Study Notes
Identifying Use Cases
- Use cases are the functions identified, usually in response to a user request
- Two techniques for identifying use cases: user goal technique and event decomposition technique
User Goal Technique
- Identify all potential categories of users of the system
- Interview users to describe tasks that the computer can help them with
- Probe further to refine tasks into specific user goals
- Create a list of preliminary use cases organized by type of user
- Review the completed list with each type of user and then with interested stakeholders
Brief Use Case Descriptions
- A one-sentence description showing the main steps in a use case
Use Case Diagrams
- A UML model used to graphically show uses cases and their relationships to actors
- Symbols used: actor, automation boundary, use case, and the <> relationship
- Types of diagrams: draw for each subsystem, for each type of user, for internal actors, and for use cases of interest
Steps to Create a Use Case Diagram
- Identify all stakeholders and users who would benefit by seeing a use case diagram
- Determine what each stakeholder or user needs to review in a use case diagram
- Select the use cases and actors to show and draw the use case diagram
Explore the different software packages used for drawing use case diagrams and learn how to review use cases with stakeholders and users. This quiz covers techniques for identifying use cases and modeling functional requirements in systems analysis.
