"Risk is failure of a projected narrative"

A ISO 9001 aborda a abordagem baseada no risco. 

“The Oxford Dictionary defines risk as ‘the possibility that something unpleasant or unwelcome will happen’,

…

Risk in its ordinary meaning concerns unfavourable events, not beneficial ones.

.

Risk is asymmetric. We do not hear people say ‘there is a risk that I might win the lottery’ because winning the lottery is not something they would describe as a risk. They do not even say ‘there is a risk I might not win the lottery’ because they do not realistically expect to win the lottery. The everyday meaning of risk refers to an adverse event which jeopardises the realistic expectations of the individual household or institution. And so the meaning of risk is a product of the plans and expectations of that household or institution. Risk is necessarily particular. It does not mean the same thing to J. P. Morgan as it does to a paraglider or mountain climber, or to a household saving for retirement or the children’s education.

…

Very often, the risks that concern us are not risks to the status quo, but risks to our plans to change that status quo.

…

We believe the best way to understand attitudes to risk is through the concept of a reference narrative, a story which is an expression of our realistic expectations. For J. P. Morgan, the overarching reference narrative is one in which the bank continues profitable growth. A large corporation will have many strategies for achieving that overarching objective in particular areas of its business and there will be a reference narrative relating to each business unit. Some of these business unit reference narratives may be very risky, but the corporation may tolerate such risks provided they do not endanger the reference narrative of the organisation as a whole.

…

And since different people start with different reference narratives, the same risk may be assessed by different people in different ways. Risk may not be the same for those who work in an organisation as it is for the shareholders of that organisation.

…

Risk is failure of a projected narrative, derived from realistic expectations, to unfold as envisaged. The happy father anticipating his daughter’s wedding has in mind a reference narrative in which events go ahead as planned. He recognises a variety of risks – the prospective bridegroom has cold feet, a torrential downpour drenches the guests. There is an implied measure of risk in such assessment – an outcome can fall short of expectations by a narrow margin or a wide one. The scale of that risk may or may not be quantifiable, before or after the event. But this interpretation is very different to the view that has come to dominate quantitative finance and much of economics and decision theory: that risk can be equated to the volatility of outcomes.”
