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
The history of all things He knew that any given thing on the face of the earth could reveal the history of all things...Actually, it wasn't that those things, in themselves, revealed anything at all; it was just that people, looking at what was occurring around them, could find a means of penetration to the Soul of the World. Paulo Coelho, The Alchemist A simple grain of sand history
