Terminology

Trigger: The initiator of a Use Case
Use Case: A methodology used in system analysis to identify, classify and organise system requirements
Use Case Scenario: Represents the actions that are required to to enable, or abandon a goal
User Story: A description of interactions between a system and one or more actors

The Composition of a Use Case
Like much of System Analysis, we can think of the use of the system from the perspective of the…
