Information Architecture is the root of navigation, page layout, and really an entire website or other experience.

Our assigned website was FashionSnoops.com, a trend forecasting website.

When mapping out our assigned website, I noticed that each page did not navigate to a sibling page or jump across the map to a child of another parent page. Each page navigated a level above or below in the tree. This informed my image of IA to be very hierarchical.
