Marty Cagan: Oh, I mean, it's funny. So first of all, and I should always say this at the very beginning. Whenever I work with teams, I always try to remember to say this somewhere. Nothing I talk about, and honestly being very clear, nothing I've written about in Inspired, nothing I've written about in Empowered was invented by us. All we do is share the practices we see being used in the best teams. So the heuristic is pretty easy. If it's used by several of the best teams, we're like, "Okay, let's start recommending it. Let's see how it works there. And if it works well, we'll start advocating it." And on the other hand, somebody says, "Oh, have you heard about this process? Or have you heard about this tool?" And if none of those companies are using it, I'm like, "Don't bother me. It's either snake oil or it's not proven yet."
It's either snake oil or it's not proven yet."
