I’m so tired of this advice. Maybe metrics are bad, but the only thing worse than metrics is no metrics.
Discouraging an action just because it doesn’t work 100% of the time doesn’t seem efficient either.
The argument really should be that certain metrics are bad. Sure, propose a better one, but saying that leaders don’t think hard enough just because a metric turns out to have ill effects seems useless advice. How can you be certain in advance when you have thought hard enough?
A better approach is probably to recognize that metrics are hard. Keep an eye on them, iterate, and be willing to make mistakes as that’s the only way to improve.
