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:
“A new talker will often call her caregiver “mommy,” which makes parents worry that the child is confused about who is who. She isn’t. This is a case of limited vocabulary rather than mixed-up identities. When a child has only one word for the female person who takes care of her, calling both of them “mommy” is understandable.”
—Amy Laura Dombro (20th century)
