It's a hard problem because there are no good answers.
> We need more trust and fewer metrics / games.
Except, at scale when dealing with a lot of people, there are plenty of people who are willing to abuse that trust.
I made this mistake early on in my career as a manager. I gave an important piece of work to one of the very senior engineers who I managed. Over the course of a month, he repeatedly said "trust me" regarding the status of his project. When 6 weeks went by and he finally showed it, it was in such a state that it was essentially unusable. We ended up throwing the whole thing out. Furthermore, he left for another job about two months after that, leaving his work in a shitty state.
I made plenty of mistakes there, but I also learned a valuable lesson, "trust but verify". Until someone shows me concrete evidence of what they've done, I really have nothing to go by.
To be clear, I'd love to be able to "have more trust and fewer metrics". But at the end of the day, it's really hard to give people the freedom to, say, hole up for months at a time while they say "trust me".
