is really diagrams really matters a lot business?? One of the most useful tools in problem solving is the Cause-Effect Diagram. Cause-effect diagrams were invented in Japan in 1943 by Kaoru Ishikawa as an aid to explaining how various factors in a complex process can be sorted out and related. Cause-effect diagrams are often referred to as fishbone diagrams because of their shape or Ishikawa diagrams after their inventor. Cause-effect diagrams are extremely useful for organizing input from a brainstorming session. Brainstorming, to be effective, should be freewheeling and without judgments. Data is developed without regard to order, relationships or relevance. Once the data is captured, however, we need to sort it out and show the various relationships.
