Assignment: Developing Use Case

Consider the following scenario, where you have interviewed, summarized, and confirmed the following facts with the owner of a small catering firm:

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 process. PUR has a set of ten standard menus. When potential customers call, the receptionist describes the menus to them. If the customer decides to book a picnic, the receptionist records the customer information (e.g., name, address, phone number, etc.) and the information about the picnic (e.g., 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 (often a credit card or by 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 that 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 mail special offers to them. The owner also wants to track the picnics on which PRU sent a contract, but the customer never signed the contract and actually booked a picnic.

The Exercise: Create a WORD document which you will submit for grading, and will contain the following deliverables:

o From the interview notes, develop a listing (in outline form) of functional and/or non-functional requirements. (See the slide in the Chapter 3 SAD deck.) Note that this is your first draft of a Software Requirements Specification (SRS).

o Develop a Use-Case Overview diagram, showing your use cases derived from the requirements definitions in your SRS. Be sure to note any Extends and/or Includes relationships in your diagram. Note that you may use any tool of your choice; however, you must create a PDF of your diagram, and attach in your Word document. I would also like you to submit the application-specific file Lucid, Visio, paradigm, etc. as part of your submission as well.

o Develop a Use-Case description, using the Use-Case Template, for only the use case of booking a picnic from a customer call. You will have only ONE Use-case document in this part of the assignment.

Compile all of the above parts, except the application-specific diagramming file, into the submission document. Submit both files into the assignment.
