In the Chapter 6, you considered the issue relevant to the speciation of the hardware equipment and networking requirements. The case description in the Chapter 6 also reviewed the three primary types of users for the system and many of their respective system-supported activities.

In Chapter 5, you developed activity diagrams system sequence diagram for two use cases: Request a package pickup and pick up a package. In Chapter 4, you developed a domain model class diagram for the system.

1) For each of two use cases, develop a first-cut DCD and a set of CRC cards. The design class diagram should elaborate the attributes and show navigation visibility. You many also need to add more classes from your solution in Chapter 4. It isnt uncommon for developers to enhance early models as they began to understand system requirement better. The CRC cards should include classes for the controller class and any classes for screens you identified in Chapter 7.

2) Update the DCD with method names for the CRC cards. For this solution, do not try to determine entire method signatures, just the names.
