How to Analyze Root Causes Using the Lovebug Diagram:
- Put the problem statement in the head of the fish and the major causes at the end of the major bones. Major causes include:
- Processes, machines, materials, measurement, people, environment
- Steps of a process (step 1, step 2, etc.)
- Whatever makes sense
- Begin with the most likely main cause.
- For each cause, ask "5 Whys."
- Circle one-to-five ROOT causes (end of the "5 whys" chain).
- Verify the root causes with data (Pareto chart or Scatter Diagram).
