This study investigated the effectiveness and efficiency of three usability evaluation and inspection techniques: heuristic (expert) evaluation, checklist-based approach, and empirical user testing using two pen-based Personal Digital Assistants (PDA's) as a case study. The purpose of the study was to provide insight into the major differences, advantages and disadvantages of these three approaches, as this is of interest to human factors practitioners. From the findings, heuristic and checklist evaluation approaches were able to identify many usability problems in a cost-effective manner. Our study demonstrated that user-based evaluations offer much more information on the nature of usability issues, and seem to provide a greater diagnostic value as far as development is concerned.
