This document discusses complexity-based leadership and navigating adaptive challenges. It provides an overview of complexity thinking and adaptive leadership. It discusses that adaptive challenges require generating and trialing multiple solutions as they are embedded in social complexity, compared to technical problems which can be solved with existing knowledge. It also discusses fostering collective intelligence through mechanisms like cross-functional teams to engage stakeholders and generate better solutions. Finally, it discusses that adaptive change processes are cyclic with multiple experiments compared to linear change processes for technical challenges.
