Question

Bold is chapter 2 info Book name: Systems Analysis and Design in a Changing World 7e

As an employee of a large international courier and shipping service, Bill Wiley met with many companies that shipped and received packages almost every day. He was frequently asked if his company could deliver local packages on the same day. Over several months, he observed that there appeared to be a substantial need for courier services in the city in which he lived. He decided that he would form his own courier delivery company called On the Spot to fill this need.

Bill began by listing his mobile telephone number in the Yellow Pages. He also sent letters to all those companies that had requested same-day courier ser- vice that his prior company had not been able to serve. He hoped that through good service and word-of- mouth advertising that his business would grow. He also began other advertising and marketing activities to promote his services.

At first, Bill received delivery requests on his business mobile phone. However, it was not long before his customers were asking if he had a Web site where they could place orders for shipments. He knew that if he could get a Web presence that he could increase his exposure and help his business grow.

After he had been in business only a few short months, Bill discovered he needed to have additional help. He hired another person to help with the delivery and pickup of packages. It was good to see the business grow, but another person added to the complexity of coordinating pickups and deliveries. With the addition of a new person, he could no longer “warehouse” the packages out of his delivery van. He now needed a central warehouse where he could organize and distribute packages for delivery. He thought that if his business grew enough to add one more delivery person that he would also need someone at the warehouse to coordinate the arrival and distribution of all the packages

When Bill got an order, only on his phone at first, he recorded when he received the call and when the shipment would be ready for pickup. Sometimes, customers wanted immediate pickup; sometimes, they were calling to schedule a later time in the day for pickup. Once he arrived at the pickup location, Bill collected the packages. It was not uncommon for the customer to have several packages for delivery. In addition to the name and address of the delivery location, he also recorded the time of pickup. He noted the desired delivery time, the location of the delivery, and the weight of the package to determine the courier cost. When he picked up the package, he
printed out a label with his portable printer that he kept in the delivery van. At first, Bill required customers to pay at the time of pickup, but he soon discovered that there were some regular customers who preferred to receive a monthly bill for all their shipments. He wanted to be able to accommodate those customers. Bills were due and pay- able upon receipt.To help keep track of all the packages, Bill decided that he needed to scan each package as it was sorted in the warehouse. This would enable him to keep good control of his packages and avoid loss or delays.The delivery of a package was fairly simple. Upon delivery, he would record information about when the delivery was made and who received it. Because some of the packages were valuable, it was necessary in those instances to have someone sign for the package upon delivery.

Answer questions 1-3 including developing the use case diagram in either Visual Paradigm or Visio

1. From this description as well as the information from Chapter 2, identify all the actors who will be using the system.

2. Using the actors who you identified in question 1, develop a list of use cases based on the user goal technique. Draw a use case diagram for these use cases.

3. Using the event decomposition technique for each event you identify in the description here, name the event, state the type of event, and name the resulting use case. Draw a use case diagram for these use cases.

Answer 1

1. Here are the actors who will be using the system:

• Bill Wiley who was the owner and manager
• Delivery person
• Warehouse person
• Customer

2. Bill Wiley

• Enter a solicitation for pickup
• Enter the package pickup data
• Print mark (might be a piece of pickup, or may demand freely)
• Print bills
• Enter installments

Delivery person

• Enter the package pickup information
• Enter the package delivery information

Warehouse person

• Scan the package

Customer

• Sign for delivery

3.

Event	Type	Use
Request the package pickup	External	Enter pickup request info
Pick up the package	External	Enter package info
Time to print bills	Temporal	Print customer bills
Receive payments	External	Enter payment info
Package scanned in warehouse	External	Scan package info
Deliver the package	External	Enter delivery info

It is fascinating for this situation the occasion decay yielded fewer use cases. Individual use cases (Print label and Sign for delivery) are a piece of different business occasions and don't promptly appear.
