Summary.
The Toyota Production System is arguably the most important invention in operations since Henry Ford’s Model T began rolling off the production line. It has spawned numerous approaches to improving operations, all based on the same principles: relentless attention to detail, commitment to data-driven experimentation, and charging workers with the ongoing task of increasing efficiency and eliminating waste in their jobs. This collection of ideas is often termed “lean.” Today most manufacturing companies and some service firms reap its rewards.
