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.
