Description

To define requirements by writing and revising an Artifact: Use Case. A Use Case defines a sequence of actions initiated by an actor in order to achieve a goal. The sequence of actions is described in terms of interactions between actors and the system, application, or website. The Use Case uses domain (i.e., stakeholder and subject matter expert) terminology. It does not describe user interface details such as menus and buttons; it focuses on functional behavior from a black box perspective.
