Accident Analysis - Methods

Methods

There exist numerous forms of Accident Analysis methods. These can be divided into three categories:

  1. Causal Analysis uses the principle of causality to determine the course of events. Though people casually speak of a "chain of events", results from Causal Analysis usually have the form of directed a-cyclic graphs-the nodes being events and the edges the cause-effect relations. Methods of Causal Analysis differ in their respective notion of causation.
  2. Expert Analysis relies on the knowledge and experience of field experts. This form of analysis usually lacks a rigorous (formal/semiformal) methodological approach. This usually affects falsify-ability and objectivity of analyses. This is of importance when conclusions are heavily disputed among experts.
  3. Organizational Analysis relies on systemic theories of organization. Most theories imply that if a system's behaviour stayed within the bounds of the ideal organization then no accidents can occur. Organizational Analysis can be falsified and results from analyses can be checked for objectivity. Choosing an organizational theory for accident analysis comes from the assumption that the system to be analysed conforms to that theory.
