Re: measurements of usability
Real basic metrics can be:
Efficiency= Time on Task. You should have a requirement that each task should take x amount of minutes or seconds. Then record the actual "time of task" for each tester during the usability test to see if your design has hit the requirement or not.
Ease of use= Did the tester complete the task correctly?
Satisfaction= Record the testers comments and behavior. Did they have negative comments to say? Were they frusterated trying to complete the task?
