Charles PerrowWith a new afterword and a new postscript by the author
Normal Accidents analyzes the social side of technological risk. Charles Perrow argues that the conventional engineering approach to ensuring safety -- building in more warnings and safeguards -- fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk -- complex versus linear interactions, and tight versus loose coupling -- this book provides a powerful framework for analyzing risks and the organizations that insist we run them.
