What are the two recommended analysis techniques?

• A. Fault Tree Analysis and 3-Column List (What we know, What we believe, What we need to know)
• B. Root Cause Analysis and Failure Mode Effects Analysis
• C. SWOT Analysis and Pareto Analysis
• D. Fishbone Diagram and Failure Mode Effects Analysis

Answer: (A)

The question is testing the use of a structured, early-stage analysis approach for mishap investigations. Fault Tree Analysis gives a clear, top-down map of how basic failure events can combine to produce the accident, using logical relationships to show which pathways lead to the top event. This helps you see where to focus evidence collection and which failure paths matter most, making causation more transparent and testable.

The 3-Column List (What we know, What we believe, What we need to know) provides a disciplined way to organize information from the start. It separates confirmed facts from assumptions and clearly flags information gaps, guiding subsequent data gathering and hypothesis testing. Pairing this with Fault Tree Analysis keeps the investigation both logically structured and knowledge-driven, which is exactly the approach taught for effective mishap analysis.

Other options mix tools that don’t provide the same combination of deductive causal mapping and explicit knowledge tracking, so they don’t align as well with the recommended method in this context.
