Quotes from such works as The Phantom Tollbooth, Wayfinding in Architecture, The Hobbit, and Yogi Berra are used to point out the challenges faced by those responsible for effectively managing Web sites for maximum usability. For instance, navigating a web site user-friendly and efficiently can be particularly difficult when the Web site does not demonstrate a full understanding of how to provide the wayfinding devices needed to help web site visitors find their way. In going to a new web site, the user must be able to create a cognitive map that is based on the cues provided in the web site that allows development of mental orientation needed for effective and efficient site navigation and use. Without those cues, users may get frustrated in their navigation and leave the site. Other requirements for effective navigation are described, including building wayfinding abilities at the time of web site design, information sequencing and timelines, and wayfinding support systems and standard site frameworks (template, core navigation, labeling, graphics, and copy placement). For instance, standards must be flexible because needed changes are to be expected, and a flexible wayfinding system allows introduction of new categories of information while leaving standard navigation elements unchanged. This is significant, because users should not be forced to 'refamiliarize themselves with the site each time the site expands or changes.
