Manufacturing Operations Management
Manufacturing Operations Management (MOM) is the layer of software between ERP and the shop floor that manages, coordinates, and optimizes manufacturing execution. It encompasses MES (Manufacturing Execution Systems), quality management, production scheduling, performance analytics, and maintenance management. MOM is a broader term than MES — MES is the execution layer, while MOM includes the planning, analytics, and quality management that surrounds it. Siemens Opcenter, Rockwell FactoryTalk, and Dassault DELMIA Apriso are prominent MOM platforms.
Why it matters
PLM hands its mBOM and routing into the manufacturing world; what receives that handoff varies by enterprise. In a single-plant shop, MES is the receiver. In a multi-plant manufacturer, MOM is the receiver and MES is one execution layer underneath. Knowing which architecture is in place determines where engineering changes land, who tracks the as-built record, and what feedback loop, if any, returns to PLM from the line.
