In project delivery, often we are asked to organize, study and plan for project risk. The classic Risk Assessment excercise where you identify issues (real, probable or made up) and assign a probability metric to a future event. This suggests Risk is measurable probability and this is often applicable and the more you are familiar with an area the more this can help.
But what about Uncertainty. This is when you don’t even know what you don’t even know. Uncertainty is when likelihood of future events is simply incalculable.
That’s why good Project Management or even business management works to deal with both. There may be a good amount of science and technology that will help us with Risk, but uncertainty is all in the art of coping with real life gotchas – kind of like the Human Factor.
