Who is credited with refining an idea for Just-In-Time systems at Toyota Motors?

Tai-ichi Ohno is credited with refining the Just-In-Time (JIT) production system at Toyota Motors. He was instrumental in developing the Toyota Production System, which emphasized efficiency, waste reduction, and the importance of producing only what is needed, when it is needed. This approach transformed manufacturing processes, allowing Toyota to reduce inventory costs and enhance production flexibility and responsiveness to customer demand.

Ohno's work involved implementing practices that minimized lead times and promoted continuous improvement, key aspects of JIT. His philosophy of eliminating waste in all forms has had a lasting impact not just at Toyota, but throughout the automotive industry and beyond. JIT remains a foundational element of Lean manufacturing principles, which have become widely adopted in various sectors as a means to improve operational efficiency.
