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:
“When a thing is said to be not worth refuting you may be sure that either it is flagrantly stupid—in which case all comment is superfluous—or it is something formidable, the very crux of the problem.”
—Miguel de Unamuno (1864–1936)
