Discussion Questions
As an analyst you will define use cases at two levels: 1) an overview level and 2) a detailed level. The event table and use case diagrams provide an overview of all use cases for a system. The integrated nature of the UML models requires that the models integrate together to give a total description of the business requirements. Discuss the following questions:
• What does it mean to have integrated requirements models?
o How should they be used?
• Each of the UML models relates to the other models.
o How can cross checking between models ensure that the requirements are accurate and correct?
o Illustrate your answer with an example.
• What are the dangers of not cross checking between the models?
• What is the principal distinction (purpose) between a use case activity diagram and a system sequence diagram?
o Explain when you might use one instead of the other.
