BP Oil Spill and Swiss Cheese: Other Examples on Web

Some times it is nice to know that your view of something is shared by others and its seems that the Swiss cheese view of the BP oil spill is one of these views (maybe one day I will think of something new under the sun!). Tim Webb in the Observer on 18th July noted the BP executives used the ‘Swiss cheese’ analogy to explain how accidents occur. MasterResource, a free-market energy blog has some comments about the Swiss cheese model. BP’s "Leading from the top in BP" powerpoint makes reference to the Swiss cheese model of accidents. These are just a few examples from a quick search of the Web - I am sure there will be a lot more out there. So the concepts in model are clearly known about. How are they actually applied in practice if they are so well known?
