Hai....
Usability testing is a black-box testing technique. The aim
is to observe people using the product to discover errors
and areas of improvement. Usability testing generally
involves measuring how well test subjects respond in four
areas: efficiency accuracy recall and emotional response.
The results of the first test can be treated as a baseline
or control measurement; all subsequent tests can then be
compared to the baseline to indicate improvement.
* Performance : How much time and how many steps are
required for people to complete basic tasks? (For example
find something to buy create a new account and order the
item.)
* Accuracy : How many mistakes did people make? (And were
they fatal or recoverable with the right information?)
* Recall : How much does the person remember afterwards or
after periods of non-use?
* Emotional response : How does the person feel about the
tasks completed?
Is the person confident stressed?
Would the user recommend this system to a friend?
*Intuitiveness: How easy was it to learn?
K,Byeeee...
