Resumo. Este artigo apresenta uma técnica de inspeção de usabilidade (WDP -Web Design Perspectives-Based Usability Evaluation) e a metodologia experimental utilizada como base para seu desenvolvimento e aprimoramento. Até o presente momento foram executados três estudos experimentais (um secundário e dois primários) que levaram à versão atual da técnica WDP. Resultados indicam que a técnica é viável e que é possivelmente mais efetiva e tão eficiente quanto a Avaliação Heurística proposta por Nielsen. Abstract. This work describes a usability inspection technique (WDP -WebDesign Perspectives-Based Usability Evaluation) as well as the experimentation methodology followed to support its development and improvement. At this point in time, three experimental studies (one secondary and two primaries) were carried out and led to the WDP's current version. Results indicate the feasibility of the WDP technique and its possibility to be more effective than and as efficient as Nielsen's Heuristics Evaluation.

This chapter presents the WDP (Web Design Perspectives-based Usability Evaluation), an inspection technique specifically designed to assess the usability of Web applications. This technique combines Web design perspectives and the heuristic evaluation method proposed by Nielsen (1994b). In addition to describing the components of the WDP technique this chapter also illustrates its use in practice by means of an industrial case study where the technique is applied to inspect a real Web application. In this case study, developers and requirement assessment staff applied the WDP technique to evaluate the usability of modules developed from scratch for a Web application. The results of this case study indicate the feasibility of performing usability inspections with the participation of a software project’s stakeholders, even when stakeholders are not usability experts.
