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.

Monkeys testing random designs A Tweet by Jared Spool twitter.com A/B testing is an effective approach to use science to design and deliver deeply-frustrating user experiences. A/B testing without upfront research is just random monkeys testing random designs to see which of those designs do “best” against random criteria. If drug testing was actually implemented like most A/B tests, you’d give 2 drugs to 2 groups of people and pick the “winner” by whichever group had fewer deaths. uxresearch
