TPM (Total Productive Management)
Original: https://cli.im/article/detail/1845
Origins of TPM
Originating from PM (Preventive Maintenance) in the United States during the 1960s, TPM (Total Productive Management) was expanded and innovated by Japanese practitioners. By 1981, it had evolved into a company-wide management system that achieved remarkable success in Japan. Subsequently adopted worldwide, the first TPM World Conference was held in Tokyo in 1991 with over 700 participants from 23 countries. Sweden's VOLVO and Singapore's NACHI INDUSTRIES PTE.LTD. became the first two non-Japanese companies to obtain TPM certification.
TPM has been implemented across Asia (South Korea, Taiwan, Singapore, Indonesia), Europe (Sweden, France, Italy, Finland, Norway), the Americas (Ford, P&G in the US; Brazil, Colombia in South America), with thousands of enterprises worldwide achieving astounding results. In Shenzhen and China's coastal regions, foreign-funded and private enterprises have begun adopting TPM practices.

Measured results from TPM-certified enterprises
Definition of TPM
(TPM = Total Productive Management)
- Aims to maximize production system efficiency
- Establishes preventive systems against all losses, defects, and accidents
- Involves all departments from production to R&D, sales, and administration
- Requires company-wide participation from executives to frontline workers
TPM challenges enterprises to eliminate all waste, defects, and safety incidents through six pillars of improvement:
- Equipment Maintenance
- Quality Assurance
- Individual Improvement
- Administrative Optimization
- Environmental Management
- Talent Development
Organizations may achieve significant results by implementing selected pillars based on their specific needs.
