A usability session usually lasts about two hours and is
videotaped. Later, the video will be studied to find areas in the product
that need improvement. Usability Specialists are interested in the amount
of time it takes to complete a task, the number and severity of errors
made and their cause, and how satisfied the user is with the product's
design.
It is important to remember that it is the product that
is being tested, not the user. The user's feedback is very important in
evaluating and improving the product.
