Steve Krug

Steve Krug

#36 “Form follows function – that has been misunderstood. Form and function should be one, joined in a spiritual union.”

Frank Lloyd Wright

#37 “Usability is not everything. If usability engineers designed a nightclub, it would be clean, quiet, brightly lit, with lots of places to sit down, plenty of bartenders, menus written in 18-point sans-serif, and easy-to-find bathrooms. But nobody would be there. They would all be down the street at Coyote Ugly pouring beer on each other.”

Donald A. Norman

#42 “Even the best designers produce successful products only if their designs solve the right problems. A wonderful interface to the wrong features will fail.”

#56 “Directories – such as Yahoo and Looksmart – often reject sites with broken links. Studies show that 71% of Web sites have at least 1 bad link.”


#57 “Usability answers the question, “Can the user accomplish their goal?”

Dr. Joyce Lee

#58 “Usability, fundamentally, is a matter of bringing a bit of human rights into the world of computer-human interaction. It’s a way to let our ideals shine through in our software, no matter how mundane the software is. You may think that you’re stuck in a boring, drab IT department making mind-numbing inventory software that only five lonely people will ever use. But you have daily opportunities to show respect for humanity even with the most mundane software.”

Joel Spolsky

#59 “Usability plays a much wider role in our lives than most people realize. It’s not

just about using a website, a piece of software, or the latest technology. Usability is

about setting up a tent, relighting a furnace to heat a home, trying to figure out a

tax form, or driving an unfamiliar rental car. Usability impacts everyone, every day.

It cuts across cultures, age, gender, and economic class.”

Thomas Tullis

#60 “Usability cost-benefit data shows that including usability in product development actually cuts the time to market and increases sales because usability and ease of use build quality into products and catch many expensive problems early on in the cycle when they can be addressed at lower cost. Finally, working with users from the beginning of a product cycle ensures that the product is being designed so that users will be satisfied.
