What is a Fishbone Diagram?
A fishbone diagram, also called a cause and effect diagram or Ishikawa diagram (named after Dr. Kaoru Ishikawa who invented it) , is a visualization tool for categorizing the potential causes of a problem in order to identify its root causes.
The Fishbone Diagram Design
The design of the diagram looks much like a skeleton of a fish. Fishbone diagrams are typically worked right to left, with each large “bone” of the fish branching out to include smaller bones containing more detail.
