Why–because analysis
Method for accident analysis to determine causal relationships
Why–because analysis (WBA) is a method for accident analysis using graph theory.[1] It is independent of application domain and has been used to analyse, among others, aviation-, railway-, marine-, and computer-related accidents and incidents. It is mainly used as an after-the-fact (or a posteriori) analysis method. WBA strives to ensure objectivity, falsifiability and reproducibility of results.

The result of a WBA is a why–because graph (WBG), a type of causal notation used to represent interdependencies within a system. The WBG depicts causal relations between factors of an accident. It is a directed acyclic graph where the nodes of the graph are factors. Directed edges denote cause–effect relations between the factors.
