A fleet maintenance program looks like a building's programme with different equipment and is structurally different in three ways that change how it has to be run. The interval is driven by distance or engine hours rather than the calendar. The asset is somewhere else when it becomes due. And there is a person with the vehicle every day who notices things before any schedule would, which is a channel a building programme simply does not have. Programmes that ignore the third one waste their best input.
Distance drives it, so the due date is a projection
A vehicle due at a mileage figure has a due date only in the sense that it will probably reach it around then. That means the schedule is a forecast from a rate, and vehicles doing very different work drift apart quickly. A programme that fixes vehicle services to calendar dates will over-service the low-mileage vehicles and be late on the high-mileage ones every single year.
The asset moves, so the window is availability
Servicing a vehicle takes it off the road, so the constraint is operational rather than technical. Practical programmes cluster services into windows when the vehicle is least needed, accept a tolerance around the exact figure, and plan for the vehicle being away rather than treating each service as a surprise.
The driver is the sensor you already have
A daily walk-round and a simple way to report a defect catches more, sooner, than any interval will. What decides whether it works is what happens to the report: if a defect raised in the morning visibly becomes a job, drivers keep reporting; if it disappears, reporting stops within weeks and the channel is gone. Requirements for driver checks and vehicle records vary by jurisdiction and operation and are a matter for your own compliance adviser.
Questions people ask about fleet maintenance program
Should fleet maintenance be scheduled by miles or by time?
By whichever comes first, expressed as one rule. Time still matters for fluids and seasonal items on a vehicle that barely moves, and distance matters for everything on one that does.
How do we collect mileage without telematics?
Read it at every service and at fuelling, and let the programme project a rate. Telematics improves the precision; it is not what makes the programme work.
Where do driver defect reports go?
Into the same record as the planned work, against the vehicle. Keeping them in a separate book is how a repeated report goes unnoticed for months.
