Measurement with a goal
You can't manage what you don't measure say some (Feedback)
- The moment you choose to manage by a metric, you invite your managers to manipulate it. say others. Gaming The System, Goodhart's Law
But a measurement is a Model, in that it pretends to represent the Real World. How well does it represent Absolute Realty? In what Context? The more distant the observor is from the source of the metrics, the more risk there is in using the numbers.
Planning in terms of numbers can be helpful. But, as usual, the process is generally more useful than the outcome. And, when the future arrives, and you compare the prediction/plan to reality, can you "evaluate" someone as being "responsible" for any variance (Accountability)? Well, that is what happens in Markets, kinda. But when there's power involved (boss= Monopoly), it gets more dangerous...
