What is MES?

A manufacturing execution system (MES) is defined as the layer that integrates business systems with the plants control systems and is generally referred to as integration from the “shop floor to the top floor”.

The Manufacturing Enterprise Solutions Association MESA International, define a MES as follows:

“A Manufacturing Execution System (MES) is a dynamic information system that drives effective execution of manufacturing operations. Using current and accurate data, MES guides, triggers and reports on plant activities as events occur. The MES set of functions manages production operations from point of order release into manufacturing to point of product delivery into finished goods. MES provides mission critical information about production activities to others across the organization and supply chain via bi-directional communication.”
