Which quality improvement tool is commonly used to visually map root causes of a problem in infection prevention?

• A. Ishikawa (fishbone) diagrams
• B. Control chart
• C. Scatter plot
• D. Pareto chart

Answer: (A)

Visualizing root causes is achieved most effectively with an Ishikawa (fishbone) diagram. This tool organizes possible contributing factors into major categories along a spine, making it easy for a team to brainstorm and see how people, processes, equipment, materials, and environment interact to produce a problem. By laying out causes in a cause-and-effect structure, teams can trace back to underlying issues and target interventions precisely where they will have the most impact. A control chart, in contrast, is about monitoring process performance over time to detect variation. A scatter plot shows how two variables relate to each other, which helps explore correlations but doesn’t provide a structured map of root causes. A Pareto chart highlights the most frequent or impactful factors, useful for prioritization, but it doesn’t illustrate how multiple factors connect to the problem.
