Abstract

Recently, Organizational accidents have occurred frequently in medical industry. A great number of hospitals have introduced a human defense-in-depth by doctors and nurses. However, a defense-in-depth could be contribute to accidents because they make systems more complexity, and hence more opaque, to the people who manage and operate them. In this study, we examine the validity of human defense-in-depths with laboratory experiments. Our results from laboratory experiments show that double defenses are the most effective for preventing accidents if a defense-in-depth consists of homogeneous defenses. In addition, a defense-in-depth are effective for preventing accidents if a defense-in-depth consists of heterogeneous defenses.
