Task: Create Shared Model
This task creates a model to hold both interfaces elements (interfaces, operations, data types) and internal semantic elements shared by multiple subsystems.
Disciplines: System Engineering Architecture
Purpose
The purpose of the shared model is to provide a location for interface and semantic elements that are used by multiple subsystems.

      Main Description
      The shared model is used by multiple subsystems to hold information used by them. It typically organized into three primary areas - overall architectural descriptions, interface elements, and internal but common elements.
      Steps
      Determine shared model organization
      Create shared model
      Create shared model organization
      Establish shared model baseline
      Key Considerations
      Elements that fall completely within one subsystem should be represented solely within that subsystem.
