    Swiss cheese model

    Model used in risk analysis

    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 which are "layered" behind each other.

    Therefore, in theory, lapses and weaknesses in one defense do not allow a risk to materialize (e.g. a hole in each slice in the stack aligning with holes in all other slices), since other defenses also exist (e.g. other slices of cheese), to prevent a single point of failure.

    Applications include aviation safety, engineering, healthcare, emergency
