History of the Toyota Production System (TPS)

Summary

The Toyota Production System (TPS) revolutionized manufacturing by emphasizing waste elimination and quality through intelligent automation (jidoka) and Just in Time manufacturing. Originating from Sakichi Toyota's innovations in loom technology, TPS evolved under Kiichiro Toyota, who integrated these principles into automobile production. Key figures like Taiichi Ohno further refined the system after World War II, establishing efficient processes that linked production with supply chains. The TPS gained global recognition, especially after Toyota's resilience during the 1973 oil crisis. Today, it remains a model of operational excellence, continuously evolving to enhance product quality and productivity.
