All project work operates in the presence of uncertainty.
Uncertainty comes in two forms on projects and product development.
Reducible uncertainty (Epistemic) and Irreducible uncertainty (Aleatory).
There is a 3rd kind of uncertainty - Ontological - which is unknowable - if you're working in the presence of ontological uncertainty, you've got very little chance of success.
This book is about making decisions in the presence of uncertainty - reducible and irreducible.
And as always
If you're going to make a risk-informed decisions in the presence of reducible and irreducible uncertainties, estimates will be needed of the risk created by the uncertainty and the impact of that risk on the probability of success of your decision.
