What does "jidoka" refer to in lean manufacturing?

"Jidoka" refers to a principle in lean manufacturing that emphasizes the importance of building quality into the production process by automatically detecting defects and halting operations when a problem is identified. This concept allows machines and operators to stop production at the point of a problem, which enables immediate attention to the issue, preventing defective products from continuing through the manufacturing process. By doing so, it empowers workers and machines to identify quality issues in real time, ensuring that corrective actions can be taken swiftly to resolve the underlying problems.

This principle is an essential component of the Toyota Production System and contributes significantly to overall efficiency and quality in manufacturing operations. It reflects a commitment to continuous improvement and a proactive approach to quality management. As a result, "jidoka" significantly enhances operational resilience by fostering an environment where problems are not masked but rather addressed directly, leading to improved production outcomes.
