Ishikawa Diagram (Fishbone Diagram)

An Ishikawa Diagram, also known as a Fishbone Diagram, is a visual tool used to identify and organize potential causes of a specific problem. It resembles a fish’s skeleton, with the problem at the head and main categories of causes branching out like bones. This helps teams systematically explore different factors—such as people, processes, materials, or equipment—that could contribute to the issue. By mapping these causes, it becomes easier to analyze root causes and develop effective solutions, supporting continuous improvement efforts.
