This cause-and-effect diagram example was redesigned from the Wikimedia Commons file: Ishikawa Fishbone Diagram.svg. [commons.wikimedia.org/wiki/File:Ishikawa_Fishbone_Diagram.svg] "Ishikawa diagrams (also called fishbone diagrams, herringbone diagrams, cause-and-effect diagrams, or Fishikawa) are causal diagrams created by Kaoru Ishikawa (1968) that show the 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 these sources of variation. The categories typically include - People: Anyone involved with the process - Methods: How the process is performed and the specific requirements for doing it, such as policies, procedures, rules, regulations and laws - Machines: Any equipment, computers, tools, etc. required to accomplish the job - Materials: Raw materials, parts, pens, paper, etc. used to produce the final product - Measurements: Data generated from the process that are used to evaluate its quality - Environment: The conditions, such as location, time, temperature, and culture in which the process operates" [Ishikawa diagram.
