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:
“A woman’s whole life is a history of the affections. The heart is her world: it is there her ambition strives for empire; it is there her avarice seeks for hidden treasures. She sends forth her sympathies on adventure; she embarks her whole soul on the traffic of affection; and if shipwrecked, her case is hopeless—for it is a bankruptcy of the heart.”
—Washington Irving (1783–1859)
