We optimize what we measure Scrum does not say “only focus on output”, but, unfortunately, humans will optimize for what they measure. If you worry about story points & hitting your estimations, that’s what is going to consume your attention. That is what you and your team will optimize for. And that is the core critique of Scrum as it is practiced: That it focuses a product team’s attention so heavily on delivery — on building lots of features quickly & efficiently — that teams fail to focus on spending time to discover what the right thing to build is.

So that you can get feedback on it and make it better Fascinatingly, one of the other big complaints people had about agile is no iteration. I don't understand how being in an agile environment makes people less iterative, but somehow that seems to be the case. And I think it's because people misunderstand and think that agile is just about putting features out faster, and not about the important part, which is getting something in front of users faster so that you can get feedback on it and make it better.
