The Swiss cheese model is a conceptual model used to illustrate how multiple layers of individual and organisational defenses can be penetrated by an accident or mistake, resulting in an undesired outcome.
This model is often used in the field of safety and risk management to analyze and prevent accidents and failures.
The model uses the metaphor of a slice of Swiss cheese, with each layer representing a different defense or barrier against potential hazards. The holes in the cheese represent gaps or weaknesses in the defenses, and when these align, the accident or mistake can occur.
The idea behind the Swiss cheese model is that by identifying and addressing these gaps and weaknesses, organisations can reduce the likelihood of accidents and failures.
