Usability Testing Essentials provides readers with the tools and techniques needed to begin usability testing or to advance their knowledge in this area.

It then reviews testing options and places usability testing into the context of a user-centered design (UCD). It goes on to discuss the planning, preparation, and implementation of a usability test.
