In the On the Spot system, package pickup and deliv- ery are closely integrated with route schedules.
How- ever, recall the RMO system, where there is a Sales subsystem, an Order fulfillment subsystem, a Cus- tomer account subsystem, and a Marketing subsystem. You could conceive of the On the Spot system as also consisting of four subsystems:
¦ Customer account subsystem (like customer account) ¦ Pickup request subsystem (like sales) ¦ Package delivery subsystem (like order fulfillment) ¦ Routing and scheduling subsystem
Assuming that On the Spot's system developer approached this new system from this point of view and that the developer also decided to use an adaptive, iterative approach:
1. What should be included in a package diagram with dependency relationships?
2. Create that package diagram.
