Disasters and the initial push of any war show what is possible. Like the playbook is already know. Strict hierarchy with decision making power at the bottom. This may sound contradictory, sure.

However, it works like this: the top sets a goal, the bottom decides how to get it done. Person closest to the problem then leads.

We know it works. It happens every time a large group -needs- to use it.

However, as soon as things get stable, large orgs go right back to rigid central control.
