Description The order tab is where the user will be able to review the items they have decided on and also add preparation notes or special requests. The order can be sent by pressing “send my order.” Within the Scenario The four friends will simply look over this page to make sure it is what they ordered, adding preparation notes as they wish. They will press the send button to place their order. Usability Analysis Learnability The order tab is great in terms of learnability. First, there is a list of all items and preferences that the user has selected. It is also very simple in that there is only the list and a send order button. Efficiency It is also very efficient, mainly in its simplicity. There is only a list and a button so not much in terms of efficiency issues. Safety The only issue with safety with this order tab is that orders are final and can only be changed if the waiter/waitress is called over. |

Entertainment Tab 
It will simply be two icons, web and games. Learnability is not really an issue here. Efficiency Efficiency is not an issue for this tab because it is all outside our design after a user selects either game or web. Safety Safety is not an issue for this tab because they can easily go to the tab they meant to go to instantly. |
