CMMS

CMMS (Computerised Maintenance Management System) studies the system category for maintenance scheduling, work-order management and maintenance-history recording. It is functionally narrower than CAFM: focused on the maintenance process itself, not on space, contract or service broadly.

For technical management, CMMS is often the first system investment, and the quality of the maintenance history recorded in it determines whether later maintenance-engineering analysis (failure behaviour, RCM) is possible.

• Is the failure cause recorded consistently, or only the fix?
• Is there a distinction between CMMS as a standalone system and a CMMS module within a broader CAFM/IWMS platform, and was that a deliberate choice?

• Maintenance-engineering literature on CMMS data quality as a precondition for RCM/predictive maintenance.

• A CMMS without disciplined entry of failure cause never produces usable failure analysis, however advanced the system.

• Maintenance & Asset Care

• Work-order recording and failure analysis

• In-house (retained) delivery organisation

  In-house technical staff can enforce input discipline more effectively than an externally contracted crew without system training.

• EN 13306 (maintenance terminology) as the conceptual basis for CMMS data fields.

The standards section arrives in Part 7.

• CMMS data used for benchmarking between sites without checking whether input discipline is equal everywhere.

Automatic classification of failure cause via text analysis of free-text fields is being explored to compensate for weak input discipline, but reliability with technical jargon and multilingual input remains limited.
