Abstract
Introduction: PWAs are web applications considered as a natural evolution of traditional web applications, capable of integrating into mobile devices and performing tasks that generally only native applications could perform. Usability and portability correspond to two parameters of the quality model, usability refers to the ease with which people can use a computer tool. It is based on three parameters: efficiency, effectiveness and satisfaction. On the other hand, portability is defined as the effort to transfer the application to another operating system, device and platform. Objective. To measure the usability and portability parameters in the Traditional Web Application and the Progressive Web Application (PWA), created for a home delivery service, through the use of the questionnaire called System Usability Scale (SUS) and the use of general formulas in order to obtain information and perform a comparative analysis of the results. Methodology. The present research is defined as comparative descriptive, it is part of the quantitative paradigm; it uses the survey and formulas in the measurement process, as well as the Iterative - Incremental model for the development of web applications. The population consisted of 25 users to whom the SUS usability questionnaire validated by the scientific community that studies usability issues was applied. Results. The results reveal that the Usability in the traditional web application is 80.3, while the PWA presents an overall average result of 84.02; in portability the values are between 75% and 85.35% respectively. Conclusions. It is concluded that in terms of usability and portability the values favor the PWA, a result that is mainly attributed to the improvement characteristics that this technology presents in the development of web applications.
