2. Objectives Define the elements of the use case model. – Use cases – Actors – Relationships – Use case diagrams Add diagrams to the Use Case View. – Link documentation – Link flow of events

3. Where Are We?

4. Requirements Workflow Analysis and Design Workflow Where Are We?

5. Key Concepts Use Case Model

6. Use Case Diagrams – Actors – Use cases – Relationships Key Concepts

7. Lab Objectives – Name the model and set up stereotype icons. – Create a use case model. Actors Use cases Relationships Supplemental documentation Flow of events

8. Add Use Case Diagram to Model Actors added to diagram In Rose, select from toolbar and drag into model window. Label.

9. Add Use Case Diagram to Model Use Cases added to diagram Use same technique: Select and drag; Label

10. Add Use Case Diagram to Model Unidirectional associations added to diagram

11. Add Use Case Diagram to Model Main use case diagram Actor Associations Use Cases Shows that ‘this’ actor has a relationship to ‘these’ Use Cases

12. Add Flow of Events Flow of events added to use case model Expanded Use Cases: Shows ‘actors’ associated with the Use Cases

13. Add Supplemental Documentation Supplemental documents added to use case model

14. Preferred Practices Create in Use Case View. Use Packages to organize the model. Represent each use case on at least one use case diagram. Show interactions between actors and use cases. Show relationships between use cases, if applicable.
