In software and systems engineering, a use case (pronounced /juːs/, a case in the use of a system) is a list of steps, typically defining interactions between a role (known in UML as an "actor") and a system, to achieve a goal. The actor can be a human or an external system.
In systems engineering, use cases are used at a higher level than within software engineering, often representing missions or stakeholder goals. The detailed requirements may then be captured in SysML or as contractual statements.

Famous quotes containing the word case:
“The circumstances with which every thing in this world is begirt, give every thing in this world its size and shape;—and by tightening it, or relaxing it, this way or that, make the thing to be, what it is—great—little—good—bad—indifferent or not indifferent, just as the case happens.”
—Laurence Sterne (1713–1768)
