The Cause and Effect Diagram aims to show all the causes leading to some head event. It is an effective tool that allows people to easily see the relationship between factors to study, processes, situations, and for planning.
A Cause and Effect Diagram (also called a Fish bone Diagram or Ishikawa Diagram) is used to provide a pictorial display of a list in which you identify and organise possible causes of problems, or factors needed to ensure success of some effort.
