Evolution by Evaluation

This paper describes the process of formally evaluating an E-Learning system that has been in use for several years. Professional usability evaluation offers deeper insight into user behaviour and needs than accidental feedback collection or introspection by system developers. A first analysis of the evaluation samples shows satisfaction of users with the general design of the system but also dissatisfaction with certain aspects of navigation that would otherwise have escaped our attention. State of the art formal evaluation turned out to be instrumental in making an existing system considerably more user-friendly.
