Usability Engineering

"The purpose of Jakob Nielsen's Usability Engineering is to help nontechnical people improve the systems so that they are not only error-free but also easier and more pleasant to use, and more efficient. It is a book that ...shows us how to change the world and does so admirably....One of this book's strengths is that it provides a wide selection of methods for improving systems, and allows for the unavoidable constraints of the real world." --NEW SCIENTIST
