USE A/B DSS Tool

An online A/B testing Decision Support System (DSS) for web usability assessment is a tool that helps software designers to compare more than one version of a website, giving to the real end-users and usability experts the possibility to express linguistic opinions regarding the interface, the easiness of use, and some other facets such as the accessibility level. By conducting online usability tests and having a tool to compute several linguistic usability scores, the conductor of the usability test is assisted in the reporting of the web usability assessment.

In this research we also provide a methodology to use Design Thinking methods such as personas and role playing in the given tests. The USE-AB-test DSS is available online under registration and provides a method for the automatic application of the Multi Expert Multi Criteria Linguistic Decision-Making model for US Evaluation (LDM4USE). Building on the widely recognized System Usability Scale (SUS), we fuse collective opinions to provide results regarding the usability of each of the websites in an understandable way. Our proposal is implemented as an A/B testing tool called USE-AB-test DSS, and we have use it to describe a case use for the assessment of three Moodle platforms of the University of Guadalajara, Mexico. This heavy and data-intensive task has been greatly simplified with the support of the software that is made available at the GitHub repository as well as the raw data of several case studies.
