Actual management is hard! Companies are completely chaotic systems, and every important feature comes as much from the details as they do from the big picture.
Most people are completely unable to work with that, what includes a large majority of the managers on every level. Worse yet, it's never clear if a good or bad result happened because of somebody's work or despite it, so the feedback is completely unreliable and it's incredibly hard for people to improve.
And yet, I've never seen anybody teaching "management" to even acknowledging any of the complexity. (Including famous authors and professors.)
I think W.E. Deming had some very good practical advice that I rarely see actioned. One place I worked, there was an entire volume of Deming's books on a shelf you had to pass to get to the cafeteria. But his advice wasn't being heeded. Why is that?
My thinking is, there's often enough people working for a business that know what the problems are, and can figure out how to solve them. But they can't solve them if they don't have the authority to do so, or their superiors stop them, or nobody cooperates with their attempts. I don't know how to solve that, but it must have to do with agency and cooperation.
