Need "Therapy" for Your "Information Pain"?
ACM Ubiquity: In interview with Louis Rosenfeld co-author of Information Architecture for the World Wide Web (O'Reilly). According to Rosenfield "You can test aspects or components of an information architecture. But you can't quantitatively evaluate the whole beast, save for some extremely narrow and focused situations. For example, you can test the relative speeds of both Land's End's and REI's search engines by looking up the same blue parka. But you can't measure the performance of the architecture itself. It's made of too many individual components that make up each site's architecture (including various browsable taxonomies, search functions, labeling schemes, navigational approaches and interface widgets). Users interact with many or all of these components as they look for information in a site, and it's impossible to ascertain their collective performance." (2001-06-17)
