MES
Operations management: orders, genealogy, quality, OEE.
Manufacturing execution systems manage shop-floor operations: scheduling, dispatch, genealogy, quality, and OEE. They sit between ERP (Level 4) and control (Levels 0–2), attaching production context — lots, orders, serial numbers — to raw process data.
