Abstract: In the recent decade, usability prediction has become a relevant research field. It is also helpful in enhancing the software quality. This study is an extension of the research done by the same researchers. In this study, we are predicting the total usability of a web application using multistage fuzzy system. To reduce the total number of fuzzy rules, the fuzzy system can be multistage by grouping the usability factors. In this research, initially a dataset for ‘Live Auction’ web application is created and made it publicly available, then the total usability is predicted for the same using multistage fuzzy system. The ranking of players has been implemented using SOWIA-MOORA method in the created dataset.
