What is the name of the combined methodology that results from integrating the Why Method with the Sequence of Events Method?

• A. Sequence of Events: Why Method
• B. Root Cause Analysis
• C. Change Analysis
• D. Why Method Integrated

Answer: (A)

Sequence of Events: Why Method combines the timeline reconstruction with a why-analysis to trace root causes directly to specific events. The Sequence of Events part lays out what happened and when, listing actions, decisions, conditions, and failures in a clear order. The Why Method then interrogates each step in that sequence by asking why it occurred, digging deeper with iterative why questions to uncover underlying causes and contributing factors. When you connect the why questions to the exact points in the timeline, you identify root causes that actually explain how the incident unfolded, which makes the resulting corrective actions more effective and targeted.

Other options describe broader concepts or different focuses: Root Cause Analysis is a general approach to finding root causes without specifying the integrated timeline-spanning method; Change Analysis concentrates on changes and how they contributed, rather than building a full event sequence linked to causes; a term like Why Method Integrated isn’t the established name for this particular combination.
