Difference between MES and MOM?

The terms Manufacturing Execution System (MES) and Manufacturing Operations Management (MOM) are often used interchangeably, and each defines a different functional area for every manufacturing expert.

Some believe that they are synonymous and/or can be used interchangeably.
Some believe that MES is a subset of MOM.
Some believe we need to choose one of them.
The majority have no idea.

We will use the term Manufacturing Operations Management (MOM) to encompass the ISA-95 Level 3 architecture and functionality, as shown in the simplified diagram in the graphic. This also includes extensions or variations within the ISA-95 model.

MOM is also a more comprehensive solution that drives other related operations such as warehouse, shipping, quality, and labor. In addition, a complete MOM solution can provide a type of visibility for supply chain operations and “big data” production, serving as decision support in the form of production forecasting.

Thanks to the hardware capability of Trex, it can go down to Level 0 by receiving and processing data like a PLC when needed, without requiring any additional device, as it can receive signals directly from machine sensors. When considering software solutions such as quality maintenance modules, it is a product that goes beyond the boundaries of MES and falls within the boundaries of MOM.
