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:
“There are a great many of these accusers, and they have been accusing me now for a great many years, and what is more, they approached you at the most impressionable age, when some of you were children or adolescents; and literally won their case by default, because there was no one to defend me.”
—Socrates (469–399 B.C.)
