Manufacturing operations management (MOM)

Also known as: MOM, Level 3 operations

German: Manufacturing Operations Management (MOM)

In ISA-95 / IEC 62264, manufacturing operations management (MOM) is the set of Level 3 activities that coordinate personnel, equipment, material and energy to convert raw materials or parts into products. It is divided into production, maintenance, quality and inventory operations management.

In one sentence

In ISA-95, manufacturing operations management (MOM) covers Level 3 activities for production, maintenance, quality and inventory operations.

Example

The plant's MOM landscape consists of an MES for production and quality, a maintenance management system and a warehouse management system, all integrated with the ERP.

How it applies

  • Engineering: IEC 62264-3 describes a generic activity model for each category: resource management, definition management, detailed scheduling, dispatching, execution management, data collection, tracking and performance analysis.
  • Project management: Mapping the four categories and their activities to systems reveals gaps and overlaps before software is selected.
  • Operation: MOM connects business orders with the actual production on the shop floor and reports results back.
  • Documentation: System descriptions should state which MOM activities a system covers. Using the activity names from the standard helps readers compare products and specifications.

MOM vs. MES

A Manufacturing execution system (MES) is a software product or system. MOM is the functional scope defined by ISA-95. One MES rarely covers all of MOM, and several systems together often do.
