1. The principle of full inspection: All parts and products must undergo full inspection.

2. The principle of in-process inspection: Quality is manufactured, so inspections must be carried out within the process.

3. The principle of stopping the production line: Once a defect is discovered in the process, the person familiar with it should immediately stop the production line (behavior) and take measures to eliminate the occurrence of the defect.

4. The principle of responsibility: In the event of a defective process, the operator must immediately carry out on-site repairs or corrections, and determine the scope of each person's responsibility.

5. The principle of arrest for current offenders: Once any misconduct occurs, it must be immediately confirmed by who did it, on which machine it was made, and with what materials it was made, without imagining the suspect's mentality.

6. The principle of thoroughly implementing standard operations: Standard operations refer to the regular and repetitive work actions of the operator in each cycle, and there must be inspection actions in each cycle. Is it okay?

7. The principle of different paths leading to the same goal: reducing work hours, allowing potential defects to manifest, thereby reducing defective products, while improving productivity and quality levels.

8. The inspection principle of N=2: If automatic machine batch production is used in the process, the inspection of the first and last products in each batch is equal to the principle of full inspection. This principle also applies to production lines that have been thoroughly standardized and have stable processes.

9. The principle of error prevention device: To prevent the occurrence of defects, we cannot rely solely on the attention of the operators, but must use error prevention devices to prevent human negligence and errors.

10. The principle of the inspection task is not to make selections, but to eliminate the objects that are the cause of the effort.

11. The principle of no complaints: To completely and thoroughly manage quality, with the goal of zero defects, and provide zero defect products to customers.

12. The principle of single piece flow: After completing a product, immediately move on to the next process, which means single piece flow. This is the basic method for early detection of defects and reduces handling, storage, and waiting, so the chances of defects occurring will also be reduced.

13. The principle of visual management: The production line should not be too long, and it should be organized by product, so that when there is an abnormality in the production line, it can be immediately understood where the abnormality occurred. This is called visual management.

14. The principle of clear tasks: The production goals, quality, and quantity of a production line should be clearly stated every day as the basis for improvement and maintenance.
