In addition to traditional usability issues, evaluation studies for personalized Web sites and applications must consider concerns specific to these systems. In the general case, usability studies for computer-based applications attempt to determine whether the software, in actual use, meets users’ needs; whether users can accomplish their goals in using the software; whether users can understand and use the application (whether they comprehend what they can do and how); the rate, frequency, and severity of user errors; the rate of and time duration for task completion; and so on.
