Complex socio-technical systems fail; that is, accidents occur. And it is enormously important for engineers and policy makers to have a better way of thinking about accidents than is the current protocol following an air crash, a chemical plant fire, or the release of a contaminated drug. We need to understand better what the systems …

Charles Perrow is a leading researcher on the sociology of organizations, and he is a singular expert on accidents and system failures. Several of his books are classics in their field -- Normal Accidents: Living with High-Risk Technologies, The Next Catastrophe: Reducing Our Vulnerabilities to Natural, Industrial, and Terrorist Disasters, Organizing America: Wealth, Power, and the Origins of …

It is self-evident that we attribute causal powers to meso entities in ordinary interactions with the social world. We assent to statements like these; they make sense to us. Reorganization of the city's service departments …
