Abstract
The challenge of developing more usable Web applications has promoted the emergence of several usability evaluation methods. However, there is a lack of empirically validated methods that can properly be integrated during the early stages of Web development processes. This has motivated us to propose a Web Usability Evaluation Method (WUEP) which can be integrated into model-driven Web development processes. This paper presents the first steps in the empirical validation of WUEP through a controlled experiment. This experiment was designed in order to evaluate the effectiveness, efficiency, perceived ease of use, and satisfaction with WUEP in comparison to a widely-used inspection method: Heuristic evaluation (HE). Results show that WUEP is more effective and efficient than HE in the detection of usability problems in artifacts obtained from a model-driven Web development process. The evaluators were also satisfied when applying WUEP, and found it easier to use than HE.
