Main Description



 



Check Items




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
