Usability and Reliability of the User Action Framework: A Theoretical Foundation for Usability Engineering Activities
MetadataShow full item record
To be an effective classification and reporting tool, the UAF should be usable and reliable. This work addressed two important research activities to help determine the usability and reliability of the User Action Framework. First, we conducted a formative evaluation of the UAF Explorer, a component of the UAF, and its content. This led a re-design effort to fix these problems and to provide an interface that resulted in a more efficient and satisfying user experience. Another purpose of this research was to conduct a reliability study to determine if the User Action Framework showed significantly better than chance agreement when usability practitioners classified a given set of usability problem descriptions according to the structure of the UAF. The User Action Framework showed higher agreement scores compared to previous work using the tool.
