- 1950 Breakdown Maintenance. The repairing or fixing of equipment only after it has broken down.
- 1951 Preventative Maintenance. Preventative maintenance is aimed at the prevention of breakdowns.
Activities range from daily checks to maintenance
- 1954 Productive Maintenance. Productive maintenance is the maintaingin of certain conditions.
If these consist of optimal conditions for production, including output, then the productive maintenance process
is required to maintain it.
- 1959 Corrective Maintenance. Corrective maintenance goes a stage further than the replacing of worn or broken
parts. Corrective maintenance promotes the concept of repairing the machine in such a way that the same breakdown is
less likely to happen again.
- 1960 Maintenance Prevention. Maintenance prevention incorporates the equipment design stage. By using the
knowledge gained from the previous steps, machines will be built with ease of maintenance as a design parameter.
- 1970 Total Productive Maintenance. Total productive maintenance goes beyond the maintenance department to
involve the whole company in striving to achieve zero breakdowns and zero defects. TPM is characterised by production
workers participating in maintenance activities, based on the reasoning that the people most likely to notice strange
symptoms or abnormalities are the operators themselves.
A full TPM Programme consists of five pillars of development :
- Establish a system of "autonomous maintenance" to be performed by the operators thenselves.
- Implement improvement activities to increase equipment effectiveness. Eliminating '6' big losses. (Overall
Equipment Effectiveness).
- Establish preventative maintenance system.
- Establish training.
- Develop the use of maintenance provision.
