For an effective maintenance strategy, key performance indicators that reflect the performance, risks, costs, and sustainability of maintenance are essential.
Typical strategic metrics include:
- Technical Availability
- OEE or OEE Drivers
- Percentage of Unplanned Maintenance
- MTBF (Mean Time Between Failures)
- MTTR (Mean Time to Repair)
- Degree of Plan Fulfilment
- Maintenance costs per plant or production unit
- Budget Accuracy
- Proportion of Outsourced Services
- Spare Parts Availability and Inventory
- Capital Requirements for the Existing Plant Fleet
What matters is not the number of metrics, but a consistent metrics system that supports strategic decisions and highlights the value contributed by maintenance.
Technical availability, OEE drivers, the proportion of unplanned maintenance, the degree to which plans are met, and investment and budget accuracy are particularly relevant for strategic management.
