A credo is a very strong belief that guides one's behaviour. In the industry, one credo is that of causality: things have a cause. So when accidents happen, the question is that of knowing what caused them.
But can their causes always be found? What if the answer was no? What impact would this have on company policies and accident investigations?
Erik Hollnagel revisits the notion of cause in complex systems and compiles a few messages for accident investigators.
