This diagram is known as a fishbone diagram because of its shape which is similar to the side view of a fish skeleton. The diagrams were popularized in the 1960s by Kaoru Ishikawa. Since Fishbone Diagrams are a causal diagram, each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify and classify these sources of variation. This causal analysis is intended to reveal key relationships among various variables, and the possible causes provide additional insight into process behavior. You can notice the causal relations in the following examples of the diagram.
