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.

We feel it in our fingers In System A, there is no architect separate from the contractor. We are builders, simply. As builders, we have a direct feeling about construction. We feel it in our fingers, so it is down to earth. One result of this down-to-earth quality is that everything is somewhat experimental. We make experiments all the time. Sometimes we place a piece of wood this way. Another time, we may like to try it that way. Any time something new comes up in the design of a building, we are very likely to try and invent the best way of building it. This is not a great big invention. Just a simple invention, the way we might invent a way of tying a piece of string, to hold a broken toy together. It is just practical.
