In-Process Usability Problem Classification, Analysis and Improvement
In recent years, more organizations began to ad-dress usability problems to improve their competitive position and foster customer loyalty. Although there are some clas-sification schemes to address usability problems, there is no cause-effect framework to enable in-process usability feedback and improvement. Orthogonal defect classification (ODC) had been widely used in software development process, but with insufficient attention to usability problems. In this paper, we present a classification and analysis framework to integrate usability practices with ODC framework. With our framework, the cause-effect relationship can be identified. By addressing the usability problems during the whole development cycle, human computer interface (HCI) and software process can be improved together. A case study was conducted to demonstrate the viability and effectiveness of our framework.
