Representing Operational Risk or Enterprise Risk Management for that matter as pieces of a puzzle has always been appealing and that appeal never seems to wear thin. It certainly used to be a bit of a fascination for me but the real magic of a risk framework design doesn't come from identifying the pieces of the puzzle specifically but from interconnecting these elements in a seamless manner.
Putting the pieces of a risk framework puzzle together still seems to be a challenge for risk managers, even today.
