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. Henry Latham, Why Scrum is killing your product optimizationagilefeatures
Pointing "Originally I marked these places, quite literally. I laid a small concrete block flush to the ground at the place where I was standing and stretched a stainless steel piano wire out toward the horizon. It might go off a mile; it simply pointed in a direction. And that was the piece." Lawrence Wechler & Robert Irwin, Seeing Is Forgetting the Name of the Thing One Sees Pointing at things place
