Desarrollo de una aplicación móvil multiplataforma para los clientes del sistema de Smart Lockers de la Corporación Wolf S.A

Abstract

The objective of this degree work is focused on the development of a multiplatform mobile application for the clients of the Smart Lockers system of Wolf Corporation S.A. by using the agile development methodology SCRUM. In the initial stage, we defined the functionalities of the application through meetings and interviews with the people responsible for the system, from which a product backlog was obtained with a total of 29 user stories and 8 technical stories that were distributed in 5 modules. As development technologies we utilized: TypeScript as the main programming language; React Native as the multiplatform mobile development framework; NestJS for the creation of the system server and PostgreSQL as the database management system. Furthermore, we utilized REST for communication with the server, Stripe as the monetary processing platform and JSON as the format for data exchange. The execution of the application development process was carried out for 18 weeks divided into 6 iterations (sprints) with a total of 360 estimated points. We evaluated the functionality of the application according to the ISO/IEC 25010 standard by measuring the quality characteristic Functional Suitability, through the sub-characteristics that comprise it. The measurement process was carried out utilizing the metrics defined in ISO/IEC 25023 standard, thus obtaining the following results: functional completeness 100%, functional correctness 94.3%, and functional appropriateness 100%. According to these values, we obtained a functional suitability of 98.1%, which suggests that the developed multiplatform mobile application presents a high degree of functionality, thus ensuring that it can meet the needs of the Smart Lockers system customers.
