3. INTRODUCTION
The 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)

4. ABSTRACT

5. Fishbone Diagram

6. Keywords
Cause and effect Diagram
Ishikawa Diagram
Fishbone Diagram
Root Cause Diagram

7. OBJECTIVES
The 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 problem
Focusing on a specific issue without resorting
to complaints and irrelevant discus
Identifying areas where there is the lack of
data

8. FIELD OF APPLICATION
The fishbone diagram could be applied when it is wanted to:
Focus attention on one specific issue or problem
Focus the team on the causes, not the symptoms.
Organize and display graphically the various theories
about what the root causes of a problem may be
Show the relationship of various factors influencing a
problem
Reveal important relationships among various variables
and possible causes
Provide additional insight process behaviors

9. BENEFITS
Help determine root cause
Encourages group participation
Uses 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

10. PREREQUISTES
oA 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

11. Where it is NOT APPLICABLE
The 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

12. CONCLUSION
Visual 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
