You sound like a person who has difficulty operating in an uncertain environment. Sometimes certainty is expensive. In fact, in my experience with complex systems, it usually is. Depending on what you're uncertain about, you may need to modify the system to measure it. Resolving uncertainty can take a long time, particularly if the thing you're trying to be certain about is a rare event or cannot easily be isolated. When certainty is hard to achieve, making probabilistic decisions sooner and falling back to more costly decisions with more expensive certainty only after those have failed, is a better general strategy, even if you're sometimes wrong. Analysis paralysis is real. Someone who always acts the way you suggest has too much fear of being wrong, IMO. It could be warranted in other situations, where human life is on the line. I think it's not a fast enough process for most businesses though.
