Usability element is fundamental to an effective and user focused web design, so much so that it can make or break the whole look and feel of web design. Usability element should be tested rigorously before making a website live. Now the question is that how we can effectively test the usability in web design? A simple technique is by listing the user tasks.
Listing the user tasks is quite simple but very effective method to test usability element in web design. In this technique all the tasks that a user can perform are listed and then different possibilities for performing those tasks from user perspective are analyzed. The whole idea is to facilitate user so that s/he can perform tasks of interest in the easiest way possible.
This testing technique is simple but its outcome and eventual effect on website can be huge. Because at the end of the day, a website is a tool for the people, and people don't like using annoying and difficult tools!
