What does the 5 Whys Technique involve?

• A. A brainstorming tree
• B. A method to implement change
• C. Drilling down to the underlying cause by repeatedly asking 'why'
• D. A structured observation check

Answer: (C)

The main concept tested is a problem‑solving approach that uncovers root causes by repeatedly asking why until the fundamental issue is revealed. This makes it a diagnostic method for quality improvement, not just spotting symptoms. The is the best description because it specifically involves drilling down by asking why multiple times, which helps teams move from surface problems to underlying process gaps. It isn’t about generating ideas through a brainstorming tree, nor is it a method to implement change by itself, and it isn’t a structured observation check used for data collection. For example, if a safety incident occurs, you would ask why multiple times to trace back through contributing factors—until you reach the deepest root cause rather than stopping at a second, more obvious cause.
