In the first wave of e-commerce, the challenge for designers was to create new websites for clients. Now that challenge has changed. To meet the shifting demands of the digital marketplace companies are asking designers to help them upgrade of revamp their existing sites - an entirely different and often much more difficult proposition. Featuring in-depth case studies of 22 redesigned websites, this book uses a before-and-after model to reveal the purpose of the original site, the reasons it was no longer effective and the specific ways each designer solved those problems through redesign. Screenshots illustrate the old and new designs for each site and useful sidebars address more general themes: determining how drastic a redesign should be, orchestrating a site redesign following a merger and changing the central purpose of a site (such as changing from an interactive site to an informational one).
