  13. Form a small group of students. Have each group (or student in the group) choose a division of MRE. Explain the nature of the MRE division to the group.

  14. Draw a use case diagram for the Ecommerce System. Refer to the JAD session linked from the Silver interview. Think about the actors and how they would use the system.

    When looking for actors, does the context level data flow diagram provide some of this information, perhaps some of the external entities?

    When looking at use cases, think about the different ways that the system would be used by the actors. Diagram 0 may provide some assistance in identifying how the system is used.

    Remember that this is what is called a logical view, and to look at what the system should do rather than how the system should accomplish the tasks. Use the following to help produce the diagram:

    Possible actors

    Customer
    Warehouse Operations and Shipping
    Credit Card Company
    Customer Service

    Possible activities

    Add new customer
    Verify existing customer
    Sending order confirmation to customer
    Send shipped order confirmation to customer
    Get credit card information
    Receive customer return information
    Select products for shopping cart
    Looking up customer information in response to an inquiry
    Producing statistical analysis reports
