Metodología cuantitativa para la evaluación y comparación de la calidad de sitios web

This research is aimed at defining and discussing a quantitative methodology, the one integral, robust and flexible, for the quality evaluation of Web-based applications. The methodology, from now on called Web-site Quality Evaluation Method (Web-site QEM) is intended to perform an engineering contribution proposing for such an end a systematic, disciplined and quantitative approach customized to the evaluation, comparison and analysis of the quality of more or less complex Web artifacts. We analyze their phases and activities, we describe the produced deliverables, and we present models, methods, procedures, approaches and tools to apply in these activities. We outline the approach and its solutions, using along the thesis two case studies for Web sites, and other carried out field studies. Also, we present a conceptual framework for metric validation and we discuss the theoretical validation of some utilized metrics in the Web evaluation process. Finally, we describe thoroughly an evaluation process model to which Web-site QEM can adhere. Some additional aspects and studies are presented in annexes.
