Risk Management is How Adults Manage Projects - Tim Lister
Risk Management requires making estimates of many things. The uncertainties that create the risk - reducible (Epistemic) and irreducible (Aleatory), the impacts from the risks, the efficacy of the corrective actions, the residual reducible uncertainty, and any changes in the irreducible uncertainties.
Just like risk management, estimating is how adults manage projects. No risk management no adult managemnt. No estimates, no adult management. Since as that.
