INTRODUCTION• Dr. Kaoru Ishikawa, a Japanese quality control statistician,

invented the fishbone diagram. Therefore, it may be referred to as the Ishikawa diagram.

• It is also known as cause and effect diagram.• The fishbone diagram is an analysis tool that provides a

systematic way of looking at effects and the causes.• The purpose of the fishbone diagram is categorizing the many

potential causes of problems or issues in an orderly way and in identifying root causes.

Companies uses fish bone

• Dominos• SMTP mail routing• IT arena

USES OF FISHBONE DIAGRAM• It can be used to study a problem/issue and to determine the

root cause.

• It can be used to study all the possible reasons why a process is beginning to have difficulties, problems, or breakdowns.

• It can be used to study why a process is not performing properly or producing the desired results.

STEPS TO SOLVE THE PROBLEM

• - figure out the problem as “poor quality” and put it at the head of fish bone

• - identify the factors that may be part of the problem. These may be systems, equipment, materials, external forces, people.

• - Main causes may be divided into sub causes which form the fine lines that run off the major bones.

• - analyze the diagram and further action can be taken according to that.

TOOLS FOR FISHBONE DIAGRAM• For finding problems, the 5 M's are a useful tool in finding

possible causes to a problem.• Manpower • Materials• Methods• Machines• Measurement

TOOLS FOR FISHBONE DIAGRAM• For problems that are being examined in the service industry,

the 5 P's can be used to develop the Cause Effect diagram• People (employees)• Provisions (supplies)• Procedures (processes)• Place (environment)• Patrons (customers)
