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 has 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 differing layers and types of defenses ...

It is also a subject of accident analysis, [4] and can be considered a prerequisite for effective policy making. To describe causal relationships between phenomena, non-quantitative visual notations are common, such as arrows, e.g. in the nitrogen cycle or many chemistry [ 5 ] [ 6 ] and mathematics [ 7 ] textbooks.
