- The name of each subsystem is unique and descriptive of the
collective responsibilities of the subsystem.
- The subsystem description accurately reflects the collective
responsibilities of the subsystem.
- The subsystem, through its interfaces, presents a single,
logically consistent set of services.
- The subsystem is the responsibility of a single individual or
team.
- The subsystem realizes at least one interface
- The interfaces realized by the subsystem are clearly
identified and the dependencies are correctly documented.
- The subsystem’s dependencies on other model elements is
restricted to interfaces and packages to which the subsystem has a
compilation dependency
- The information needed to effectively use the subsystem is
documented in the subsystem facade.
- Other than the interfaces realized by the subsystem, the
subsystem’s contents are completely encapsulated.
- Each operation on an interface realized by the subsystem is
utilized in some collaboration.
- Each operation on an interface realized by the subsystem is
realized by a model element (or a collaboration of model elements) within
the subsystem.
- Subsystem partitioning done in a logically consistent way across
the entire model
- The contents of the subsystem are fully encapsulated behind
its interfaces
