The Economics of Usability
Wednesday, May 30th, 2007One way to measure usability today is with time. How much time does it take someone to find a link on your web site? How much time does it take for a person to figure out how to send a text message with your new cellphone?
Every person has, to some degree, a perception of time as a limited resource. As we know, resources that are limited tend to become more valuable. Although the perception of time is flexible, people place a value on their time. At least unconsciously, people will try to weigh spending time on your user interface vs. the perceived potential benefit.
