A powerful pocket guide for practitioners that summarizes all research findings and materials from Otto Scharmer's foundational texts, Theory U and Leading from the Emerging Future. This book provides a concise, accessible guide to the key concepts and applications in Scharmer's classic Theory U. Scharmer argues that our ability to pay attention shapes the world. What prevents us from perceiving situations more effectively is that we are not fully aware of the inner state from which our attention and actions arise. Scharmer refers to this awareness deficit as our blind spot. He sheds light on the blind spot in today's leadership and offers practical methods to help change agents overcome it through the processes, principles, and practices of Theory U. Additionally, he outlines a framework for updating the operating systems of our educational institutions.
