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.
In the 1930s, Toyota Motor Co., Ltd. was a small Japanese automaker struggling to compete with larger American and European manufacturers. To overcome these challenges, Kiichiro Toyoda, the son of the company's founder, introduced the concept of "just-in-time" (JIT) production, which aimed to produce and deliver products just in time to meet customer demand.
Ohno realized that mass production created a dangerous illusion of efficiency. Producing large batches of a single part kept machines running, but it filled warehouses with costly inventory that masked underlying defects. Ohno shifted the focus from maximizing machine uptime to smoothing the flow of materials through the entire factory. 3. The Two Pillars of the Toyota Production System
Applying lean principles to reduce energy consumption and environmental impact. Conclusion
Mass production thrives on long runs of identical products to minimize changeover times. However, this creates severe demand spikes and inventory gluts when consumer preferences fluctuate.

Continuous improvement, or Kaizen , is impossible without standard work. Standardized work represents the best, safest, and most efficient known method for completing a task. It is documented clearly and followed by every operator.
Ohno was inspired by the work of Henry Ford, who had pioneered the concept of the assembly line. However, Ohno realized that Ford's system was not adaptable to the diverse and changing needs of the post-war Japanese market. Ohno set out to create a new production system that would allow Toyota to produce high-quality vehicles at a lower cost.
The company’s commitment to quality was inherited from Kiichiro's father, , who invented an automated loom that stopped automatically when a thread broke. This principle, known as Jidoka (autonomation) , became the second pillar of TPS, ensuring that machines and workers do not produce defective parts.
