This diagram is also complemented with why analysis. It is the method adopted for Lean Six Sigma, a query decoding tool. Split the causes into sub-causes, till you cannot drill it down furtherįishbone diagrams are practiced in the “Analyze” stage of the DMAIC – define, measure, analyze, improve, and control.Combine these elements to the category branches, respectively. Analyze the causes of these categories that contribute to the effect.Name the areas, broad level categories, to be thought and branch them from the backbone.Sketch a decent line from the head, heading to the left.Sketch the head on the right which includes the problem effect or issue for investigation.The branching depends on the standards required under each group. The ribs indicate levels or order of objectives for the analysis, which branch out into causes and sub-causes. The “bones” extend on the left side to show the various causes. The “head” of the skeleton represents the difficulty or influence, which is generally shown on the right side. It acquires its name for its appearance shape which matches the side aspect of the skeleton of a fish. Sometimes, it can also be desirable to analyze what can go wrong – preventing future difficulties. It helps to recognize, analyze and fix quality issues.
It serves to reflect the potential causes in line to obtain the root cause of a particular query. The Fishbone diagram is 1 of the seven quality circles (QC). The fishbone diagram is also recognized as the Ishikawa diagram and the Cause and Effect diagram. He practiced this tool for the first season when he served with the Kawasaki shipyards in the quality management process. He was a Japanese teacher and a quality management lecturer of his generation. In the 1960s Kaoru Ishikawa discovered the fishbone diagram.
