Taguchi is known for his work on the loss function that first gained recognition in the 1980s. The Ishikawa diagram is more commonly referred to as a fishbone diagram or cause-and-effect diagram. It was developed in 1943 by Professor Kaora Ishikawa, president of the Musachi Institute of Technology in Tokyo.

The Ishikawa diagram is an excellent tool to apply to problem solving. For example, in the chart, the problem for a hospital pharmacy is identified as “late medications.” Brainstorming has elicited possible causes for this problem, recorded on appropriate “bones” or categories. The next step involves looking for the most likely cause(s), then collecting data about the current situation with respect to that cause.

Cal A. Braite might consider an Ishikawa diagram as he analyzes problems associated with his lecturing.
