Daniel Kahneman says, don't do it when you're in it. When you start, that's when you have to do it. Kill criteria are basically a list of what are the signals that I could be getting from the world that would tell me that I need to reevaluate this? Or in some cases that would tell us just flat out that we need to walk away. It's a pre commitment to quit if certain criteria aren't mad. And that's liberating for the team. The outcomes are going to come in the long run. Gary Kasparov talks about system mindset versus outcome mindset. You talk about focusing on decision quality rather than outcome.
