Not just bad managers. At large companies the processes and leadership structure are sometimes too focused on meeting dates (usually arbitrary) and sticking to the initial plan/design. I get that we won't change course for everything or we will end up with scope creep or in a loop of refactoring, but it would make sense for the items with the largest benefit or clear net value-add.
a bad manager would.
But also, an engineer capable of this is basically CxO material - which threatens said manager's career progress!
