Further analysis using the Pareto diagram identifies specific defects in the tofu product, such as dirty tofu, incorrect size, unpleasant texture, and bad odor. The proposed improvements include scheduling regular equipment cleaning, ensuring the maintenance and cleanliness of production machines, and maintaining a clean working environment to prevent contamination of tofu products
