Books

Usability Engineering, Jakob Nielsen
This is the premier text on software usability. Although it was written years ago, the principles and premises apply just as aptly to the web today. The book gives concrete, actionable methodologies and tools to improve the ease of use, usefulness and satisfaction of a system.

Designing Web Usability: The Practice of Simplicity, Jakob Nielsen
This book segments discussions of web usability into page, content, site, and intranet design. Nielsen uses research and many examples to communicate his guidelines.

Emotional Design: Why We Love (Or Hate) Everyday Things, Donald Norman
This is a book to inspire and evangelize. It's more of a why book than a how book, as in "why are we drawn to some objects more than others?"

Cost-Justifying Usability, Randolph G. Bias and Deborah J. Mayhew
If you are trying to convince your organization of the need for usability, Cost-Justifying Usability is the book for you. It gives the business case for why and how usability saves companies money in the long haul. The book has many case studies and techniques for quantifying usability.

Don't Make Me Think: A Common Sense Approach To Web Usability, Steve Krug
Includes tips, techniques and examples of website design. It covers topics such as user patterns, navigation design and home page layout, as well as user testing.

Jakob Nielsen's Alertbox is an archive of bi-monthly columns about specific issues in usability. Browse through articles to find out about guidelines, research results, and methodologies.

"Maximizing Windows" is the best article on single-use web applications (applications used just once, or very infrequently). It's also one of the best arguments for iterative user testing.

"How Usability-Focused Companies Think" gives great advice on how and why to implement user-centered design for the betterment of your users—and your sales.

Organizations and Associations

SIGCHI (Special Interest Group on Computer-Human Interaction) is the premier international society for professionals, academics and students interested in human-computer interaction (HCI).

UPA (The Usability Professionals' Association) supports those who promote and advance the development of usable products. Members come from across the broad family of disciplines that create the user experience. It's less academic than SIGCHI and focuses more exclusively on usability.

HFES (Human Factors and Ergonomics Society) promotes the discovery and exchange of knowledge concerning the characteristics of human beings that apply to the design of systems and devices of all kinds. The group focuses broadly on human factors and ergonomics as they apply to a range of systems, including software applications, websites, aeronautics and cars.

 

Books

Bringing Design to Software, Terry Winograd
This collection of essays provides essential inspiration for reflective software designers driven by practical concerns of what works, what doesn't, and why. Contains contributions by such insightful software engineers as David Liddle, Don Norman, John Bennett and Michael Schrage.

The Design of Everyday Things, Donald Norman
An inspiring book that gets everybody thinking in a different way about how users interact with and experience anything that's designed.

The Art of Human-Computer Interface Design, Brenda Laurel
A collection of essays from industry luminaries such as Alan Kay, Nicholas Negroponte and Ted Nelson. Don't expect to read it for hard-and-fast advice on solving your programming problems, but do expect to gain new perspectives on how your users view your applications and what they expect from a computer.

Envisioning Information, Edward Tufte
One of the most-cited design books. Tufte presents examples of good and bad information design and deconstructs why they work—or don't.

Designing Visual Interfaces: Communication-Oriented Techniques, Kevin Mullet and Darrell Sano
An excellent introduction to the design theories involved in the creation of user interfaces. Instead of using the usual examples and pictures of computer screens and application menus, the book approaches the concept of UI from its "outside world" roots. Examples include street signs, corporate logos, and the map of the London Underground.

"Graphic Design for User Interfaces" is a short overview from Georgia Tech of basic tips for creating visual design. It's a good place for beginners to start.

Organizations and Associations

AIGA is the professional association for communication design. It is committed to furthering excellence in communication design as a broadly defined discipline, strategic tool for business and cultural force. AIGA is the place design professionals turn to first to exchange ideas and information, participate in critical analysis and research, and advance education and ethical practice.

InfoDesign is a site dedicated to interaction and information design for those in the trenches. It has more than 20 sub-categories of information, including accessibility, content, mobile design, navigation and more.

GUUUI is a site for people engaged in the various fields of making the web a better experience for the users. At GUUUI, you'll find weekly postings and quarterly articles about interaction design, information architecture, usability, visual design and the like. GUUUI is a private project and isn't sponsored or initiated by any private or public organization or company.

 

"Return on Investment for Usability," Jakob Nielsen
This is one of the definitive articles on the incredible value of usability to organizations. Nielsen quantifies the value several ways. An excerpt:

Following a usability redesign, websites increase usability by 135% on average; intranets improve slightly less.

ROI of Usability, UPA
The Usability Professionals' Association has compiled a list of statistics and anecdotes on how usability can save money. Two excerpts:

The average UI has some 40 flaws. Correcting the easiest 20 of these yields an average improvement in usability of 50%. The big win, however, occurs when usability is factored in from the beginning. This can yield efficiency improvements of over 700%.

With its origins in human factors, usability engineering has had considerable success improving productivity in IT organizations. For instance, a major computer company spent $20,700 on usability work to improve the sign-on procedure in a system used by several thousand people. The resulting productivity improvement saved the company $41,700 the first day the system was used. On a system used by over 100,000 people, for a usability outlay of $68,000, the same company recognized a benefit of $6,800,000 within the first year of the system's implementation. This is a cost-benefit ratio of $1:$100.
