Management is basically 99% people's relations/network. It doesn't matter how good the technical implementations are at the top, if they don't have the knowledge and capacity to enforce it downstream from middle layer to the base. There's so much people involved whose interests are farmed by your competitors.

Imposing it top down requires oppression. Imposing or pressuring this huge layer from the bottom requires a continuously updated base so you can squeeze from the top and the bottom to enact the changes needed quickly.

It's impossible for leaders at the top, to personally vet the members of a village or city council for example.

I think I've never seen any of such concatenation of events and organization to have ever happened.
