It is great, I use them to self improve all the time, I like things that are critical of me, or show me where I am weak.

Everyone (including management) is aware of all of the tropes and cliches about how metrics cease to be good when they become targets and how metrics can be gamed blah blah blah - we all know that - and have imbibed that, but the rationale is that more (but imperfect) visibility is better than no visibility or solely subjective interpretations.

As long as all metrics are assumed to be wrong until proven correct, with some digging, some thorough analysis and a judicious and abundant use of the benefit of the doubt, I find them really helpful.
