Chapter 5: Evaluating Web Sites
The Goals of Expert Evaluation
There are two goals when conducting expert evaluations of Web sites. The first is to uncover obvious execution flaws with sites, such as poor HTML markup, error prone JavaScript, broken links, and other problems (which should be caught during quality assurance but often are not). The second goal is to find obvious usability problems with a site before conducting user testing.

While the use of quality assurance tools and practical knowledge of the various aspects of the Web medium will help us find execution gaffes, usability problems can be more difficult to ferret out. We need to be mindful of how users think when conducting this part of testing. We need to be particularly careful when making assumptions about purpose, audience, creation method, and so on. If these assumptions are incorrect, the associated conclusions could be equally incorrect.
