Drift into Failure From Hunting Broken Components to Understanding Complex Systems

'"Accidents come from relationships, not broken parts." Sidney Dekker's meticulously researched and engagingly written Drift into Failure: From Hunting Broken Parts to Understanding Complex Systems explains complex system failures and offers practical recommendations for their investigation and prevention from the combined perspectives of unruly technology, complexity theory, and post-Newtonian analysis. A valuable source book for anyone responsible for, or interested in, organizational safety.' Steven P. Bezman, Aviation safety researcher 'Dekker's book challenges the current prevalent notions about accident causation and system safety. He argues that even now, what profess to be systemic approaches to explaining accidents are still caught within a limited framework of 'cause and effect' thinking, with its origins in the work of Descartes and Newton. Instead, Dekker draws his inspiration from the science of complexity and theorises how seemingly reasonable actions at a local level may promulgate and proliferate in unseen (and unknowable) ways until finally some apparent system "failure" occurs. The book is liberally illustrated with detailed case studies to articulate these ideas. As with all Dekker's books, the text walks a fine line between making a persuasive argument and provoking an argument. Love it or hate it, you can't ignore it.' Don Harris, HFI Solutions Ltd 'Dekker's book contributes to the growing debate around the nature of retrospective investigations of safety-critical situations in complex systems. Both provocative and insightful, the author shines a powerful light on the severe limits of traditional linear approaches. His call for a diversity of voices and narratives, to deepen our understanding of accidents, will be welcomed in healthcare. Dekker's proposal that we shift from going "down and in" to "up and out" suggests a paradigm shift in accident investigation.' Rob Robson, Healthcare System Safety and Accountability, Canad
