This kind of graphics can be drawn first, and then the cause of defects can be recorded in each process. Since the quality problem is generated during the weaving process, the The process flow discussion causes the quality problems and can be processed in different categories. This method
is easy to draw and easy to understand. Its disadvantages It is sometimes repeated for the same reason, and several originals can be easily expressed when they affect the quality at the same time.
