This article explain a lot about what makes a great leader. Tomorrow’s leaders master three key roles — architect, bridger, and catalyst, or ABCs — to access the talent and tools they need to drive innovation and impact. As architects, they build the culture and capabilities for co-creation. As bridgers, they curate and enable networks of talent inside and outside their organizations to co-create. And as catalysts, they lead beyond their organizational boundaries to energize and activate co-creation across entire ecosystems. These ABCs require leaders to stop relying on formal authority as their source of power and shift to a style that enables diverse talent to collaborate, experiment, and learn together — a challenging yet essential personal transformation.
