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.

Time and space Tones appear placed and directed predominantly in time from before to now to later. Their juxtaposition in a musical composition is perceived within a prescribed sequence only. Horizontally, the tones follow each other, perhaps not in a straight line, but of necessity in a prescribed order and only in 1 direction – forward. Tones heard earlier fade, and those farther back disappear, vanish. We do not hear them backward. Colors appear connected predominantly in space. Therefore, as constellations they can be seen in any direction and at any speed. And as they remain, we can return to them repeatedly and in many ways. This remaining and not remaining, or vanishing and not vanishing, shows only 1 essential difference between the fields of tone and color. The accuracy of perception in one field is matched by the durability of retention in the other, demonstrating a curious reversal in visual and auditory memory.
