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:
“The doctors are all agreed that I am suffering for want of society. Was never a case like it. First, I did not know that I was suffering at all. Secondly, as an Irishman might say, I had thought it was indigestion of the society I got.”
—Henry David Thoreau (1817–1862)
