“Everything is measurable, at least in principle. In practice, many things are difficult to measure. That’s exactly why measures have to be improved constantly.”

“Another common reaction is the claim that quality isn’t measurable – more romantic nonsense. Everything is measurable, at least in principle. In practice, many things are difficult to measure. That’s exactly why measures have to be improved constantly.

Then, inevitably, someone will bring up Goodhart’s Law: “When a measure becomes a target, it ceases to be a good measure.” But that is clearly wrong. Sorry, Goodhard. If you want to indeed optimize the measure, you get exactly what you asked for. The problem is that often the measure wasn’t what you wanted to begin with.”
