Manufacturing Execution Systems (MES) is a specialist class of production-oriented software that manages, monitors and synchronizes the execution of real-time, physical processes involved in transforming raw materials into intermediate and/or finished goods. These systems coordinate this execution of work orders with production scheduling and enterprise-level systems like ERP and product life cycle management (PLM). MES applications also provide feedback on process performance, and support component and material-level traceability, genealogy and integration with process history, where required. These capabilities extend from product/process design release (PLM) and work order release (ERP) through completion of the manufacturing process. Gartner’s view of the MES market does not include production automation software such as supervisory control and data acquisition (SCADA), distributed control systems (DCSs) or programmable logic controllers (PLCs).
