Improving a Web Usability Inspection Technique Using Qualitative and Quantitative Data from an Observational Study

We have proposed a checklist-based usability inspection technique (WDP - Web Design Perspectives-Based Usability Evaluation) specific for Web applications´ usability evaluation and we are following an experimentation-based methodology to support its development and improvement. This paper describes an observational study conducted, aimed at eliciting how inspectors apply the WDP technique. We discuss the quantitative and qualitative results of the result and their impact on improving the WDP technique. We analyzed the qualitative data using the procedures from the Grounded Theory (GT) method.
