That statistics should inform action or measure of efficacy, but not drive it.
A dev manager running on only numbers will inevitably get empty, meaningless values such as tickets resolved or lines of code written, while the polar opposite manager will run on intuition alone. I imagine most would agree neither type is generally effective and a balance should be struck, and Goodhart's Law means you should be aware of what's important, pay attention to it, but do not make it your sole focus. And for God's sake, don't make a public dashboard for it.
