Operational excellence is fundamental in the management of industrial organizations, focusing on continuous improvement and efficiency to achieve a sustainable competitive advantage. Key performance indicators (KPIs) such as Order Cycle Time (OCT), On-Time Delivery (OTD), and Overall Equipment Effectiveness (OEE) are essential for measuring this excellence. Understanding these concepts is a crucial skill for engineering students, although it is not always effectively conveyed through traditional educational techniques. In this study, an ERP system simulator applied to an automobile assembly plant was used as an innovative educational tool. The simulator allowed engineering students to identify production risks, improve quality and efficiency, and apply lean manufacturing tools in real-time. This practical methodology fostered the understanding and application of the Funnel Theorem, facilitating process analysis and improvement. At the end of the project, students demonstrated a deeper understanding of production and operational efficiency concepts, reporting greater satisfaction and motivation. The implementation of the simulator significantly improved the teaching-learning process, effectively preparing students for future professional challenges, and ensuring they master the necessary concepts and practices to achieve operational excellence.
