For a small manufacturer, an unexpected machine breakdown is more than an inconvenience - it means missed deliveries, idle operators and emergency repair costs. Total Productive Maintenance (TPM) is the lean answer to chronic downtime.
What is TPM?
TPM moves maintenance from "fix it when it breaks" to "prevent it from breaking." It does this by making equipment care a shared responsibility between operators and the maintenance team, rather than something only specialists do.
The idea of OEE
TPM is usually measured through Overall Equipment Effectiveness (OEE), which combines three factors:
- Availability - is the machine running when it should be?
- Performance - is it running at the right speed?
- Quality - is it producing good parts first time?
Many SMEs are shocked to learn their real OEE is 40-60% when they first measure it. That gap is hidden capacity you have already paid for.
Where to start
1. Autonomous maintenance. Train operators to clean, inspect, lubricate and tighten their own machines daily. They notice early warning signs long before a breakdown.
2. Track your losses. Log every stoppage - cause and duration. Within weeks a few "bad actor" machines and recurring problems will stand out.
3. Plan maintenance. Use the data to schedule preventive work during planned stops instead of reacting to failures.
The payoff
Plants that adopt TPM typically see fewer breakdowns, longer equipment life, lower spare-parts spend and far more reliable delivery - all without buying new machines. For a Chennai SME, that reliability can be the difference between keeping and losing a key customer.
