Every factor identified in the diagram was included in the final design. The main causes included such aspects as 'touch' and 'braking' with the lesser causes including highly granular factors such as '50/50 weight distribution' and 'able to rest elbow on top of driver's door'. Mazda Motors famously used an Ishikawa diagram in the development of the Miata sports car, where the required result was 'Jinba Ittai' (Horse and Rider as One - jap. It is known as a fishbone diagram because of its shape, similar to the side view of a fish skeleton. It was first used in the 1940s, and is considered one of the seven basic tools of quality control. Ishikawa diagrams were proposed by Kaoru Ishikawa in the 1960s, who pioneered quality management processes in the Kawasaki shipyards, and in the process became one of the founding fathers of modern management.

Smaller arrows connect the sub-causes to major causes. Ishikawa diagram, in fishbone shape, showing factors of Equipment, Process, People, Materials, Environment and Management, all affecting the overall problem. Environment: The conditions, such as location, time, temperature, and culture in which the process operates.

Measurements: Data generated from the process that are used to evaluate its quality.Materials: Raw materials, parts, pens, paper, etc.Machines: Any equipment, computers, tools etc.Methods: How the process is performed and the specific requirements for doing it, such as policies, procedures, rules, regulations and laws.People: Anyone involved with the process.Causes are usually grouped into major categories to identify these sources of variation. Each cause or reason for imperfection is a source of variation. Common uses of the Ishikawa diagram are product design and quality defect prevention, to identify potential factors causing an overall effect. 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.
