Estimates are our best guess — at the time
Every estimate predicts the future
But we are not fortune tellers..
our estimates become more accurate as a project progresses..
... estimates are little more than guesses, they deliver no value. Work that delivers no value is waste and so should be avoided.
There are lies, damn lies and estimates
