Lean's roots in the Toyota Production System and its adaptation across industries
In the 1940s, Kiichiro Toyoda, the founder of Toyota, faced a daunting challenge: how to produce high-quality cars with limited resources. He turned to his team, led by Taiichi Ohno and Shigeo Shingo, to develop a new approach. Thus, the Toyota Production System (TPS) was born.
TPS focused on two main goals:
- Eliminating waste (muda, in Japanese): reducing unnecessary steps, inventory, and defects.
- Improving flow (kaizen): continuously enhancing processes to create a smoother, more efficient workflow.
This innovative approach transformed Toyota into one of the world’s leading automakers. But Lean’s impact didn’t stop there. What is lean
