Fish Bone Diagram

Kaoru Ishikawa invented the fishbone diagram in the 1960s. He was a Japanese professor and a quality management innovator of his time. The fishbone diagram is also known as the Ishikawa diagram, as a tribute to its creator. A fish-bone diagram is one of the seven quality circles (QC) tools. It helps to visualize the potential causes to find the root cause of a particular problem. It helps to identify, analyze, and improve quality issues. Sometimes, it can also be helpful to analyze what can go wrong – preventing future problems.
