Building the Use Case Diagram
Session Checklist
✔ Understanding the steps used to build a Use Case diagram
✔ Building the Use Case diagram for the case study
Session 5 introduced the notation for the Use Case diagram. In this session, you find
out how to build a Use Case diagram by concentrating on the case study.
Building the Use Case Diagram for the Case Study
The following text makes up the description of the case study. I refer to this as the problem
statement. Use this problem statement as your source for the information needed to build
the Use Case diagram.
You will see the problem statement change from session to session. This is
necessary within the book because I need to tailor the problem so that you
Note will have an opportunity to use as many of the new concepts as possible in
each session.
Receiving: The receiving clerks receive incoming shipments by matching purchase orders
against the stock in the shipment. They inform the Accounts Payable department when the
purchase order items have been received. The clients want the new system to handle the
notification automatically.
Stocking: The products may come from cancelled orders, returned orders, or vendor shipments.
The products are placed in the warehouse in predefined locations. The stock clerk looks
up the correct location for the new products, places the products in that location, and updates
the location inventory with the product quantity.
