A key principles of TPM is to elevate the humble maintenance task to be a serious part of the
production process, rather than a bunch of fix-it mechanics or a 'when there's time' activity. It
also aims to be more efficient than Preventive Maintenance (PM) which can be over-zealous in
its regular servicing, even when it is not necessary.
The major losses of TPM are:
Breakdown
Equipment failure
Set up time
Start-up
Other downtime
Minor stoppages and idling
Reduced speed
Defects and rework
Waiting for management
Logistics
Operating movements
Measurement and adjustment
Line organization
Energy
Yield

This a concept where there is no such maintenance personnel .The person who is handling
machine ie operator himself is responsible for maintenance .
