Abstract:
Usability inspections in early stages of the development process help revealing problems that can be corrected at a lower cost than at advanced stages of the development. The MIT 1 (Model Inspection Technique for Usability Evaluation) is a usability inspection technique, which aims to anticipate usability problems through the evaluation of use cases. This technique was evaluated using a controlled experiment aimed at measuring its efficiency and effectiveness, when compared to the Heuristic Evaluation (HEV) method. According to quantitative results, the MIT 1 exceeded the HEV in terms of effectiveness and obtained a similar performance in terms of efficiency. In other words, the MIT 1 allows finding more problems than the HEV. On the other hand, the subjects spent more time finding these problems using MIT 1. Moreover, the MIT 1 was considered easy to use and useful by the subjects of the study. We analysed the qualitative data using the procedures from the Grounded Theory (GT) metho
d and results indicate improvement opportunities.
