The quote in the title is from Tim Lister. It says volumes about project management and project failure. It also means that managing risk is managing in the presence of uncertainty. And managing in the presence of uncertainty means making estimates about the impacts of our decision on future outcomes. So you can invert the statement when you hear we can make decisions in the absence of estimates.
