Jidoka is a key principle in the Toyota Production System that emphasizes quality control during the manufacturing process. It allows machines and workers to detect defects or abnormalities and stop production immediately. This approach helps prevent defective products from being made and encourages a culture of continuous improvement. The term "jidoka" translates to "automation with a human touch." It empowers employees to take responsibility for quality, enabling them to halt production if they notice a problem. By integrating this principle, companies can enhance efficiency and ensure that only high-quality products reach the market.
