Visio - the interaction designer's nail gun (2nd edition) (24 Jan 2006)
Imagine that you've made a prototype with a lot of pages and realize that you need to add a new item to the global menu. Doing this normally means adding the menu item to each and every page in the prototype. In Visio, you can place the elements shared by multiple pages on a shared background. This allows you to make changes that affect all the pages by altering just the background. And Visio takes this even further by supporting layering of backgrounds on backgrounds. This enables you to have a background with a global menu and backgrounds with sub menus for the sub sections of a web site. More about that later on.Add this article to Del.icio.us
