What is a fishbone diagram and what is it used for?
A fishbone diagram, also called an Ishikawa or cause-and-effect diagram, is a tool for identifying the root causes of a problem. The problem sits at the head, while branches represent categories of possible causes. Teams use it to organize brainstorming and trace issues to their underlying sources rather than symptoms.
What are the main categories used in a fishbone diagram?
Common categories include people, process, equipment, materials, environment, and management, often summarized as the six Ms in manufacturing. Service or other contexts may adapt these. Each category forms a main branch, and contributing causes are added as smaller bones to explore where the problem may originate.
How do you create a fishbone diagram for root cause analysis?
Write the problem at the head of the diagram, then draw the spine and main category branches. For each category, brainstorm possible causes and add them as sub-branches, asking why repeatedly to dig deeper. Review the completed diagram to identify the most likely root causes to investigate and address.
