Annie Duke's approach to decision-making is helpful as most of our decisions when building software or a team are not falsifiable. It's not math. Often, we'll need to collect information, explain our reasoning, and use our intuition before deciding. Having a method will help us increase the probability of hitting the target, and maybe sometimes hitting the bull’s-eye: "The beauty of approaching each decision by first examining what you know is that little bit of knowledge can go a long way toward improving your aim. The more you know, the better equipped you are to counter uncertainty in your decision-making."
