Definition
From first-line operators to top-level full-time participation in equipment improvement to maximize resources, quality and full life cycle costs to eliminate operational waste.
In detail
Total Productive Maintenance (TPM) is a method that involves everyone from frontline operators to senior management in equipment improvement, aiming to maximize equipment effectiveness, resource utilization, and lifecycle cost efficiency, thereby eliminating operational waste. Within the system, it addresses equipment failures and downtime, complementing Standard Work (SW): SW standardizes human actions, while TPM ensures equipment condition. It differs from preventive maintenance in that TPM emphasizes autonomous maintenance and total participation, whereas preventive maintenance is periodic maintenance by a dedicated maintenance team. Typical outputs include OEE metrics, autonomous maintenance checklists, equipment improvement case studies, and training records.
Example in practice
When a critical piece of equipment frequently fails, causing production interruptions, the company implements TPM, organizing operators for autonomous maintenance training, having them perform daily inspections and cleaning, and record abnormalities. Meanwhile, the maintenance team develops a preventive maintenance plan based on historical data. After several months of operation, equipment failure rates decrease, operators' sense of responsibility for equipment increases, OEE improves, and production plans become more stable.
