The advantage of using this tool is that causes are arranged. It is often used in Lean Six Sigma and other quality improvement approaches to narrow down the area of analysis. Start with 4-6 main categories and expand as needed.

This cause analysis tool is considered one of the seven basic quality tools. A higher process capability index means. Fishbone diagram or Ishikawa diagram is a modern quality management tool that explains the cause and effect relationship for any quality issue that has arisen or that may arise.

In other words it is a visual representation used to find out the cause s of a specific problem. A cause-effect diagram is a visual tool used to logically organize possible causes for a specific problem or effect by graphically displaying them in increasing detail suggesting causal relationships among theories. It allows team members to separate a.
