Here's my three point estimate paradox: We all know we must estimate with three points (numbers). so we do it, reluctantly None of us actually want to work with (do arithmetic with) the three points we estimate. In a word, three point estimates suck -- not convenient, thus often put aside even if estimated -- and most of all: who among us can do arithmetic with three point estimates? MORE
I work in a domain where estimates are made every single week. Estimate to Complete (ETC), Estimate at Completion (EAC), Estimated Completion Date (ECD) are the life blood of our software intensive system of systems programs. But Estimating is NOT Guessing. MORE
Estimating project work is fraught with opportunities for things to go badly. Or perhaps the project hasn't started yet and you're still putting time and energy into good solid work estimations that will turn into timeframes of effort in your master schedule. MORE

We all make estimates; and we all make estimates all the time. When I make the 20 mile trip each Tuesday to a client site, I estimate adjustments to a baseline based on weather and road construction and if I know about an accident.

There's a never-ending opportunity to learn how to estimate in the presence of uncertainty.

Since all risk comes from uncertainty - reducible (Epistemic) and irreducible (Aleatory), estimating is a foundation of all we do. There is no discussion of the conjecture that estimates are a waste, estimates can't be done, estimates are evil, estimates must be stopped immediately.
