What is the definition of fishbone diagram?

A troubleshooting tool that can be used to visually diagram the causes and effects of a problem. Fishbone diagrams are often organized with 5 ME.

Class Vocabulary
5 ME		A term used to describe the 6 main causes of problems: man, method, machine, material, measurement, and environment. 5 ME is often used to organize the parts of a fishbone diagram.
80-20 rule		A principle stating that, in general, 80% of problems or effects arise from 20% of causes or factors. Pareto charts are often used to demonstrate the 80-20 rule.
black box		A term used to describe the part of a process that is not completely understood. The internal workings of a machine could be considered a black box by the operator.
brainstorming		An activity in which an individual or group rapidly lists ideas, problems, or solutions. Brainstorming can be used in the troubleshooting process to identify possible problem causes.
cause and effect diagram		A visual tool used to organize possible factors that contribute to a certain event or problem. A fishbone diagram is an example of a cause and effect diagram.
check sheet		A document used to collect data, such as machine performance statistics, during the troubleshooting process. It is generally a simple form that can be filled out on the shop floor.
environment		In 5 ME, the factor that represents the potential for error due to the surrounding area in which the process occurs. This and other factors in 5 ME are often organized in a fishbone diagram.
fishbone diagram		A troubleshooting tool that can be used to visually diagram the causes and effects of a problem. Fishbone diagrams are often organized with 5 ME.
machine		In 5 ME, the factor that represents the potential for error due to equipment performance. This and other factors in 5 ME are often organized in a fishbone diagram.
man		In 5 ME, the factor that represents the potential for human error. This and other factors in 5 ME are often organized in a fishbone diagram.
material		In 5 ME, the factor that represents the potential for error due to quality problems with stock or other items used in a process. This and other factors in 5 ME are often organized in a fishbone diagram.
measurement		In 5 ME, the factor that represents the potential for error due to problems with certain instruments. This and other factors in 5 ME are often organized in a fishbone diagram.
method		In 5 ME, the factor that represents the potential for error due to incorrect or outdated instructions and practices. This and other factors in 5 ME are often organized in a fishbone diagram.
Pareto chart		A visual tool used to identify the causes of problems that occur most frequently. Pareto charts are often used to demonstrate the 80-20 rule.
root cause		The origin of the problem. Troubleshooting attempts to identify the root cause of a problem rather than simply addressing the symptoms.
troubleshooting		A systematic approach to solving problems quickly and efficiently.
