These categories are measured by the percent that complete the task, how long it takes to complete the tasks, ratios of success to failure to complete the task, time spent on errors, the number of errors, rating scale of satisfactions, number of times user seems frustrated, etc.
The interface will allow the user to perceive that they are in control and will allow appropriate control. Field observations are taken at a site of a possible user, which track the artifacts of work such as Post-It notes, items on desktop, shortcuts, and items in trash bins.

Error prevention Even better than good error messages is a careful design which prevents a problem from occurring in the first place.
