„The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese, which have randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the different types of defenses which are “layered” behind each other. Therefore, in theory, lapses and weaknesses in one defense (e.g. a hole in one slice of cheese) do not allow a risk to materialize, since other defenses also exist (e.g. other slices of cheese), to prevent a single point of failure.“
↑ „The Swiss cheese model of accident causation illustrates that, although many layers of defense lie between hazards and accidents, there are flaws in each layer that, if aligned, can allow the accident to occur. In this diagram, three hazard vectors are stopped by the defenses, but one passes through where the “holes” are lined up.“
