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
