© Rob Schlender & Hamed Esfahani Operational Concepts StadiumFood is an application run on a small portable device that can support java midlets. The application provides an interface for the user to order coffee (future food products are planned for a later release) at a stadium. The concession stand has an Internet connection that displays the orders requested. An attendant then delivers the order to the user.

© Rob Schlender & Hamed Esfahani System Requirements Customer: The customer will have a java midlet enabled device. Often a PDA, or cell phone. Concession Stand: The backend will consist of a web server and a computer at each concession stand that wants to deliver products.

? Who wants it? All hungry, sports loving, owners of java midlet enabled devices

© Rob Schlender & Hamed Esfahani Who will support it? Stadium owners can have the system in place and rent it to different concession stands Concession stand owners may choose to invest in this system individually Users will pay a fee for using the system It is both a marketing strategy and a convenience for the businesses using the system

© Rob Schlender & Hamed Esfahani Feasibility Rationale Without using a database we have considerable concurrency issues - can be solved by synchronizing access to a shared file Time constraint with the amount of work that needs to be done - At least five people will be required to work on this project Will enough sport fans carry a midlet enabled device and be willing to pay for the fee
