Over the years a large number of accident analysis techniques have been developed that recognise the importance of considering the environmental context and the role played by systemic failings at differing organisational levels. Some of these approaches are presented as frameworks or philosophies (e.g., Reason, 1990) while others are presented as methods (e.g., STAMP – Leveson, 2010; the Risk Management Framework – Rasmussen, 1997;AcciMaps – Svedung and Rasmussen, 2000). These techniques have been used to analyse a wide variety of domains and accident scenarios. The prevalence of different methods, and the numerous interpretations of each is most likely a result of the complexity bound within these domains, but it can also prove to be a challenge to those seeking some form of ‘route map’ of the territory as it applies to the analysis of systemic failure.
