What is MOM?
Technical definition
Manufacturing Operations Management – the umbrella concept (defined in ISA-95 part 3) for managing production-related operations: production, quality, maintenance and inventory/logistics. MOM describes capabilities and activities – not a single system.
In brief
MOM is the operations domain. MES is one of the systems supporting it. Confusing the two usually means buying the wrong solution.
The Challenge
MOM is often reduced to the question “which MES should we buy?”. But production, quality, maintenance and logistics are connected in reality – and when each area buys its own system without a shared information model, you recreate the very silos digitalisation was supposed to remove. The quality deviation cannot be linked to the batch, the maintenance stop is invisible in production planning and the inventory balance lives a life of its own.
HubMind’s Methodology
We treat MOM as a capability map, not a product category. Using ISA-95 as the framework, we chart which activities you need to support – order management, traceability, quality follow-up, maintenance planning – and what information they share. Only then does it make sense to talk systems: MES, maintenance systems, LIMS or a combination.
The common denominator is always the information: the same equipment identities, the same material structure and the same naming convention across all four areas – anchored in your technical information architecture.
Warnings & Pitfalls
“MOM = MES”: Buying an MES does not solve maintenance, quality and logistics. Define the capabilities first, choose systems second.
The suite that solves everything: A vendor package covering all four areas rarely does all of them well. Evaluate per capability – and require open interfaces between the parts.
Four islands instead of one: Without a shared information model, each MOM area becomes its own project with its own identities – and integration becomes a permanent cost.
💡Our Recommendation
Map the capabilities: Use ISA-95 part 3 as an activity checklist – not as a system requirement list.
One information model for all four areas: Production, quality, maintenance and logistics must share identities and structure.
Prioritise by business value: Start with the capability that costs the most today – usually traceability or downtime follow-up.
Require openness: Every MOM system must be able to publish and consume data via standard interfaces.
FAQ
Is MOM a standard? MOM as a concept is defined in ISA-95 part 3, which describes activity models for production-related operations. It is a framework to base requirements on – not a certification.
Do we need a MOM platform? You need MOM capabilities. Whether they are delivered by one platform or several well-integrated systems is an architecture question – not a dogma.
How does MOM relate to the Purdue Model? MOM activities live mainly on level 3 of the Purdue Model – between automation and business systems.
