INTRODUCTIONThe Fishbone Diagram is tool for analyzing process dispersion. It is also referred to as the “Ishikawa Diagram", because professor Kaoru Ishikawa developed it at 1943 and the “Fishbone Diagram”, because the complete diagram resemble a Fish Skeleton. The diagram illustrates the main Causes and sub cause leading to an effect(Symptom)

ABSTRACT

Fishbone Diagram

KeywordsCause and effect DiagramIshikawa DiagramFishbone DiagramRoot Cause Diagram

OBJECTIVESThe main goal of the fishbone diagram is to illustrate in a graphical way the relationship between a given outcome and all the factors that influence this outcome. The main objectives are Determining the root cause of the problemFocusing on a specific issue without resorting

to complaints and irrelevant discusIdentifying areas where there is the lack of data

FIELD OF APPLICATIONThe fishbone diagram could be applied when it is wanted to:Focus attention on one specific issue or problemFocus the team on the causes, not the symptoms.Organize and display graphically the various theories about

what the root causes of a problem may beShow the relationship of various factors influencing a problemReveal important relationships among various variables and

possible causesProvide additional insight process behaviors

BENEFITSHelp determine root causeEncourages group participationUses an orderly, easy to read format to diagram cause

and effect relationships Indicates possible causes of variation Identifies areas for collecting data Increase knowledge of the process by helping

everyone to learn more about the factors at work and how they related

PREREQUISTESoA problem is composed of a limited

number cause, which are in turn composed of sub causes

oDistinguish these cause and sub cause is a useful step to deal with the problem

Where it is NOT APPLICABLEThe fishbone diagram is not applicable to every situation. Here are a just a few cases in which you should not use the fishbone diagram because the diagrams either are not relevant or do not produce the expected result. The problem is simple or is already know The team size is too small for brainstorming There is a communication problem among the team

members There is a time constraint, at or sufficient headcount is

not available for brainstorming

CONCLUSIONVisual diagram, resembles fish skeleton, identifies the causes of a problem(effect),and their relationships, created by kaoru ishikawa for quality management, increases communication about the problem, used to improve any product, process or service, identify major, secondary and tertiary causes and attach to backbone identifying relationship, analyze and evaluate result, act to fix the problem
