Accident analysis

Its retrospective nature means that accident analysis is primarily an exercise of directed explanation; conducted using the theories or methods the analyst has to hand, which directs the way in which the events, aspects, or features of accident phenomena are highlighted and explained.

These analyses are also invaluable in determining ways to prevent future incidents from occurring.

They provide good insight by determining root causes, into what failures occurred that led to the incident.

Some common types of these models include the Five Why's model, Ishikawa (fishbone) diagram, the Fault Tree Analysis (FTA), or the Failure Mode and Effect Analysis (FMEA).
