What Is the Difference Between CMMS, FSM, and a Service Infrastructure?
CMMS manages maintenance tasks internally. FSM coordinates field technicians. A service infrastructure like Transaction-Network connects OEM, operator, and supplier in one shared service process - vendor-independent, across company boundaries. This is a fundamentally different approach.
Anyone searching for industrial service software runs into three terms: CMMS, FSM, and service infrastructure. They sound similar, but they solve fundamentally different problems.
What is a CMMS?
CMMS stands for Computerized Maintenance Management System. It is a tool for internal maintenance - typically used by the operator of a plant. A CMMS manages maintenance schedules, work orders, spare parts inventory, and maintenance histories.
What a CMMS cannot do: it does not communicate with the machine builder. It does not trigger orders. It does not coordinate external service partners. It stops at the company boundary.
Typical systems: SAP PM, IBM Maximo, Infor EAM, Ultimo.
What is an FSM system?
FSM stands for Field Service Management. It is a tool for companies that deploy field technicians - typically the machine builder (OEM). An FSM system schedules jobs, coordinates technicians, documents service reports, and optimizes route planning.
What an FSM system cannot do: it does not see the operator's machine data. It does not automatically integrate spare parts orders. It does not connect operator, OEM, and supplier in one shared system.
Typical systems: Salesforce Field Service, ServiceMax, Microsoft Dynamics 365 Field Service.
What is a service infrastructure?
A service infrastructure is a different category - it does not solve the problem of a single party, but the problem between the parties.
Transaction-Network is the service infrastructure for machine building. OEM, operator, and supplier are connected within it - vendor-independent, without media gaps, without manual coordination. When a machine reports an issue, everyone involved sees it immediately - and acts within the same system.
That is the structural difference: CMMS and FSM are tools for one side. A service infrastructure is the shared foundation for every side.
Comparison at a glance
| Criterion | CMMS | FSM | Service Infrastructure (TN) |
|---|---|---|---|
| For whom? | Operator | OEM / service provider | OEM + operator + supplier |
| Focus | Internal maintenance | Field service coordination | Cross-company service |
| Machine data | Internal | Limited | Live, machine-bound |
| Vendor-independent? | No | No | Yes |
| Spare parts ordering | Manual | Not integrated | Automated |
| Media gaps | Low internally | High externally | None |
| Scaling | With headcount | With headcount | Structural |
Why the distinction matters
Many machine builders and manufacturers start with CMMS or FSM - and hit a limit after some time. Downtimes still occur because coordination between operator and OEM runs by phone and email. Spare parts arrive too late because no system automatically triggers demand. Service only grows with more headcount, because the processes are not structurally connected.
This is not a failure of CMMS or FSM systems - they solve their problem well. It is a structural problem: industrial service is a problem across multiple companies. CMMS and FSM are tools for just one of them.
Service only works when everyone collaborates - in a network. The Industrial Service Network.
Frequently Asked Questions
Can I keep using CMMS or FSM if I adopt Transaction-Network?
Yes. Transaction-Network does not replace existing systems - it connects them. Existing ERP, CMMS, or FSM systems are connected via dataX, Transaction-Network's integration layer. No system change, no data loss.
Who benefits from a service infrastructure - OEM or operator?
Both - that is the core idea. An OEM benefits from structured service revenue, relieved service teams, and self-service for operators. An operator benefits from fewer downtimes, faster response times, and transparency across every machine - regardless of vendor.
What distinguishes Transaction-Network from a digital spare parts marketplace?
A marketplace is a channel for orders. Transaction-Network is the infrastructure that automatically detects demand, identifies the right supplier, and triggers the order - without manual intervention. Not another portal, but the trigger behind it.
How many machines need to be connected for it to be worthwhile?
Getting started is possible with a single machine or production line. The benefit grows with the number of connected machines and manufacturers - because the network makes every new participant more valuable. A pilot project goes live in 4-6 weeks.
