The fishbone diagram, also known as the cause-and-effect diagram, is a visual thinking tool developed by Dr. Kaoru Ishikawa. It gets its name from its resemblance to a fish skeleton or fish backbone, with the problem or effect at the head of the fish, and causes branching out like bones.

Understanding the Basics

At its core, a fishbone diagram has a simple structure. It starts with the problem or effect at one end, symbolizing the 'head' of the fish. The 'bones', or causes, branch out from this central line, helping to clarify the main issues contributing to the problem. These causes can be further categorized into different types, such as people, processes, equipment, or other resources.
