Decentralization makes your organization more agile and competitive. A decentralized organization is able to pivot and respond more quickly to changes in the market, laws, consumer tastes, and challenges compared to hierarchical, centralized companies.
Decentralized organizations are more stable than centralized ones. Centralized systems are overly dependent on one individual at the top calling the shots on everything. Remove them, and the entire system can collapse. Decentralized organizations have more broadly distributed leadership, making them more stable when there are leadership changes.
