Usability Engineering

Jakob Nielsen, 1993

Detailing the methods of usability engineering, this book provides the tools needed to avoid usability surprises and improve product quality. Step-by-step information on which method to use at various stages during the development lifecycle are included, along with detailed information on how to run a usability test and the unique issues relating to international usability. This book emphasizes cost-effective methods that developers can implement immediately, and instructs readers about which methods to use when, throughout the development lifecycle. Also includes strategies to avoid the four most frequently listed reasons for delay in software projects, detailed information on how to run a usability test, and an extensive bibliography allowing readers to find additional information. (Published by Morgan Kaufmann, San Francisco; ISBN 0-12-518406-9 slightly expanded paperback edition. Original hardcover edition published by AP Professional.)

New Scientist review: "It is a book that does not moan about how bad things are but shows us how to change the world and does so admirably."
