MOM
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 defines what to build; MOM defines how to build it and verifies it was built correctly. The PLM-MOM interface (passing the mBOM and work instructions downstream, passing as-built records upstream) is where the digital thread from design to production closes. Without MOM integration, PLM-defined changes do not reach the shop floor, and as-built data does not flow back to engineering and quality.
