Fish heads are the problem, and the reason is that fish bones

Fish heads are of course the profits of stores, and big fish bones are the major items such as people, raw materials, customers, services and environment. "low efficiency" and "waste of personnel" are the small fishbones of this item; "Bad attitude", "Nobody served", "Nobody ordered" and "There was a demand that could not be solved" are the small fishbones serving this item. Of course, these fishbones can be further divided until finer fishbones are found out. By analogy, we can easily find out the real reason why the store's profit is not ideal.
