Maintenance & safety
What is Total Productive Maintenance (TPM)?
· Updated · 4 min read
In a perfect world, machines would never break down, assembly lines would never stop, superior products without defects would be produced, product quotas would always be met, and products would be picked up and delivered on time. But, unfortunately, it’s not a perfect world. Sometimes things happen that throw production off schedule. This is where Total Productive Maintenance (TPM) comes in. TPM is the idea that looking after equipment is everyone’s job, not only the maintenance team’s: operators clean, inspect and care for their own workstations to ensure safety and quality during production, and maintenance specialists focus on the work that needs their skills.
What is TPM and how is it connected to Lean manufacturing?
The Total Productive Maintenance approach was developed in Japan and widely promoted by the Japan Institute of Plant Maintenance (JIPM). Nippondenso, a supplier of automotive components to Toyota, is generally credited as the first company to apply it plant-wide. Toyota and other Japanese manufacturers followed. TPM is a natural extension of Lean manufacturing because it is also aimed at eliminating waste.
Total Productive Maintenance engages all employees in the effort to eliminate waste by improving the operation, reliability, and efficiency of equipment used to manufacture products. TPM moves routine maintenance tasks, such as cleaning, inspection and lubrication, from the maintenance team to the operators who actually work with the equipment. This puts the people most familiar with the equipment in charge of keeping it in good condition, while the maintenance team concentrates on planned maintenance and repairs. When implemented properly, TPM tries to achieve the following goals:
- No equipment failures
- No stops
- Faster and smoother production
- No defects
- Lower operating costs
- A safer working environment
Benefits of total productive maintenance
1. Less unplanned maintenance with TPM
With carefully planned and scheduled maintenance, equipment is well maintained. TPM also gives all plant personnel ownership of their machines and makes preventive maintenance part of everyone’s routine. Since TPM makes maintenance personal, assets are better cared for.
2. Reduced equipment downtime
More planned maintenance means fewer failures. By implementing proactive maintenance activities, downtime events are minimised.
3. Total productive maintenance lowers manufacturing costs
As overall equipment effectiveness (OEE) increases, production costs come down. Higher productivity leads to higher profits and less spending on stoppages and repairs.
4. Strengthened workplace safety
Because TPM is built on the 5S foundation, the workplace is systematically organised and cleaned. The steps in the 5S method—sort, straighten, shine, standardise, and sustain—uncover underlying problems and challenges to maintaining the work environment.
Autonomous maintenance: operators own the basics
Autonomous maintenance is the TPM pillar most people mean when they say operators own their machines. Operators do the daily basics—cleaning, inspection, lubrication and tightening—and report anything abnormal. Cleaning is inspection: wiping down a machine is when you notice the oil leak, the loose bolt or the worn belt.
For it to work, operators need:
- Standard instructions for each task. What to clean, which points to lubricate, with what and how much, and what “good” looks like. Photos and short videos work better than text.
- Short checklists at the machine, done at fixed times, so the basics don’t depend on memory.
- Training before responsibility. Maintenance trains operators on each task and confirms they can do it before they work alone.
- Clear limits. Which problems the operator fixes, and which they report to maintenance.
One-point lessons are a practical format for these standards: one task or one abnormality per page or video, easy to read at the machine.
Conclusion
TPM is not a maintenance department project. It changes who does what: operators take on the daily care of their equipment, and maintenance specialists spend their time on planned work and improvements. Start with one machine. Clean it thoroughly, fix what you find, write the cleaning and inspection standards, train the operators and measure OEE before and after. Then move to the next machine.
Where REWO fits
Autonomous maintenance standards can be written as REWO guides with video, opened from a QR code on the machine, and the daily checks as Forms with results recorded. Analytics shows which operators have confirmed which version of each standard.
