What is it?
A picture of various system elements that may contribute to the problem.
Helps to identify possible causes of a specified problem (or effect).
Used to root causes so that an improvement theory can be tried to fix the problem
Solutions should be based on root cause!
When is it used?
Answer “yes to one or both of these questions: 1. Do root causes of a problem need to be identified?
2. Are there ideas and/or opinions about the causes of a problem?

2. Record the problem statement.
3. Draw and label the main bones.
4. Brainstorm for problem causes.
5. Identify the most likely cause candidates.

Remember A graphic way to display a lot of cause information in a compact space Helps move from opinions to theories that can be tested (based on root cause)
Is critical to understanding how to make effective improvements View Cause & Effect Sample (Toolbook p. 51)
People Cause Instructional Materials Internal resistance to change Worksheets & games isolate skills State tests divided by content area Sub Cause Backbone Time Teachers have no knowledge on how to integrate State/National Requirements Methodology Low Integration of State Test Objectives Across Curriculum Areas
Identified Problem (effect)

Ways to Use the Cause and Effect Diagram
Why are students:
not paying attention in class?
forgetting their homework?
doing the wrong assignment?
being late to school?
doing poorly on tests?
taking too long to do an assignment?
Things to remember about the Fishbone Diagram
No judgments made about ideas
Everyone will have an opinion/voice about what causes a problem
Organizing these ideas improves the chance that good ideas can be tested.
Label the “main bones” of the diagram in ways that are best for your problem or event.
Customizing is encouraged!
Try It Out Cause and Effect Diagram
Work with a partner or your table
Brainstorm areas in a classroom that could be improved
Select one area for improvement
Use the Cause and Effect diagram to figure out possible root causes of the identified problem.
