Fishbone Diagram

"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:
(1) People: Anyone involved with the process;
(2) Methods: How the process is performed and the specific requirements for doing it, such as policies, procedures, rules, regulations and laws;
(3) Machines: Any equipment, computers, tools, etc. required to accomplish the job;
(4) Materials: Raw materials, parts, pens, paper, etc. used to produce the final product;
(5) Measurements: Data generated from the process that are used to evaluate its quality;
(6) Environment: The conditions, such as location, time, temperature, and culture in which the process operates. ...
Ishikawa diagrams were popularized 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.
The basic concept was first used in the 1920s, and is considered one of the seven basic tools of quality control." [Ishikawa diagram. Wikipedia]
