Total Productive Maintenance (TPM)
Total productive maintenance (TPM) is a holistic approach that engages all employees, from operators to managers, in proactive maintenance activities to maximise equipment effectiveness and eliminate losses.
Total productive maintenance is a holistic maintenance philosophy that aims to maximise Overall Equipment Effectiveness (OEE) by engaging every level of the organisation, from machine operators to senior management, in equipment care. TPM originated in Japanese manufacturing in the 1970s and is built on eight pillars: autonomous maintenance, planned maintenance, quality maintenance, focused improvement, early equipment management, training and education, safety health and environment, and TPM in administration. A core principle is that operators who use the equipment daily are trained and empowered to perform basic cleaning, inspection, and lubrication tasks rather than leaving all maintenance to specialised technicians. This catches early signs of deterioration, frees technicians for complex work, and builds a culture of ownership. Implementation typically begins with a pilot line or asset group to demonstrate results before scaling across the operation, and progress is measured through OEE improvements, reduction in breakdowns, and the maturity of operator-led maintenance routines.
Why it matters
Organisations that implement TPM typically see significant improvements in equipment availability, product quality, and workplace safety. By eliminating the "I operate, you fix" divide, TPM reduces the backlog of minor issues that accumulate into major failures. It also generates rich data on equipment condition from operator inspections, enabling better planning and fewer emergency breakdowns.
How MapTrack helps
MapTrack supports TPM programmes by providing digital checklists for operator inspections, automated alerts when readings fall outside acceptable ranges, and dashboards that track OEE metrics across sites and asset classes.

Frequently asked questions
What is the difference between TPM and preventive maintenance?
Preventive maintenance is a specific strategy of servicing assets at set intervals. TPM is a broader management philosophy that includes preventive maintenance as one of its eight pillars but also encompasses operator involvement, continuous improvement, training, quality maintenance, and safety. TPM seeks to eliminate all losses, not just equipment failures, including speed losses, defect losses, and setup losses.
What is Overall Equipment Effectiveness (OEE)?
OEE is the primary metric used in TPM to measure how effectively equipment is being used. It is calculated as Availability multiplied by Performance multiplied by Quality, expressed as a percentage. An OEE of 100 per cent means the equipment runs at full speed, produces only good parts, and has no unplanned downtime. World-class OEE is generally considered to be 85 per cent or above.
How long does it take to implement TPM?
A full TPM implementation typically takes three to five years to mature, though measurable improvements are often visible within six to twelve months of starting. The initial phase focuses on restoring equipment to baseline condition and training operators in autonomous maintenance. Subsequent phases build out the remaining pillars and embed continuous improvement into the organisational culture.

Preventive Maintenance
Preventive maintenance (PM) is a proactive maintenance strategy in which assets are serviced at predetermined time or usage intervals to reduce the likelihood of failure. Tasks may include inspections, lubrication, filter changes, calibrations, and component replacements. PM schedules are typically based on manufacturer recommendations, regulatory requirements, or historical failure data.
Planned Maintenance
Planned maintenance is the umbrella term for all maintenance work that is scheduled and prepared in advance, as opposed to reactive repairs after a breakdown. It encompasses preventive maintenance, predictive maintenance, condition-based maintenance, and any other proactive approach where the work is identified, resourced, and timetabled before it is carried out. The goal is to maximise the proportion of work that is planned rather than reactive.
Equipment Utilisation
Equipment utilisation measures the extent to which available equipment is being productively used, typically expressed as a percentage of available time or capacity. It is calculated by dividing actual usage time (or output) by total available time (or maximum capacity). Utilisation data can come from meter readings, operator logs, GPS tracking, or telematics systems. It is a key operational efficiency metric in asset-intensive industries.
