The Swiss cheese model of accident causation is a model used in risk analysis and risk management.

These observations are then kept track of as incidents, which are then used to solve practical problems and develop broad psychological principles.
In accident analysis it could be used to determine leading factors, post-incident. This model works like a flow chart to help show all processes and systems that may have effected the outcome of the incident. Failure Mode and Effect Analysis: This model uses a quantitative value to represent qualitative metrics like probability and severity ...

[2] This strategy places more emphasis on research and analysis as well as crime prevention and the engagement of public and private organizations in the reduction of community ...
