As a result of carrying our your Control Quality process, you discover that unfortunately these parts are frequently made with defects. You have decided to hold a meeting to discuss the process of making the parts. You create a diagram that has branches that show the possible causes of the problems. Each of the branches breaks the cause down into more and more detail. What is this diagram called?
