The complaint about OKRs - using only specific meazurements to destroy the ability to decide/agency to land actual outcomes/results - seemed pretty spot on. It's not even engineering managers necessarily; knowledge working orgs in general, and, in my view, it's not immature to grumble about, it's immature orgs that ruin their best potential, that dont get knowledge work & actively obstruct it.

Having these ideas in mind, particularly backed up by some good background as is present here - some discussion on knowledge work, Peter Drucker quotes - is context orgs ought to try to be aware of, prevent from happening.

Sad to see such a well written well explained article reduced to "grow out of their mindset" antagonism. There's not any argumentation in this rebuttal, just personal badmouthing & berating. The conflict described is real, but apparently people who feel tensions & dissonance of it all are all just "immature".
