ABOUT BOOK

"An unforeseen event may be defined as something that happens suddenly ~and unexpectedly. Such events are seldom the result of an organisation’s operational ~planning, but they can be side-effects of such planning. An unforeseen event may ~have either positive or negative consequences. This chapter aims to discuss if it is ~possible ~to prevent unforeseen events. The major focus is on analysis and prevention ~of unforeseen events with negative consequences, such as accidents, catastrophes ~and acts of terror. Such events often take place in complex systems, and failures of ~appropriate organisational interaction and communication among participants ~with complementary competence in such systems may contribute to unforeseen ~events. Risk-analysis methods and tools based on energy-barrier models, causal sequence ~and process models, as well as information-processing models are presented ~and their applicability to the prevention of unforeseen events is discussed. This also ~includes the Bow-tie approach, as well as other approaches which take into consideration ~organisational factors and social interaction (samhandling). The conclusion ~is that unforeseen events can be prevented. However, in the aftermath of the implementation ~of safety and security measures, it is not possible to know which events ~they prevented, or to obtain knowledge about their efficiency. An additional strategy ~for prevention of unforeseen events with negative consequences is proposed."
