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:
“Massachusetts sat waiting Mr. Loring’s decision.... It was really the trial of Massachusetts. Every moment that she hesitated to set this man free, every moment that she now hesitates to atone for her crime, she is convicted. The commissioner on her case is God; not Edward G. God, but simply God.”
—Henry David Thoreau (1817–1862)
