A Cause and Effect Diagram is a tool that helps identify, sort, and display possible causes of a specific problem or quality characteristic. It graphically illustrates the relationship between a given outcome and all the factors that influence the outcome.
A Cause and Effect Diagram is sometimes called an “Ishikawa diagram” because it was invented by Kaoru Ishikawa, or a “fishbone diagram” because of the way it looks. The structure provided by the diagram helps team members think in a very systematic way.
The Cause and Effects Diagram:
- Helps determine root causes
- Encourages group participation
- Uses an orderly, easy-to-read format
- Indicates possible causes of variation
- Increases process knowledge
- Identifies areas for collecting data

Focused Problem Statement
- A cause and effect diagram is most effective when you create a focused problem statement.
- By focusing the problem statement you will narrow the scope of your analysis.
- It will be difficult to create a cause and effect diagram if the scope of the problem is large because there will be a lot of potential causes.
