This document provides an overview of the 5W1H method for analyzing processes, problems, or incidents. 5W1H involves asking who, what, where, when, why, and how questions to fully understand key details and infer the underlying facts and core issues. The "why" question is often asked multiple times to drill down to the root cause of a problem. 5W1H can be applied in fields like communication, education, journalism, business, and crime analysis to comprehensively examine situations or decisions.
