A quality control principle in lean manufacturing. As per this principle, production is automatically stopped due to any system error.
Jidoka is a Japanese term originated in the manufacturing industry, and was popularized by Toyota as part of their Toyota Production System (TPS), also known as Lean Manufacturing. Jidoka is often translated as “autonomation” ( a word combination of autonomous and automation) or “automation with a human touch.”
The principle behind jidoka is to empower machines to automatically detect abnormalities or defects in the production process and stop themselves, allowing human operators to intervene and resolve the issue. This approach helps to ensure the production of high-quality products by preventing defective items from being produced or passed on to the next stage of production.
Jidoka involves the integration of sensors, monitoring systems, and automated processes in manufacturing. By incorporating these elements, machines can identify deviations from standard conditions, such as variations in product dimensions or equipment malfunctions. When an abnormality is detected, the machine stops automatically, signaling to the operator that intervention is required.
Overall, jidoka plays a crucial role in achieving high-quality production, reducing waste, and fostering a culture of continuous improvement in manufacturing environments.
