Measurements without consequences (rewards and punishments) is like giving a teenager a curfew and then not enforcing it. After very short period of time it gets ignored.
The adage what gets measured gets done is incomplete. What gets rewarded gets repeated is more complete.
If you establish a measurement it needs consequences both good and bad; otherwise, it will be ignored. By the way, if you have a teenager and you give them a curfew and don’t enforce it, your teenage will ignore the curfew.
