Análisis, requisitos funcionales y diseño UML de un sistma de nómina

Abstract

This project presents the analysis, definition of functional requirements, and UML design of a payroll information system aimed at improving the processes of J&J Instalaciones, a Bogotá-based company dedicated to the design and manufacturing of custom furniture. The main objective is to optimize payroll management, reduce payment errors, ensure regulatory compliance, and increase operational efficiency. The research begins with a diagnosis of the company’s current situation, identifying issues such as the lack of a specialized system, manual handling of information, errors in payroll calculations, and difficulties in meeting legal obligations. Based on this, technical solutions are proposed and translated into a structured system model documented in accordance with international standards. To achieve this, a methodology divided into three phases was applied. The first phase focuses on designing the conceptual data model, identifying the system’s actors, entities, and relationships. The second phase involves the detailed documentation of functional requirements for each key system module, including employee management, incidents, disabilities, and vacations. The third phase graphically represents the processes using use case diagrams, sequence diagrams, and activity diagrams, all modeled in UML and aligned with ISO/IEC standards. The result is a clear, verifiable, and traceable model that enables a safer and more effective technical implementation, minimizing ambiguity and errors. As both an academic and practical contribution, this work provides a solid methodology that can be replicated in similar projects within the field of software engineering applied to administrative systems.
