Mr. Perrow found that the organizations designed to run and safeguard modern technology were so complex and so tightly integrated that accidents are inevitable, or ''normal,'' even when all the proper safety procedures are followed. Thus, disasters like the near-meltdown of the nuclear reactor at Three Mile Island in Pennsylvania and the explosion of the Space Shuttle Challenger cannot be traced to discrete errors or blamed solely on ''operator error,'' as has been the typical approach in the past. They are the natural result of the systems themselves. They are accidents that are inconceivable -- until they happen.— New York Times
Overview
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 ...
