"Paper changes are cheap."
Gerald Weinberg

During initial system design it is important to have a robust and business-driven method of capturing and validating functional requirements from the perspective of different classes of users for a planned technical solution. A use case defines a future set of steps or actions that will likely be performed by the user or other stakeholder in the use of an anticipated application.

Use cases are documented in the form of use case diagrams and textual flows of events called use case scenarios. The use case diagrams depict the interaction between the users (actors), processes (use cases) and systems (external interfaces). The use case scenario describes the interaction between the actors, the proposed system, and any external interfaces.

In addition to being used as functional specification documents, use cases can also be used in an Object Oriented Design approach as inputs towards developing:

  • UML class diagrams by:
    • Identifying information needs and possible edits
    • Identifying validation rules to be incorporated in to business objects
    • Identifying business rules that could be supported by stored procedus
  • Interaction diagrams by:
    • Determining necessary system/user interactions
    • Identifying the need for screen mockups
  • UML Activity diagrams by:
    • Providing input for Navigational Maps
