Quality Management Tools , 1. Cause and Effect Diagram

Cause and Effect diagram is also called as Fish Bone Diagram or Ishikawa Diagram or Root Cause Analysis Diagram . It was invented by Quality Pioneer Kaoru Ishikawa  in late 1960's which proved to be a very crucial method for finding out the root cause of any problem.

The aim of the Diagram is to find out the major or most important cause behind a certain problem which is shown in the form of the head of a fish and the bones are the causes in this.

The idea is that the various causes for the problem are categorized into :
  • People
  • Material
  • Environment
  • Machines
  • Methods
These categories have further sub causes and futher sub-sub causes , so the main idea is to find out the root cause ( major) .


The step by step working of the Tool shall be continued in next blog..keep reading..

Thanks.
