Key takeaways
Short answer: Autonomous and preventive maintenance are two complementary pillars of TPM that divide maintenance work between operators and technicians. Autonomous maintenance puts basic, routine care — cleaning, inspection, lubrication, minor adjustment — in the hands of the operators who run the equipment, so they own its condition and catch problems early. Preventive maintenance is the scheduled, skilled servicing done by the maintenance team at set intervals. One builds operator ownership and early detection; the other delivers planned, technical intervention. For the broader strategy choice, see preventive vs predictive maintenance.
Autonomous maintenance — a core pillar of TPM — shifts basic, routine equipment care to the operators who run the machines every day. Rather than treating operators as mere users who hand off all maintenance to a separate team, autonomous maintenance trains and empowers them to clean, inspect, lubricate, tighten, and watch their own equipment, catching abnormalities early. Its philosophy is ownership: the person closest to the machine, who sees and hears it constantly, is best placed to notice the small signs — a leak, a loose bolt, an unusual noise, a developing wear pattern — before they become breakdowns. Autonomous maintenance is as much cultural as technical: it builds a sense of responsibility for equipment condition on the floor, freeing skilled technicians to focus on more complex work while operators handle the basics and act as the early-warning system.
Preventive maintenance is scheduled servicing performed by the maintenance team at predetermined intervals — by time or usage — to prevent failures before they happen. It is the planned, skilled side of maintenance: technicians carrying out defined tasks (replacing wear parts, deeper inspections, calibrations, overhauls) on a schedule, regardless of the equipment's apparent condition that day. Preventive maintenance requires the tools, training, and planning of a maintenance function; it is not the routine daily care of autonomous maintenance but the deeper, technical intervention that keeps equipment fundamentally sound. Where autonomous maintenance is continuous and operator-driven, preventive maintenance is periodic and technician-driven — the scheduled backbone that handles the work beyond an operator's basic care.
The distinction is who does what, and when. Autonomous maintenance is operator care: continuous, routine, basic tasks done by the people running the equipment, focused on cleaning, inspection, and early detection. Preventive maintenance is scheduled servicing: periodic, skilled, deeper work done by technicians on a plan. They are not competing approaches but a division of labour — operators handle the frequent basics and act as eyes and ears, technicians handle the scheduled technical work. The relationship matters: autonomous maintenance often catches the small issues that, left alone, would become the breakdowns preventive maintenance and reactive repairs exist to handle. Done together, they form a layered defence — daily operator care on top, scheduled technical servicing beneath — rather than either group trying to do it all.
Take a packaging machine. Under autonomous maintenance, the operator starts each shift with a short routine: wipe down the machine, check oil levels, listen for unusual sounds, confirm guards and sensors, and tighten anything loose — and crucially, report anything abnormal. One morning the operator notices a small oil leak and a faint new vibration, and logs them. That early catch is autonomous maintenance doing its job. Preventive maintenance then operates on its schedule: every quarter, a technician performs the deeper service — replacing the wear parts, doing a thorough inspection, and, prompted by the operator's leak report, investigating and fixing the seal before it fails. The operator's daily care caught the early sign; the technician's scheduled work handled the skilled repair. Neither alone would have been as effective as the two layered together.
In TPM, autonomous and preventive maintenance are distinct pillars designed to reinforce each other. Autonomous maintenance builds the operator ownership and daily care that keeps equipment clean, lubricated, and watched — preventing the accelerated deterioration that comes from neglect and providing early warning of developing problems. Preventive maintenance provides the scheduled, skilled intervention that operators are not equipped to do. The synergy is real: operators performing basic care reduce the load of small failures, freeing the maintenance team to do planned work well rather than firefighting; and the operators' early reports make the technicians' scheduled work better targeted. A plant that does only preventive maintenance misses the daily care and early detection; one that does only autonomous maintenance lacks the skilled scheduled backbone. TPM deliberately uses both.
Both pillars raise the availability factor of OEE, from different angles. Autonomous maintenance prevents the slow deterioration and catches the early-stage problems that would otherwise become breakdowns, while preventive maintenance converts potential failures into planned, scheduled work — together shifting the balance from unplanned to planned downtime, the single biggest availability lever. Both improve reliability by raising effective MTBF. And because autonomous maintenance keeps equipment clean and correctly set, it also protects the performance and quality factors — a well-cared-for machine runs closer to rate with fewer defects. As pillars of TPM, whose headline metric is OEE, they are explicitly aimed at the six big losses.
Fabrico connects both kinds of maintenance to the OEE they protect. It captures the downtime and reliability data that shows whether autonomous and preventive maintenance are actually working — whether early operator catches and scheduled servicing are shifting losses from unplanned to planned and lifting availability. By giving operators and technicians a shared view of which losses are biggest, it focuses the daily care and the scheduled work on the equipment and failure modes that matter most, and confirms the gains.

Autonomous maintenance has operators perform basic care — cleaning, inspection, lubrication, minor adjustment — on their own equipment. Preventive maintenance is scheduled servicing done by technicians at set intervals. Autonomous maintenance builds operator ownership and early detection; preventive maintenance delivers planned, skilled intervention.
Yes. Autonomous maintenance is a core pillar of Total Productive Maintenance, alongside planned (preventive) maintenance. TPM uses both — operators handle daily basic care and early detection while technicians perform the deeper scheduled work.
Operators perform routine care on their own equipment: cleaning, inspecting, lubricating, tightening, checking levels and sensors, and reporting abnormalities. The goal is to prevent deterioration from neglect and catch developing problems early, before they become breakdowns.
No. It handles basic, routine care and early detection, freeing technicians to focus on skilled, scheduled, and complex work. Preventive maintenance and deeper repairs still require the maintenance team's tools, training, and planning.
Both raise availability by shifting downtime from unplanned to planned — autonomous maintenance through early detection and daily care, preventive maintenance through scheduled servicing. Autonomous care also protects performance and quality by keeping equipment clean and correctly set.
