A Manufacturing Execution System (MES) acts as a communication bridge between manufacturing planning (MRP) and plant floor operations, enabling real-time management of manufacturing processes and performance. Unlike basic data collection sensors, MES offers a comprehensive framework that includes quality management, task assignment, and performance statistics. The document focuses on the role of MES in enhancing manufacturing efficiency, particularly through tools like MRPeasy, which facilitates real-time reporting with a user-friendly interface.
