Which quality improvement tool helps identify root causes in EMS?

• A. SWOT analysis
• B. Gantt chart
• C. Root cause analysis such as a fishbone/Ishikawa diagram and RCA process.
• D. Checklists only

Answer: (C)

When you want to fix EMS problems, you need to uncover what actually caused the issue, not just what happened. Root-cause analysis provides a structured way to dig into underlying factors and how they relate, so you can address the real drivers of a problem. Tools like a fishbone (Ishikawa) diagram help organize possible causes into categories such as people, processes, equipment, environment, and policies, showing how different factors connect. Then a formal RCA process investigates those potential causes, tests assumptions, collects evidence, and identifies which factor(s) truly led to the issue. With that clear, you can implement targeted changes and track their impact. Other options don’t focus on identifying underlying causes: SWOT analyzes strategic factors, Gantt charts plan timelines, and checklists help ensure steps are followed but don’t reveal root causes.
