Slide2: 

WAITer Waiting Assistant Information Technology WAITer is a handheld computer application designed to increase the efficiency of the processes involved in taking a restaurant order. This process begins with a server taking an order and ends when a customer pays for the bill. Our application will achieve this goal by revamping the ordering process to provide quick service for customers while simultaneously ensuring a more cost effective and efficient turnover of patrons for restaurateurs.

Current Problems & Proposed Solutions

Slide5: 

Representative Tasks EASY: A customer has a complaint and wishes to speak with a manager. Contact Bob and ask him to go to Table 5. Very straight-forward and serves as a good introduction to the system MEDIUM: Four customers have been seated at Table 1. They already ordered 2 Cokes and an Evian water. Please add a turkey burger with no mayonnaise to the order, send all the orders off to the kitchen immediately and process a cash payment. This task takes you through the entire process of serving a table, from ordering to processing the bill.

Slide6: 

Representative Tasks HARD: Cindy, a customer at Table 3 complains that her steak was overcooked. She doesn't want another steak so you need to subtract it from her bill. In addition, in order to comply with the restaurant policies, the customer is entitled to a free dessert. Cindy wishes to have the apple pie. Place the dessert order, but do not add the charge to her bill. This task uses some of the more complicated features of the application, such as changing prices. It also builds upon the previous task since users have to use the menu again and remember to send the order to the kitchen.

Slide7: 

Transition between Lo-Fi and Hi-Fi vertical toolbar merged w/ horizontal toolbar “flat” menu improved using eVB’s treeview ctrl “order” tab changed to “view order” due to confusion with “menu” tab associating ordered items w/ individuals removed since it slowed down the order-taking process messaging utility now has option to use keyboard input in addition to handwriting recognition messaging utility increased from 1 to 2 frames due to space required by pop-up keyboard
