Total Productive Maintenance from an engineering perspective — a comprehensive production system that maximizes equipment effectiveness by integrating maintenance activities into daily production operations through the active participation of all employees, from operators performing basic equipment care to engineers driving reliability improvement. The engineering focus within TPM's eight pillars: (1) Autonomous Maintenance (AM) — train operators to perform daily cleaning, lubrication, inspection, and tightening (CLIT) on their own equipment — this is the foundation of TPM. (2) Planned Maintenance — optimize PM/PdM schedules using failure data (MTBF, Weibull analysis), condition monitoring, and OEM recommendations. (3) Focused Improvement (Kobetsu Kaizen) — cross-functional teams use RCA tools to eliminate chronic equipment losses (the "Six Big Losses"). (4) Early Equipment Management — engineers design new equipment and modifications for reliability, maintainability, and operability (LCC approach). Central metric: OEE (Overall Equipment Effectiveness) = Availability × Performance × Quality; world-class target >85%. TPM implementation typically takes 3-5 years and requires sustained top-management commitment. Per JIPM (Japan Institute of Plant Maintenance). TPM integrates with Lean Manufacturing (waste elimination) and Six Sigma (variation reduction) for comprehensive operational excellence.
