What Is a Fishbone Diagram?
A Fishbone Diagram, a.k.a. Cause and Effect Diagram is used to identify the main causes of a problem in an organization or a system. Because a fishbone diagram helps organizations deeply analyze and find the root cause of an issue, it is sometimes referred to as the Root Cause Analysis diagram.

Preparations for Drawing Fishbone Diagram
As the name suggests, a fishbone diagram is drawn following the structure of the skeleton of a fish. A few important elements that the diagram has included:
- An optional fish-shaped outline that gives a visual boundary while assessing the issue. This outline is light and is there to give a rough structure of a fish in order to keep the focus of the analysts on the main effect and its causes.
- A broad, long main arrow facing toward the right side with the main problem written at the mouth of the fish, i.e. at the end of the arrow. This arrow looks like a spine of the fish’s skeleton.
- A couple of branches coming out from the spine (main line of the arrow) of the structure. These branches are labeled with the categories of the issues that caused the effect.
- Several sub-branches coming out from each category. These sub-branches are labeled with issues that eventually resulted in the main problem.
Note: Sub-branches may also have further sub-sub-branches if need be. The point is, the more details are provided the easier it would be to analyze the root cause of the effect.
By the time you’re done drawing a fishbone diagram, the entire illustration will look like a complex skeleton of a fish. That said, make sure to label each element in the diagram as you create it to avoid any confusion or error.
