfaces, constraints, states, transitions, flows, traceability links, and data elements). These sets of elements together specify the requirements for the subsystem.
