Title: General Workflow of Use-Case Driven Development


1
General Workflow of Use-Case Driven Development
2
Use-Case Overview
  • Objectives of requirements capture
  • Identify true requirements
  • Suitable representation for users, customers,
    developers
  • Why use-case?
  • Systematic and intuitive means of capturing
    functional requirements
  • Drive the whole development process
  • Definition of use case
  • Specification of a sequence of actions, including
    variants, that the system can perform and that
    yields an observable result of value to a
    particular type of users (actor)

3
Capturing Use Cases
  • Use case model represents the functional
    requirements
  • From users perspective (fig. 3.3)
  • Focus on interactions of the system with
    environment (actors)
  • Use cases also used as placeholders for
    nonfunctional requirements

Example
5
Creating Analysis Model From Use Cases
  • Analysis model constructed incrementally as more
    use cases analyzed
  • Select use cases to be realized in analysis model
  • Build system as a structure of classifiers
    (analysis classes) and relationship between them
  • Describe collaborations that realize use cases
  • Pick next set of uses cases for the next iteration
