What is the purpose of the 5 Whys root cause analysis technique?

• A. To assign blame to individuals involved in the incident.
• B. To collect data for regulatory reporting.
• C. To identify underlying causes by repeatedly asking why until fundamental factors are revealed.
• D. To map out all safety policies.

Answer: (C)

The idea behind the 5 Whys is to uncover the real cause of a problem by asking “why” several times. Each answer leads to the next question, guiding you from visible symptoms to deeper issues in a process or system. This helps you target fixes that prevent recurrence rather than blaming people or just collecting paperwork. It isn’t about assigning blame, gathering regulatory data, or outlining safety policies. Instead, you drill down to the underlying factor that, once addressed, stops the problem from happening again. For example, if a machine stops, you’d ask why it stopped, why that happened, and so on, to reach a root cause like insufficient maintenance or a faulty procedure, and then you implement corrective actions at that level.
