Validating the SUE inspection technique

In the usability inspection of complex hypermedia a great deal is left to the skills, experience, and ability of the inspectors. The SUE inspection technique has been proposed to help usability inspectors share and transfer their evaluation know-how, make it easier the hypermedia inspection process for newcomers, and achieve more effective and efficient evaluations. The SUE inspection is based on the use of evaluation patterns, called Abstract Tasks, which precisely describe the activities to be performed by evaluators during inspection. This paper presents an empirical validation of this inspection technique: two groups of novice inspectors have been asked to evaluate a commercial hypermedia CD-ROM applying the SUE inspection or the traditional heuristic evaluation technique. Results have shown a clear advantage of the SUE inspection over the heuristic evaluation, demonstrating that Abstract Tasks are efficient tools to drive evaluator's performance.
