12. Use-Cases A description of system behavior, in terms of sequences of actions. A use case should yield an observable result of value to an actor. A use case contains all flows of events related to producing the "observable result of value", including alternate and exception flows. More formally, a use case defines a set of use-case instances or scenarios.actoruse-case instances scenarios The specification of a sequence of actions, including variants, that a system (or other entity) can perform, interacting with actors of the system.actors

13. Use-Cases Business Use-Case A sequence of actions performed by a business that yields an observable result of value to a particular business actor.
