   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.[1][2] 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
