A comprehensive, company-wide maintenance and production management philosophy originating from Japan (developed by Seiichi Nakajima at JIPM in the 1960s-70s) that aims to maximize equipment effectiveness through the participation of all employees — from operators to top management — with the ultimate goals of zero breakdowns, zero defects, and zero accidents. Eight pillars: (1) Autonomous Maintenance (Jishu Hozen) — operators perform basic care (cleaning, lubrication, inspection, tightening). (2) Planned Maintenance — optimized PM/PdM schedules based on failure data. (3) Focused Improvement (Kobetsu Kaizen) — cross-functional teams eliminate the Six Big Losses. (4) Quality Maintenance — preventing defects at the equipment level. (5) Early Equipment Management — designing maintainability and reliability into new equipment. (6) Training and Education — developing multi-skilled workforce. (7) Safety, Health, and Environment — zero accidents. (8) TPM in Administration — extending lean principles to support functions. Central metric: OEE (Overall Equipment Effectiveness) — world-class target >85%. Implementation typically takes 3-5 years for full cultural integration. Per JIPM (Japan Institute of Plant Maintenance) TPM Excellence Award criteria. TPM is complementary to Lean Manufacturing and Six Sigma — together they form the foundation of operational excellence in world-class manufacturing.
