Advantages of use cases and scenarios

  • Places a requirement’s statement “in context”
  • Acquiring requirements by exploring “what if” questions
  • Scoping required system by exploring system actions
  • Validating requirements by exploring alternative courses
  • Provide a basis for system and acceptance testing
  • Reduce system complexity
  • Excellent for communicating/agreeing requirements
  • Encourage inter-disciplinary learning
  • Little training and experience needed to use them
  • Scenarios can evolve over time
