and do all of it with urgency (magically managers want everything done with urgency)
I'd argue that Boris Cherny is in fact nearly always wrong;
except when he's right, which is in the final pass just before the work is done. ;)
rest of us get fired if we ever admit at work that we were 'often' wrong.
This sounds like a slightly narcissistic manager who thinks people are doing it wrong if they don't act like small copies of him. There are multiple ways to reach the same outcome and a lot depends on your information. E.g. I typically have a mental model of a system in my head, meaning when some problem needs fixing very likely I already know where it would need fixing and already think about the various future implications arising from a different fix. A point that is totally absent from that framework.
Being a senior dev myself I have seen enough good software turn bad to know that seemingly innocent technological decisions can come with huge and lasting implications. The fact that this is missing here is speaking volumes about the lack of experience at display here.
Your task as a manager isn't to create small copies of yourself. Your task is to know each persons weaknesses and strengths and compose the work in such chunks that the weaknesses have little effect, while the strengths multiply. For this you will first of all have to trust your people and lead them to discover certain ideas themselves.
E.g. if you feel someone always jumps gun-ho I to the task without doing the research, just tell them to give you the research first. Do that a few times and they might realize how useful that is.
