Desenvolvimento e avaliação de uma solução SaaS multi-tenant para gestão do transporte universitário intermunicipal

Abstract

This study was conducted in the context of the intercity university transportation service operating between Campo Maior and Piripiri, in the state of Piauí. In the investigated setting, bookings, attendance confirmations, payment tracking, and trip organization re- lied on lists in messaging applications and scattered records, which hindered capacity control and the consolidation of operational information. The objective was to develop and evaluate a multi-tenant software-as-a-service solution to support the management of this service. The solution was implemented as a functional prototype comprising an application programming interface and a responsive web interface designed primarily for mobile devices; its architecture was organized in layers, inspired by Clean Archi- tecture principles, with business rules centralized on the server. Technical verification combined automated unit tests and an experimental cloud deployment, covering 13 functional modules, 93 interface endpoints, and 458 tests. The exploratory usability evaluation received 19 questionnaire responses: the quantitative analysis considered all 19 responses, while the qualitative analysis examined 18 sets of open-ended res- ponses. The core flows were implemented and verified, and item means ranged from 4.37 to 4.89 on a five-point Likert scale, providing initial favorable evidence of percei- ved usability and usefulness. The main limitation is the small, non-probabilistic sample and its imbalance across user profiles, which prevents generalization of the evaluation results.
