The present work of degree shows the development of the system of requisitions Cobra (REQUICOBRA) that automates the process of request of resources within the company. This document aims to show the engineering process performed to solve the problem found in the company with analysis, design, development and testing phases. In the first instance, we seek to contextualize the reader with a general description of the problem to be solved within the degree work. Subsequently, the objectives set out that show the expectations and goals to be fulfilled within the project are shown. Finally, we explain the work methodologies that will ensure the fulfillment of the objectives set for the work of degree. On the other hand, the analysis and design stages are shown where the relevant information of the business process within the company is collected. Based on this information, the requirements and use cases architecturally significant within the degree work are raised. Subsequently, the design of the system architecture is carried out based on the information obtained in the analysis phase. As for the development of the solution, it seeks to show in broad outline the process of building the software, describing the business process, modeling the system and the main screens of the system. Additionally, briefly explains the test process and the results obtained from them. Finally, we find the conclusions of the degree work and the proposed future work.
