I need to make a use case diagram for a use case document that I wrote. I am having a little trouble knowing what to do and I was wondering if someone could help me. Here is the scenario and preconditions of my use case:

Use Case: User Monitors Order Status During Delivery

Preconditions: (If any): This use case has the following preconditions:

  • User must be logged into their account
  • User must have successfully completed a purchase
  • User must have an active order
  • User must have access to their order number
  • Users must have a valid shipping address
  • Users must have access to a GPS mapping application (Google Maps, Apple Maps, etc.)

Trigger: User wants to track the delivery status of their recent purchase

Scenario: List the steps

  1. The user has successfully completed an online order.
  2. The user receives an email or text message containing the order number.
  3. The user clicks the link containing the order number and selects the option to track the current order.
  4. The user enters their order number.
  5. The system opens the users GPS mapping application in order to display the current location of the users order
  6. The mapping application displays a live feed of the units location as well as the route that is being taken to reach the designated destination.
  7. The system displays the current date and time as well as the expected delivery date and time of the users order.
  8. The system sends notifications via text and email when something involving the order shipment has changed. (Technical issues with the unit, weather delays, order cancellation, etc.)
  9. The user is notified when the order is delivered, and a time stamped photo is taken and sent to the user for verification.
  10. The user must verify that the delivery location is correct.
  11. The system alerts the user that the order has been fulfilled and the unit is recalled once delivery verification has been received.
  12. The system is updated and includes the completion details of the order for that specific user. This includes name, address, order delivery shipment date, order delivery date, order delivery accuracy status.
