The aim of this article is to describe the proposal for an agile methodology focused on user requirements and its implementation in the System of Integral Administration of Human Resources (SAIRH). This methodology consists of a pre-phase of requirements that can be implemented to an agile methodology, in addition to a cycle for change requests that is incorporated into the cycle of the methodology used, the pre-phase consists of 5 stages: collection, analysis, prototyping, negotiation and the initial requirements report. The change request cycle includes 4 stages: change request, analysis, negotiation, adding the change to the requirements report. The implementation is carried out in the SAIRH where the XP methodology with MVC is used and both the pre-phase of requirements and the change request cycle are included, at the end of this work the impact that the use of this methodology has on the development time of the system is analyzed.
