Preventive Maintenance Compliance
The percentage of scheduled preventive maintenance completed on time.
What Is Preventive Maintenance Compliance?
Preventive Maintenance (PM) Compliance measures what percentage of scheduled preventive maintenance — services due by date, mileage, or engine hours — is actually completed on time. It's the strongest lead indicator for breakdowns, MTBF, and long-term maintenance cost across the entire KPI set.
Formula
Schedule preventive maintenance by mileage or engine hours where possible, not calendar date alone — high-usage vehicles need more frequent service regardless of the date.
Why Preventive Maintenance Compliance Matters
Leading, Not Lagging
Unlike most fleet KPIs, PM Compliance predicts future breakdowns rather than reporting past ones.
Direct Line to MTBF
Fleets with high PM compliance consistently show higher MTBF and lower unplanned downtime.
Compliance & Liability
In many jurisdictions, documented preventive maintenance is also a legal and insurance requirement, not just an operational nicety.
Typical Benchmark
💡 What's a Good Number?
High-performing fleets typically target PM compliance above 90%. Below that, unplanned downtime and maintenance cost per km both tend to climb noticeably.
How to Improve Preventive Maintenance Compliance
- Automate scheduling by mileage and engine hours, not just calendar reminders
- Integrate DVIR inspection data so defects are caught between scheduled services
- Plan workshop capacity around the PM schedule, not just as work arrives
- Report compliance per vehicle and per depot to spot systemic gaps early
