Which JIT philosophy describes level production throughout the supply chain to match the planned rate of end product sales?

• A. Jidoka
• B. Kaizen
• C. Heijunka
• D. Andon

Answer: (C)

Level production to match demand means smoothing the production schedule so output runs at a constant pace that aligns with the planned rate of sales. This idea is embodied in Heijunka, which aims to level both production volume and product mix across time and the supply chain. By producing at a steady rate and distributing work evenly, the system reduces inventory, avoids peak loads, and helps ensure a reliable flow that matches customer demand.

Jidoka focuses on quality at the source and the ability to stop the line to fix defects. Kaizen is about ongoing improvement. Andon is the signaling system that alerts when problems occur. The described approach—steady, leveled production to match sales rate—best fits Heijunka.
