If you develop web sites, you need to be doing usability testing. It
is that simple.
When you write a program using your favorite language, do you expect
the program to work correctly the first time? No, none of us do. We
all know the importance of testing our software as we develop it.
Your web interface needs testing as well. Web developers and graphic
designers,while talented, aren't like the general population. We think
different. We have an entirely different vocabulary. Designing systems
that make sense to code warriors will often lead to a site that is not
usable by the average person.
This tutorial will teach you how to conduct a simple usability test on
your web site (using the hands-on task based method). While the method
explained here is not comprehensive, the return on investment is very
steep. Consider the wise words of a well known usability expert:
"It takes only five users to uncover 80 percent of high-level
usability problems" Jakob Nielsen
