Fishbone diagram

Definition

A fishbone diagram, also known as an Ishikawa or cause-and-effect diagram, is a visual tool used to systematically identify and analyze the root causes of a specific problem or effect. This diagram resembles a fish's skeleton, with a central 'spine' representing the problem and 'bones' branching out to depict various potential causes categorized into different categories. It's an effective way to organize thoughts and facilitate discussions around complex issues.
