Who are pioneers of Just in Time techniques in Toyota?

• A. Ohno and Shingo
• B. Shing and Abe
• C. Deming and Dennis
• D. Deming and Ohno

Answer: (A)

Just in Time at Toyota is about producing only what’s needed, when it’s needed, and in the right amount, so workflows flow smoothly with minimal waste. Taiichi Ohno is the central figure who shaped the Toyota Production System and drove the JIT approach, introducing pull production, kanban signaling, and the idea of aligning output with actual demand. Shigeo Shingo complemented that work with key process improvements, especially SMED for fast changeovers and ideas that helped prevent defects, which are essential to making smaller lots and frequent, reliable signaling feasible. Put together, Ohno’s system design and Shingo’s engineering techniques embody the JIT techniques Toyota is known for.

Other options mix in figures not primarily associated with pioneering JIT at Toyota. Deming is famed for quality management and statistical process control, influencing Toyota’s broader quality culture but not as a JIT pioneer on the Toyota side. The other names listed aren’t recognized partners in developing Toyota’s JIT methods, and one is even a misspelling of Shingo.
