A Practical Guide to Usability Testing
In this volume, the authors begin by defining usability, advocating and explaining the methods of usability engineering and reviewing many techniques for assessing and assuring usability throughout the development process. They then follow all the steps in planning and conducting a usability test, analyzing data, and using the results to improve both products and processes.
This book is simply written and filled with examples from many types of products and tests. It discusses the full range of testing options from quick studies with a few subjects to more formal tests with carefully designed controls. The authors discuss the place of usability laboratories in testing as well as the skills needed to conduct a test.
Included are forms to use or modify to conduct a usability test, as well as layouts of existing labs that will help the reader build his or her own.

Page 4 - Usability means that the people who use the product can do so quickly and easily to accomplish their own tasks.
Page 8 - Usability? Usability is not a surface gloss that can be applied at the last minute. Usability is deeply affected by every decision in design and development. Therefore, usability has to be built in from the beginning.
Page xiv - While academics were developing controlled experiments to test hypotheses and support theories, practitioners developed usabilitytesting methods to refine user interfaces rapidly. Controlled experiments have at least two treatments and seek to show statistically significant differences: usability tests are designed to find flaws in user interfaces. Both strategies use a carefully prepared set of tasks, but usability tests have fewer subjects (maybe as few as three I. and the outcome is a report with...
