Requirements
Problem Statement Operating Environment Intended Users and Uses Assumptions and Limitations Expected End Product and
Other Deliverables
Problem Statement
To develop a system that will greatly reduce the amount of paper that a restaurant uses.
Operating Environment
To be used indoors Stored indoors
Intended Use and Users
Use– To take orders– Payment of orders– View orders to cook
Users– Servers– Cooks– Managers– Customers
Assumptions
Products already exist Product will not be state of the art The end product will not be small 12 handhelds to be used at once Bluetooth range is 10m There will be 5 simultaneous transmissions Handhelds recharged throughout the day Central Computer located centrally in the restaurant. Model can be developed into a handheld.
Limitations
Wireless and Bluetooth distance Power supply Memory and processing speed Size of the monitor for the kitchen The cost of the items for the project The lack of programming skills of the group

Recommendations Regarding Project Continuation/Modification
Project Continuation Project Modification
– Handheld– Central Computer
Project Continuation
Handheld– Secure wireless communication with VPN– Give ability for server to sign-in and out of the handheld– Create a prototype– Make the GUI more robust by including all available
possibilities of a dish Central Computer
– Add a VPN server to the central computer– Create a more robust database– Create a more robust GUI
Project Modification
Handheld– Replace the HDK with an eBox-II due to expense– No touch screen due to use of eBox-II
Central Computer– No change to the design necessary
Summary
Device will not be a marketable product Concept will be proven Servers will carry a wireless handheld device:
– place orders– receive payments– print receipts
Device will include:– LCD touch screen– magnetic card swipe– Bluetooth printer
This will reduce paper used and increase efficiency. Restaurants may find the idea of this device to be an
attractive option.
