What is another name for a fishbone diagram?

1. Ishikawa Diagram

2. Scatter Diagram

3. Process Flow Diagram

4. Causes and Effect Diagram

The correct answer is: Process Flow Diagram

The correct name for a fishbone diagram is the Ishikawa Diagram. This type of diagram is used in quality management for identifying and visualizing various potential causes of a specific problem or effect. Developed by Kaoru Ishikawa, the fishbone diagram helps teams systematically catalogue all possible factors that could be contributing to an issue, making it easier to pinpoint the root causes. The other terms listed describe different tools or diagrams used in various contexts within quality improvement or data analysis. A scatter diagram, for example, shows the relationship between two variables. A process flow diagram outlines the steps in a process, providing a visual representation of the sequence of operations. A causes and effects diagram is indeed synonymous with the fishbone diagram, but it's typically less common than referencing it by Ishikawa's name. Thus, the term Ishikawa Diagram is the most widely accepted alternative name for the fishbone diagram.
