What are the three 'W' questions used in Mishap investigations?

• A. What Happened; Why did it happen; What to do about it
• B. When; Where; Who
• C. Who; What; Where
• D. Why; How; When

Answer: (A)

The three Ws guide mishap investigations by sequencing description, analysis, and action: first spell out What happened, then explore Why it happened, and finally decide What to do about it. This approach moves from documenting the event to uncovering causal factors, and then to implementing corrective measures to prevent recurrence. The correct option matches this flow: What Happened; Why did it happen; What to do about it. The other choices center on basic facts (When, Where, Who) or mix in How, which don’t provide the focused causal-analysis and action framework essential for effective investigations.
