What is the purpose of Cause-and-Effect (Fishbone) Diagrams?

• A. To map organizational structure
• B. To identify root causes of a problem and support systems thinking
• C. To forecast budgets
• D. To track project milestones

Answer: (B)

Cause-and-effect diagrams are used to uncover the root causes of a problem by organizing potential contributing factors into categories and showing how they relate to the outcome. This approach encourages systems thinking, helping teams see how people, processes, equipment, materials, environment, and management practices interact to create the issue. By placing potential causes on a fishbone diagram, you can brainstorm, observe data patterns, test ideas, and focus improvement efforts on the underlying drivers rather than just the visible symptoms. In health department settings, this is especially useful for questions like delays in service, safety incidents, or quality problems because it guides targeted interventions that address root causes. It isn’t about mapping organizational structure, forecasting budgets, or tracking project milestones—that would use different tools such as organizational charts, financial models, or project plans.
