In 1924, Sakichi Toyoda invented an automatic loom that stopped instantly if a thread broke. This principle of "building in quality" at the source became a core pillar of TPS. the evolution of a manufacturing system at toyota pdf
: This introduced Jidoka (automation with a human touch), preventing the production of defective goods and allowing one operator to manage multiple machines. | Era | Timeframe | Core Innovation |
As Toyota’s own internal PDFs (like the manuals) show, the evolution was always about problem-solving , not tool adoption. A Kanban card without the discipline to stop the line and fix the root cause is just a piece of cardboard. As Toyota’s own internal PDFs (like the manuals)
Taiichi Ohno is the architect of the operational side of the system. He visited Ford plants in the US but realized he could not copy them. He inverted the logic of manufacturing.
The Toyota Production System (TPS) evolved from early 20th-century automatic looms into a comprehensive lean manufacturing model through key principles like Just-in-Time (JIT) and Jidoka. Official company history and modern integrated reports track this progression from post-war constraints to current digital innovations.
