This task creates a model to hold both interfaces elements (interfaces, operations, data types) and internal semantic elements shared by multiple subsystems.
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.
