Draw a use-case diagram for the following scenario: You are at a restaurant and you need a ride home. You heard about Unter the on-demand car services company. You down load the mobile app, which supports multiple operating system versions, onto your smart phone and set up an account including credit card information. Once the app is setup, you enter your pickup location and your destination address. When a nearby Unter driver accepts your request, the app displays an estimated arrival time. The driver arrives and takes you home. When you at your home, the fare is automatically and securely billed to your credit card on file with Unter. Before leaving the car, you provide feedback on the driver’s performance via the Unter app. Once Unter has its commission, the remaining fare is deposited automatically and securely into the driver’s account. Your trip has ended.
