In his piece entitled iPhone 5, John Gruber made a statement that really stuck out to me: […] but there is no benchmark, no tech spec, to measure nice. But you can feel it. And that is what resonates with millions of people around the world. As soon as I read this, I was struck by how true this statement is for companies like Intel, Google and Amazon that claim to be “metrics-driven”. The unfortunate side-effect is that they focus so much on metrics that they end up being driven only by metrics — which ultimately results in consistently sub-par experiences.
