The major difference between a routine investigation and an expanded investigation is that an expanded investigation requires a root cause analysis or the building of a causal tree.

During a root cause analysis, the investigator gathers information from individuals involved in the event by repeatedly asking why. This process elicits data at multiple levels and defines the actions and decisions leading up to the event.
