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.

The minimum condition When a device is so designed that its component parts are only just strong enough to get the intended result without danger of failure, we may say it is in its minimum condition. I suspect that the functionalists sometimes meant by functional design simply design aimed at the minimum condition for a device. In that case 'form should follow function' would mean that every system should be in its minimum condition, thus having certain limitations imposed on its form.
