Desarrollo de una aplicación web para la gestión de inventario, venta y facturación electrónica en la empresa Induval utilizando el método de desarrollo para sistemas dinámicos.

Abstract

In this curricular integration work, a web application was developed for the management of inventory, sales, and electronic invoicing in the company INDUVAL, using DSDM (Dynamic Systems Development Method). In the pre-project phase, we identified the candidates; in the project life cycle phase, we analyzed the feasibility to develop the application. We analyzed the processes carried out in the business utilizing the interview technique, observation, and document review, obtaining 20 functional requirements, 10 technical requirements and 2 non-functional requirements. The application was developed in 8 timeboxes of 80 hours. The technologies used were Visual Studio Code as integrated development environment, the Angular framework under the TypeScript language, Bootstrap for template design and PostgreSQL as database manager. The applied architecture was MVC (Model, View, Controller) adapted to the framework, organized in modules formed by components, templates and services. In the post-project phase, the application was put into production, after that, the software quality was evaluated according to the ISO IEC 25010 standard. The capacity of operability, a characteristic included in usability, was measured by applying the SUS (System Usability Scale) questionnaire, obtaining a result of 89.4 points equivalent to excellent; we obtained a decrease in time of 99.86% for performance efficiency based on time behavior in the generation of product reports, 78.04% in sales registration, 99.44% in sales reports and 98.2% in purchase reports. It is concluded that the use of the web application reduces the time spent in these processes. It is recommended to develop a mobile version that facilitates the use of the application throughout the company.
