From the Cluetrain Manifesto (theses #49-52), because this stuff is still relevant:
"Org charts worked in an older economy where plans could be fully understood from atop steep management pyramids and detailed work orders could be handed down from on high.
Today, the org chart is hyperlinked, not hierarchical. Respect for hands-on knowledge wins over respect for abstract authority.
Command-and-control management styles both derive from and reinforce bureaucracy, power tripping and an overall culture of paranoia.
Paranoia kills conversation. That's its point. But lack of open conversation kills companies."
