What is our Objective? Implementing a point of sale client and back office server to assist in sales and transactions in a small business or restaurant/bar. Implementing a point of sale client and back office server to assist in sales and transactions in a small business or restaurant/bar. The program will be easy to use, reliable, and secure. It also will be fully customizable by the administrator. Customizable buttons, menus, and users. The program will be easy to use, reliable, and secure.

Goals The ability to have security, ease of use, and power over how they want the application to function will be our selling point.

System Requirements Back Office Server Client Workstation PDAs (Optional) Kitchen Display (Optional)

Back Office Server 1.Add new items to the database. Give them prices and place them in appropriate menus so that the client machine can browse for the item, select with the press of a button. 2.Edit existing items in database: ie change prices, change descriptions. 3.Print single users, daily, weekly, monthly, and yearly reports. This feature gives the manager information on the day to day sales helping in planning and monitoring what sells and what doesn t. Also can monitor transactions 4.Inventory. Can view inventory of items. Also can give an optional reminder if quantity of a certain item gets to a certain amount. 5.Add users to the system giving them unique login codes 6.Customer tracking: names, address, history We will be using as the bare minimum for the suite two computers. One running the back office server which can:

Client Workstation 1.Easy to use menus to browse and select items to include in an order or transaction. 2.Editablity. At anytime the employee wants to change an order, he or she can select the item they want to edit and delete or modify it. 3.Option of scanning barcodes to ring things in 4.Option of entering a SKU number to ring things in as well. 5.GUI split into a 2 x 2 grid. Bottom right is the number pad to enter quantities, amount of money received from customer, and other helpful things. 6.Bottom left will include a summary of all items added to the transaction with quantities, prices, descriptions as well as a total before tax. The top will have a main menu and other useful crap.

PDAs An optional feature that can be brought to the table or around the store to take orders. Same functionality as the terminal but portable Same functionality as the terminal but portable

Kitchen Display An optional feature Only used to display orders

Our Model Evolutionary Prototyping Model. Evolutionary Prototyping Model. Since we have a very GUI motivated system it is good to have an evolution of prototypes to be able to convey to our clients what they are getting and to get input about the system.

Feasibility Rationale What are our assumptions? What are our risks?

Assumptions Assumptions: –Java/C# has support for input from barcode and scanners. –It will actually be easy to use. –Waiter/Waitresses will actually want to use PDA s rather than traditional methods (i.e. using paper pads or remembering orders).

Risks Risks: –Does the team have enough GUI programming knowledge? –Does the team have enough database programming experience? –Does any member of the team have actual experience using a POS system? –Clients may be using a POS client already and unwilling to change because are satisfied with features and have already learned how to operate it sufficiently.
