Given the growth in the usage of Web Applications, the usability of these applications has become a key success factor. There are several technologies to evaluate and improve this quality factor. However, the usability inspections results still depend on the inspector's experience. We have proposed a Web usability inspection approach, called WE-QT (Web Evaluation -Question Technique), a question based technique that aims to reduce the difficulties of inspectors with little knowledge of usability. We are following an empirical methodology to support its development and improvement. This paper presents two experimental studies conducted until this point of the research: a feasibility and an observational study. We discuss the qualitative and quantitative results of both studies and their impact on improving the WE-QT. With this paper we also aim to spread the knowledge about experimental studies to evaluate and evolve a new software engineering technology.

Abstract. The increasing evolution of computacional systems has create new challenges to develop applications that meet the expectations of users to the courses of Information Technology (IT). In this context, the Human-Computer Cenário de usoCom o surgimento de novos paradigmas e tecnologias da informação, saber como criar novas aplicações, que atendam as expectativas dos usuários, exige conhecimento, técnicas, ferramentas e métodos que englobam tanto a Engenharia de Software como a área Interação Humano-Computador (IHC). No desenvolvimento de software, a área de IHC fornece uma visão que foca na qualidade de interação usuário-sistema, para atender de maneira satisfatória suas necessidades e expectativas dos usuários [Benitti e Sommariva 2012]. Por essa razão, o ensino de IHC tem sido cada vez mais difundido em cursos de graduação e pós-graduação na área de Tecnologia da Informação (TI),
