In many factories, the relationship between production and maintenance looks like this: production runs machines until they break, then calls maintenance; maintenance fixes them as fast as possible and goes back to waiting for the next call. Nobody owns the condition of the machine between breakdowns. Total Productive Maintenance (TPM) changes that relationship by making equipment care everyone's responsibility, with the goal of zero breakdowns, zero defects and zero accidents.
The eight pillars of TPM
- Autonomous maintenance: operators clean, inspect, lubricate and tighten their machines.
- Planned maintenance: maintenance teams schedule preventive and predictive work based on data.
- Focused improvement: cross-functional teams eliminate specific losses.
- Quality maintenance: keeping equipment conditions that guarantee good quality.
- Early equipment management: designing and buying equipment that is easier to maintain.
- Training and education: building operator and maintenance skills.
- Safety, health and environment: eliminating accidents and hazards.
- TPM in administration: applying the same thinking to office processes.
All eight matter in a mature programme, but small and mid-sized factories get most of the early benefit from the first three.
Autonomous maintenance
Operators are closest to the machine and notice changes first — a new noise, a leak, a loose guard. Autonomous maintenance turns that knowledge into routine. It typically progresses through steps: initial deep cleaning to reveal hidden problems, eliminating sources of contamination and hard-to-reach areas, creating cleaning and lubrication standards, general inspection training, and finally autonomous inspection with operators owning daily checks.
Daily operator checklists usually take five to ten minutes: clean key areas, check oil levels, listen for noises, check for leaks, verify guards and safety devices. Any abnormality is tagged and reported.
Abnormality tags
When operators find a problem they can't fix themselves, they raise an abnormality tag — traditionally a physical red or white tag on the machine. The tag records what was found, where and when, and stays until the problem is fixed. The number of open tags, and how quickly they are closed, is one of the clearest measures of TPM health. If tags stay open for weeks, operators stop raising them.
Planned maintenance
Maintenance teams take on the work that needs specialist skills: preventive maintenance at the right intervals, condition-based inspections, overhauls and improvements. With operators handling basic care, maintenance can shift time from firefighting to planned work. Breakdown records and MTBF data help set intervals and identify components that fail repeatedly. See preventive maintenance software.
Focused improvement
Small teams — operator, maintenance technician, process engineer — target a specific loss on a specific machine: a recurring breakdown, long setups, a chronic quality defect. They use data, root-cause analysis and trials to fix it, then standardise the solution. See the six big losses.
Starting TPM: the model machine approach
- Choose a model machine: important, visible and with known problems — but not the most complex.
- Measure the baseline: OEE, breakdowns, MTBF and MTTR for a few weeks.
- Deep clean with the team: operators, maintenance and supervisors together, tagging every abnormality found.
- Fix the tags: quickly and visibly, so the team sees results.
- Create standards: cleaning, lubrication and inspection checklists with photos.
- Train and hand over: operators own daily checks; maintenance owns the PM plan.
- Review results: compare OEE and breakdowns with the baseline, and share the story.
- Expand: roll out to the next machines using what you learnt.
An example: the model machine
An auto components plant chose a CNC turning centre with frequent coolant and chip conveyor problems as its model machine. The initial clean revealed more than thirty abnormalities — leaks, loose fasteners, blocked filters, missing covers. Most were fixed within two weeks. Operators took on a seven-minute daily checklist; maintenance revised the PM plan for the conveyor and coolant system. Over the next three months, breakdown hours on the machine fell substantially and coolant-related quality issues almost disappeared. The success made it much easier to extend TPM to the rest of the line.
Measuring TPM progress
- OEE and its components per machine.
- Breakdown count and hours; MTBF and MTTR.
- Operator checklist completion rate.
- Abnormality tags raised and closed, and average time to close.
- PM compliance — planned tasks completed on time.
Common mistakes
- Treating TPM as a cleaning campaign that fades after a month.
- Giving operators checklists without training or explaining why.
- Leaving abnormality tags open for weeks.
- Starting across the whole factory instead of on a model machine.
- No measurement, so nobody can show the results.
How software helps
Paper checklists and tag boards work at first but become hard to track across many machines. Maintenance software digitises operator checklists, abnormality tags with photos, PM schedules, breakdown records and spare parts, while OEE tracking shows the effect on machine performance. See maintenance management software (CMMS).

TPM and the role of maintenance teams
TPM sometimes worries maintenance teams, who fear that handing tasks to operators reduces their role. In practice, the opposite happens. When operators handle cleaning, lubrication and basic checks, maintenance technicians spend less time on avoidable breakdowns and more on skilled work: improving reliability, refining PM plans, training operators and solving chronic problems. Involving maintenance in designing operator checklists from the start builds ownership on both sides.
Getting started
Pick one model machine, measure its baseline for a month and run a deep-clean day with operators and maintenance together. Fix the tags quickly, introduce a short daily checklist and review results weekly. Once the model machine shows clear improvement, use it as a training ground for the next machines.
Frequently asked questions
What does TPM aim to achieve?
Zero breakdowns, zero defects and zero accidents, by making operators and maintenance teams jointly responsible for equipment condition.
Do we need to implement all eight pillars?
No. Most SMEs start with autonomous maintenance, planned maintenance and focused improvement on a model machine, then expand.
Will operators accept maintenance tasks?
When tasks are simple, well-trained and clearly linked to fewer breakdowns, most operators accept them — especially when abnormalities they report are fixed quickly.
How long does TPM take?
Visible results on a model machine often come within a few months. Spreading TPM across a factory is a multi-year journey.
How does software support TPM?
By digitising operator checklists, abnormality tags, PM schedules, breakdown records and OEE, so progress is visible and nothing is forgotten.
