What this term means in maintenance
A maintenance key performance indicator, or KPI, is a defined measure used to monitor whether maintenance processes and outcomes support business objectives.
Types of maintenance KPIs
KPIs may measure:
Outcomes
- Equipment availability
- Downtime
- Reliability
- Maintenance cost
- Safety or quality impact
Process performance
- PM compliance
- Schedule compliance
- Planned maintenance percentage
- Backlog age
- First-Time Fix Rate
- Emergency work percentage
Leading and lagging indicators
Leading indicators measure activities expected to influence future results, such as inspection completion.
Lagging indicators measure results already experienced, such as breakdown downtime.
Practical example
A plant reviews PM compliance, critical backlog, MTBF, MTTR, and downtime cost together. No single measure is used as the complete view of maintenance performance.
Good KPI design
A KPI should have:
- Clear definition
- Business purpose
- Owner
- Data source
- Calculation rule
- Frequency
- Target or review range
- Action when performance changes
Common mistake
Tracking many metrics without clear decisions or actions creates reporting work without management value.
