Linda's Design

I illustrate my design using a Microsoft Visio file. The file contains a number of pages, which corresponds to McInterface's screens. Double clicking the yellow buttons on any page will bring you to another page. This feature in Microsoft Visio helps me to illustrate the interaction. In addition to this file, I also supply a page/screen that will come up when the subtotal of MyTray is greater than the McCard's value. You can view the main interaction flow chart of my design by clicking here.

I will explain how you will go through my design in each of our scenarios in the following. First, you need to open my Visio file, and click the 'Page-1' tab on the bottom, which will show you the initial page of the McInterface. I suggest that you print this webpage as your guidelines while you go through the visio file. Please note that the data and pictures in my visio files are just examples. They do not change as we go through the scenarios.
