Second-Interactive Prototype

Limitations

1. We still have not finished building up all the menus. For example, even though we added the New Taste and Mini Meal Deal food categories, but clicking on their tabs would still not present their items. Also, we have not added options for salad dressings, Desserts' sizes, and sauces for Nuggets.

2. In the View Order/Check Out page, we use radio buttons to allow user to choose between cash, ATM card, and credit card payment methods. Suppose you choose to pay by cash, but then in the cash page you click cancel to go back to the View Order/Check Out page, the radio buttons will be reset to the default choice (credit card payment).

3. Error control system is still deficient. For example, if the user has not ordered anything, but still click on the View Order/Check out button, he/she is still able to proceed. Our intention is not to allow the user to check out and a warning message should be displayed.

4. If we change the quantity of the item ordered to zero, the item will still remained in the Order Summary. Our intention is to have the item removed if its quantity is zero.

5. If we select another toy for the Happy Meal but then we click cancel in the Order Details Page, we will still see the same toy we select. Our intention is to have the toy changed back to the one selected before we make any changes.

6. The Size combo box on the menu display does not show the right size choices for some food categories, such as the Beverage.

7. The current prototype did not provide any feedback for "More Ketchup" and "No Ice" special requests. We will implement this using small icons on the Order Summary of the next prototype.

8. The graphics and screen background design in the current prototype are not finalized yet.

9. The Happy Meal Toy is currently displayed in a separate form. We plan to display the toys on the same form where we display the food items.

10. The size display of the beverage menu is not big enough. The size prices for some categories are also not displayed on the menu page, only inside the combo box, such as for Salad. We plan to fix this before we do the usability testing.
