on the driver’s desktop. In addition, there should be a video chat facility to allow the programmers to
communicate. The system should allow the programmers to easily swap roles and record rationale in
the form of video chats. In addition, the driver should be able to issue the system to backup old work.

.
Use the information in the next scenario to answer question 4.1
The shipping department receives all shipments on outstanding purchase orders. When the clerk in the
shipping department receives a shipment, he or she finds the outstanding purchase order for those
items. The clerk then sends multiple copies of the shipment packing slip. One copy goes to Purchasing,
and the department updates its records to indicate that the purchase order has been fulfilled. Another
copy goes to Accounting so a payment can be made. A third copy goes to the requesting in-house
customer so he or she can receive the shipment. After payment is made, the accounting department
sends a notification to Purchasing. After the customer receives and accepts the goods, he or she sends
notification to Purchasing. When Purchasing receives these other verifications, it closes the purchase
order as fulfilled and paid.

Question 5 [24]
Consider the case study that follows:
When a contractor buys materials at Quality Building Supply, he takes it to the contractor checkout desk. The clerk
enters the contractor’s name into a point-of-sale system (the system). The system displays the contractor record,
including his current credit standing. The clerk then opens up a new sales record for the contractor. Next, the clerk
scans in the number of the item to be purchased into the system. The system finds the price and product name,
then displays these on the screen and adds the item to the sales record. In turn, the clerk enters the quantity of
the item. When all items are scanned, the clerk ends the sale. The system calculates the total and checks it against
the contractor’s credit limit. If the limit is not reached, the system updates the contractor’s account by subtracting
the amount of the sale from the credit available. If the credit limit is reached, the clerk is alerted to ask for a cash
payment. If the contractor does not wish to pay in cash, the clerk cancels the sale. Successfully closed sales are
finalized so that the system prints a receipt.
5.1 To describe the above scenario, provide a fully developed use case description. (24)
