Desarrollo e implementación de un sistema web para la automatización de gestión de procesos BC3-System, utilizando criterios de funcionalidad y usabilidad.

Abstract

In this titling work, the web system BC3 System was developed for the process management of a project carried out by BC3 Ingenieros S.A. since its processes are carried out in an unordered manner and with a delay in its tasks. Therefore, the development of the system was proposed applying the Scrum methodology according to its three phases: in the planning phase, a total of 81 functional requirements were defined; and two non functional. The system was developed in 18 sprints each has 80 hours of work. In the design phase the PHP programming language was established with the Symfony 4 Framework, the architecture of the Model View Controller (MVC) Framework, together with the MySQL database manager and Bootstrap for the design of templates; in the development phase, each of the system’s requirements was codified. Subsequently, the quality of the system was evaluated using the usability and functionality criteria of ISO/IEC 9126. The usability was assessed applying the USE Questionnaire methodology (utility, ease of use and learning, satisfaction) applied to 32 workers of the company that represent the total sample, the results were evaluated through a descriptive and inferential analysis made to each aspect of the survey. The functionality was assessed qualitatively in the elements of interoperability and security through the study of cases, describing the scenarios connecting to two MySQL and PostgreSQL database. Finally, it was concluded that the system is useful, easy to use and learn, satisfying the needs of the user according to the data perceived by the respondents and functional by the established scenarios since they were correctly fulfilled. The use of the user manual is recommended for better management of the system.
