Fishbone Diagram Where does it come from

Where does it come from

Dr Kaoru Ishikawa developed the “Fishbone Diagram” at the University of Tokyo in 1943. Hence the Fishbone Diagram is frequently referred to as an “Ishikawa Diagram”. Another name for this diagram is the “Cause & Effect” or CE diagram. As illustrated below, a completed Fishbone diagram includes a central “spine” and several branches reminiscent of a fish skeleton. This diagram is used in process improvement methods to identify all of the contributing root causes likely to be causing a problem. The Fishbone chart is an initial step in the screening process. After identifying the potential root cause(s), further testing will be necessary to confirm the true root cause(s). This methodology can be used on any type of problem and can be tailored by the user to fit the circumstances.
