Question

A systems analyst has collected the following information about a project to work on for a small

catering business.

Picnics R Us (PRU) is a small catering firm with five employees. During a typical summer

weekend, PRU caters fifteen picnics with twenty to fifty people each. The business has grown

rapidly over the past year, and the owner wants to install a new computer system for managing

the ordering and buying processes. PRU has a set of ten standard menus. When potential

customers call, the receptionist describes the menu to them. If the customer decides to book a

picnic, the receptionist records the customer information (name, address, phone number), and the

information about the picnic (place, date, time, which one of the standard menus, total price) on a

contract. The customer is then faxed a copy of the contract and must sign and return it along with

a deposit (a credit card number or a check) before the picnic is officially booked. The remaining

money is collected when the picnic is delivered. Sometimes, the customer wants something

special (e.g., birthday cake). In this case the receptionist takes the information and gives it to the

owner, who determines the cost; the receptionist then calls the customer back with the price

information. Sometimes the customer accepts the price; other times, the customer requests some

changes that have to go back to the owner for a new cost estimate. Each week, the owner looks

through the picnics scheduled for the weekend and orders the supplies (e.g., plates) and food

(e.g., bread, chicken) needed to make them. The owner would like to use the system for

marketing as well. It should be able to track how customers learned about PRU and identify

repeat customers, so that PRU can email special offers to them. The owner also wants to track the

picnics on which PRU sent a contract but the customer did not sign the contract and actually book

a picnic.
