Desarrollo del sistema web para el control de inventarios, ventas, facturación y publicidad del Taller de Aluminio y Vidrio “López” aplicando la metodología Lean Software Development.

Abstract

The main purpose of this research was to develop a web system to the inventories control, sales, billing, and advertising of “López” aluminium and glass workshop. Both, the interview and the observation were techniques of great importance in order to identify the problems and needs of this entity. In order to develop this web system the agile LEAN SOFTWARE DEVELOPMENT methodology was used. This methodology provides processes in which the standards and rules making the project undertaken becomes more likely to succeed are established. This methodology is based on principles that establish optimal guidelines for the development of software. One of the important aspects for software creation are the technologies of development to be used. JAVA, EDGRID Java Script, HTML, CSS, MYSQL; IDE NETBEANS 8.2 have been used in this project. When applying the agile methodology, forty-one functional and non-functional requirements were obtained and forty-five diagrams were created. From the total of tests conducted, a percentage of 86 % were successful while in the evaluation of the system it was found that 92% of users agreed that the loss of information is avoided, an 83% affirm that it avoids the delay in some processes. Regarding to the sub-characteristics of functionality of the web system, users have evaluated it under the following indicators; 91.67% are completely satisfied with the system, 5.56% are satisfied, while only 2.77% are unsatisfied. In addition to this, three of the four functional parameters have been accomplished, which is equivalent to 75%. All these results make possible to conclude that the system meets the needs of users in a very high percentage and it is functional for them in a 97.23%. It is recommended to use the agile methodology to optimize resources during development.
