Use Case

In UML, a Use Case is a Model Element that specifies a set of Actions performed by a subject to yield an observable result of value to an Actor or other stakeholder.

SimpleModeling treats a Use Case as an intent axis composed of an Actor, Goal, Scenarios, and Outcomes. A natural-language Use Case Scenario is a kind of Literate Model. The Scenario is concretized as an Execution Example Model such as an Interaction, and the reviewed mapping guides the design of executable Objects, Services, Operations, Events, StateMachines, Constraints, and related elements.
