Final answer:
A fishbone diagram is used to categorize potential causes of a problem and identify the root causes.
Step-by-step explanation:
A fishbone diagram, also known as a cause-and-effect diagram or Ishikawa diagram, is a visual tool used to categorize potential causes of a problem. It is typically used in quality management and problem-solving processes to identify the root causes of an issue. The diagram resembles the shape of a fish skeleton, with the problem or effect being represented as the fish's head and the potential causes branching out like bones. Each branch of the diagram represents a category of causes, such as people, methods, materials, machines, or the environment. By using a fishbone diagram, you can systematically analyze the various factors that contribute to a problem and identify the key causes that need to be addressed.
