This book, written by leading experts in the field, is intended for thoughtful leaders, advisors, and academics who want to better understand cutting edge thinking and the latest research on leadership in the complex, highly interconnected organization of today. Unlike most books on the subject, it does not purport to provide simple answers to difficult questions. Rather, it seeks to provide new insights and tools that have only recently become apparent through advances in complexity science-like, for example, the intricate dynamics of emergent leadership as simulated through agent-based modeling (ABM). Complex Systems Leadership Theory is a powerful beginning to what promises to be a deeper, more thoughtful investigation of how and why organizations succeed and what leaders can do to make a difference.
