1. First draw the main bone and fish head.

2. Then draw the big bones.

3. Finally draw the middle bones and small bones.

When drawing, make sure the big bone is at 60 degrees to the main bone, and the middle bone is parallel to the main bone. Then fill in the details.

The origin of the fishbone diagram: The fishbone diagram was invented by Mr. Kaoru Ishikawa, a Japanese management master, so it is also called the Ishikawa diagram. The fishbone diagram is a method of discovering the "root cause" of a problem. It can also be called an "Ishikawa" or "cause and effect diagram." Its characteristics are simple, practical, in-depth and intuitive. It looks somewhat like a fish bone, with the problem or flaw (i.e. the consequence) marked outside the "fish head". Possible causes of the problem are listed in order of likelihood, helping to illustrate how the causes interact with each other.
