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:
“Oh, that I knew where I might find him, that I might come even to his dwelling! I would lay my case before him, and fill my mouth with arguments. I would learn what he would answer me, and understand what he would say to me. Would he contend with me in the greatness of his power? No; but he would give heed to me. There an upright person could reason with him, and I should be acquitted forever by my judge.”
—Bible: Hebrew, Job 23:3-7.
Job, of God.
