Tasty Burger Restaurant - Development Of An Information System For TBR - Case Study Assignment Help

Assignment Task:

System Information

As university students in the 2000s, Peter and James often dreamed of starting their own business. While on their way to an ICT class, they drove by Hungry John’s Family Restaurant and noticed a “for sale” sign in the window. Peter and James quickly made arrangements to purchase the business, and Tasty Burger Restaurant (TBR) was born. The restaurant is moderately sized, consisting of a kitchen, dining room, counter, storage area, and office.

Currently, all paperwork is done by hand (that is, the current information system is totally manual). Peter and James have discussed the benefits of purchasing an external software package; however, Peter wants to hire a software project team to help tailor-make a system for TBR. Perishable food items, such as beef patties, buns, and vegetables, are delivered daily to TBR. Other items, such as napkins, straws, and cups, are ordered and delivered as needed. Peter receives deliveries at the restaurant’s back door and then updates a stock log form, which 2 Peter uses to help track inventory items. Peter updates the stock log form when deliveries are received and nightly after daily sales have been tallied.

Customers place their orders at the counter and are also called when their orders are ready. The orders are written on an order ticket, totaled on the cash register, and then passed to the kitchen where the orders are prepared. The cash register is not capable of capturing point-ofsale information. Once an order is prepared and delivered, the order ticket is placed in the order ticket box. Peter reviews these order tickets nightly and makes adjustments to inventory. In the past several months, Peter has noticed various problems with TBR’s current information systems, especially with the inventory control, customer ordering, and management reporting systems.

Because the inventory control and customer ordering systems are paper-based, errors often occur. These errors frequently affect delivery orders received from suppliers as well as customer orders. Peter has often wanted to have electronic access to forecasting information, inventory usage, and basic sales information. This access is impossible because of the paper-based system.

Task 1 (UML Modeling Diagrams)

• Assume that you have chosen the object-oriented (O-O) analysis approach for systems development. Draw the following four UML diagrams to capture users’ requirements. Note that these diagrams should be drawn for the new system to be developed, not for the existing manual system.

Produce the following UML diagrams for the new system:

(a) A Use Case Diagram: It should show all the critical use cases in the entire system.

(b) A Domain Model Class Diagram: It should include all important classes needed in the entire system.

(c) An Activity Diagram: You only need to draw an activity diagram for those tasks related to customer ordering and fulfillment.

(d) A System Sequence Diagram: You only need to draw a system sequence diagram for those tasks related to stock (e.g., beef patties, buns, vegetables, napkins, straws, and cups) ordering and replenishment.

• Each of the above diagrams should be accompanied with clear explanations and assumption(s).

Note that when developing each diagram, you may make some assumptions which will affect the results of your presented modelling diagrams.

For examples:

• When analyzing TBR’s business processes, there are usually some issues which need to be clarified before you can proceed, particularly when the issues affect the way you developed your models.

• In practice, you would simply ask the users for clarification. In this assignment, however, you should make “reasonable” assumptions of what you believe the users would advise you and list those assumptions here. After developing.
