Usability testing is a formal study in which 10 to 12 participants are observed individually performing tasks with a system. Findings and recommendations are made according to performance data gathered during the test:

• number of errors
• task times
• problems
• assists

The purpose of the usability test is to identify design flaws. A usability test is the only way you can be reliably sure that your design will be accepted, used, and will meet the users’ needs.
