What is TPM (Total Productive Maintenance)?
TPM stands for Total Productive Maintenance. It is a maintenance philosophy and methodology from industrial production aimed at minimising downtime, breakdowns and quality losses by involving everyone in the organisation in maintenance.
TPM originated in Japan (at Nippon Denso) and is closely connected with LEAN manufacturing and continuous improvement (Kaizen).
🧱 The 8 pillars of TPM
TPM rests on 8 fundamental pillars:
- Autonomous maintenance – Operators perform daily basic maintenance themselves
- Planned maintenance – Strategic and periodic maintenance by specialists
- Education and training – Improving the skills of operators and technicians
- Early equipment management – Preventing problems at the design stage of installations
- Quality maintenance – Preventing defects in order to safeguard quality
- TPM in administration – Involving support functions as well
- Safety, health and environment (SHE) – Minimising incidents and risks
- Improvement teams (Kaizen) – Continuous improvement through multidisciplinary teams
🎯 Goals of TPM
- Zero breakdowns
- Zero defects
- Zero accidents
- Maximum machine availability
- Less waste (Lean)
TPM is strongly focused on shop-floor ownership: operators are not just users, but also share responsibility for the condition of their machines.
🧠 TPM & OEE
TPM and OEE are closely linked. TPM aims to reduce losses across the three OEE factors: Availability, Performance and Quality.
Examples of losses TPM addresses:
- Unplanned downtime
- Changeover time
- Slow running
- Quality reject
🧰 TPM in practice
Example in a production environment:
- Operators clean, lubricate and inspect their own machines daily
- The maintenance department performs planned maintenance based on a CMMS
- Issues are recorded and resolved via improvement boards
- KPIs such as OEE are used to measure effectiveness
📌 In summary
TPM is a comprehensive maintenance strategy focused on prevention, collaboration and continuous improvement. It increases employee engagement, extends the service life of machines and improves production efficiency.
