In order to help users (and ourselves) better understand the information architecture of our system, we created a site / system map. This artifact shows the interaction possibilities of our application and physical components (the transceiver, keypad and fob). Our sitemap acts as both a tool for our design planning and a tool for visually representing our system to users. In time, the connections outlined in this sitemap were used to organize the screens used in our paper prototype and annotated wireframes.
