Manufacturing Execution

Manufacturing Execution is the operational process of running production on the shop floor: dispatching work orders, tracking work-in-process, recording labor and machine time, capturing as-built configurations, and reporting yield and downtime back to engineering and ERP. It is where the digital plan turns into physical product.

Scope

The process is typically supported by a Manufacturing Execution System (MES) integrated with PLM (for the released MBOM, work instructions, and routings) and with ERP (for orders and inventory). ISA-95 defines the canonical functional layering and PLM↔MES↔ERP information flows. Closing the loop back to PLM enables As-Built configuration accountability and quality root-cause analysis.
