Question { 7394 }

what is usuability testing ,when and how is it done


Answer

Usability testing is a technique used to evaluate a product
by testing it on users.

Adv : It gives direct input on how real users use the system

Method :
Setting up a usability test involves carefully creating a
scenario, or realistic situation, wherein the person
performs a list of tasks using the product being tested
while observers watch and take notes

Ex : For example, to test the print function of a payroll
system.
A scenario would describe a situation where a person needs
to print his payroll details, and ask him or her to
undertake this task. The aim is to observe how people
function in a realistic manner, so that developers can see
problem areas, and what people like while using that
application.
