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:
“Of all my prosecutors ... not one is my peer, but each and all are my political sovereigns; and had your honor submitted my case to the jury, as was clearly your duty, then I should have had just cause of protest, for not one of those men was my peer; but, native or foreign born, white or black, rich or poor, educated or ignorant, sober or drunk, each and every man of them was my political superior; hence, in no sense, my peer.”
—Susan B. Anthony (1820–1906)
