1) Management hierarchies impose significant costs on organizations in the form of added overhead, risk of poor decisions, and slower responses due to more approval layers. They also systematically disempower lower-level employees.
2) While markets are effective for simple, stable interactions, they are less so for complex organizational activities that require coordination. Managers provide this coordination but do so inefficiently.
3) Self-managed organizations with no bosses or titles and where employees negotiate responsibilities with peers could provide an alternative, but transitioning an existing bureaucracy would require uprooting, not just pruning, existing structures and processes.
