A cause and effect diagram, often known as a “fishbone” diagram, can aid in brainstorming to find potential causes of a problem and in categorizing ideas. A fishbone diagram is a graphic representation of cause and effect. It is a more systematic technique than some other tools for brainstorming issue sources.

Ishikawa diagrams (also called fishbone diagrams, herringbone diagrams, cause-and-effect diagrams) are causal diagrams created by Kaoru Ishikawa that show the potential causes of a specific event.
Common uses of the Ishikawa diagram are product design and quality defect prevention to identify potential factors causing an overall effect. 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.
