Industrial preventive maintenance is the same discipline as any site's, a schedule of tasks against a register, with three things that change on an industrial scale: the register is large and arranged by line, the triggers are meters rather than dates, and the tasks carry isolation and permit steps that are the law. Total preventive maintenance, usually called total productive maintenance, is the plant-wide version where operators, maintenance and engineering share the work. This page sets out what changes at industrial scale and what the total version adds beyond the schedule.
What changes at industrial scale
Hundreds or thousands of assets in a hierarchy, so a work order against a motor reports to a line. Run-hour and cycle-count triggers on the production equipment, because usage varies by line and shift. Isolation, lockout and permit-to-work steps on most tasks, written into the procedure because the hazardous-energy rules require them. Shift handover of open work. And a planner whose job is levelling the schedule and preparing the big jobs, which a small site's supervisor does in passing.
The schedule on an industrial site
Daily operator checks on every machine. Weekly technician inspections by area. Monthly and run-hour services on the production equipment. Quarterly and annual tasks that need a line down, planned weeks ahead with parts and contractors. Statutory tests on pressure systems, lifting gear and safety devices. The planner levels it, the CMMS raises it, and the reactive queue is read at every shift change. This site's worked example, 180 assets and 60 preventive jobs, is the smallest end of this shape.
What total preventive maintenance adds
In total productive maintenance the operators own the daily care of their machines, the maintenance team owns the planned and corrective work, and engineering owns removing the failure modes that repeat. Overall equipment effectiveness is the plant's measure. What it adds to a schedule is the people: a machine seen every shift by the operator who runs it fails less than one seen monthly by a technician, and a failure mode designed out fails never. What it needs is the same record, because operator tasks and engineering changes both have to show in the history.
The record at scale
An industrial site cannot run its schedule from memory, and the CMMS is not optional at this scale. What is still optional is whether findings are recorded and read: a plant with a thousand assets and empty findings fields has the software and not the programme. The reactive share by line, the schedule compliance by area, and the recurring findings are the three figures the plant manager reads, and all three come from work orders closed honestly at the machine.
Questions people ask about industrial preventive maintenance
Is total preventive maintenance the same as TPM?
Yes; TPM is total productive maintenance, and the preventive version of the phrase means the same programme. The word total refers to everyone in the plant taking part.
Does industrial preventive maintenance need a planner?
Above a few hundred assets, yes. The planner levels the load, prepares the shutdown tasks and keeps the schedule honest; without one the supervisor does it badly in spare moments.
Where do I start on an industrial site with no programme?
With the register by line, the daily operator checks, and the reactive work orders recorded with findings. The schedule is built from the failures the history shows, one line at a time.
