Page Description Diagrams July 8, 2012 In a page description diagram, the content areas of the page are described in prose, as in a functional specification. The content area descriptions are arranged on the page in priority order. Typically, I will define the horizontal axis of the diagram as the page priority. Thus, content areas described on the left side of the page are higher priority than those on the right side of the page.With this approach, the diagram represented the two main issues: priority and content. I found that I could include layouts of individual content areas to show, for example, how the “check flight status” form might look. These mini-layouts helped our client visualize the interactivity, but did not lock the designer into any particular approach. Our conversations with the client focused on the nature of the content and functionality and the relative priority of the page contents.
