Numbers and the magic of measuring the right thing
What you measure matters.
When you measure the wrong thing, you get the wrong thing. Perhaps you can be precise in your measurement, but precision is not significance.
On the other hand, when you are able to expose your work and your process to the right thing, to the metric that actually matters, good things happen.
We need to spend more time figuring out what to keep track of, and less time actually obsessing over the numbers that we are already measuring.
