Use Case Descriptions • actors - something with a behavior or role, e.g., a person, another system, organization. • scenario - a specific sequence of actions and interactions between actors and the system, a.k.a. a use case instance • use case - a collection of related success and failure scenarios, describing actors using the system to

A use case diagram is used to represent the dynamic behavior of a system. It encapsulates the system's functionality by incorporating use cases, actors, and their relationships. It models the tasks, services, and functions required by a system/subsystem of an application.

Use Case Diagram Examples. The figure below shows an ATM use case diagram example, which is quite a classic example to use in teaching use case diagram.
