Which tool helps identify root causes of adverse events without blaming individuals?

• A. A blame assignment chart
• B. A time-and-motion study
• C. A root cause analysis using methods such as the Ishikawa (Fishbone) diagram or the 5 Whys
• D. A performance appraisal form

Answer: (C)

Root cause analysis focuses on uncovering systemic factors that allow adverse events to occur, rather than blaming individuals. Tools like the Ishikawa diagram, or Fishbone diagram, help you map out potential causes into categories such as people, equipment, methods, materials, environment, and management, so you can see how different elements interact to contribute to the event. The 5 Whys technique takes a specific incident and asks why repeatedly, drilling down through layers of causes to reach the underlying process weaknesses or latent conditions. Used together, these methods steer you toward corrective actions that improve systems and prevent recurrence, with a focus on learning and safety rather than punishment. A blame assignment chart, by contrast, centers on identifying fault in individuals, which can suppress reporting and learning. A time-and-motion study looks at workflow efficiency and task timing rather than the deeper causes of harm. A performance appraisal form evaluates an individual’s performance, not the systemic factors that shape safety outcomes.
