In general only a handful of businesses correctly capture Operational Risk Loss Data and of those that do, only a small number of risk units in these firms are modelling their risk data in a coherent manner. After a bit of research on the internet and in various other channels, it has become relatively apparent that there isn't a comprehensive list of potential models which can be uses for understanding Operational Risk. I would have expected an analyst somewhere at some point in time to have done this and published it. None the less, this post achieves that goal.
