For those who have the image of a pretty blonde dairymaid bob up in their minds, who is posing with a big wheel of cheese next to a cow, in front of a beautiful backdrop of the Swiss alps, when they hear the words “Swiss Cheese model”, you are on the wrong track. In fact, according to Wikipedia, the “Swiss Cheese model of accident causation is a model used in risk analysis and risk management, including aviation, engineering, healthcare, etc.”

I don’t want to go into too much detail here, but the basic essence of this model seems to be: If you want to be safe, get cheese with tiny holes and cut it into many layers. Or something along those lines.
