Risk *309. A “risk” is a factor that could Result in a future negative consequence.

An uncertainty becomes a “risk” when it implies a potential that a future Result will be negative in relation to a planned or estimated target. (I am well aware of the field definitions used in Economics for Risk and uncertainty [BERNSTEIN96], and the history of making a distinction (for example, the Work of Frank Knight and J. M. Keynes). However, the definitions here are tailored to System Engineering purposes, rather than Economics.)
