Nearly 80% of airplane accidents are caused by human errors. About 50% of serious, undesirable incidents that occur in hospitals could be prevented by implementing measures such as checklists. Nevertheless, the medical world continues to view complications from a purely technical standpoint. In only a few exceptions are human behaviors and the influence of stress considered as factors in the chain of events leading to failures. This thought-provoking book offers some surprising answers to the question of how work practices can be improved, thus opening our eyes to the immense potential that lies within each of us. Both authors draw from their professional experiences, describing and analyzing their own mistakes while revealing a range of insights.
