Training to Imagine is the definitive guide to using improvisational theater techniques to enhance creativity, teamwork, leadership, and growth in professional settings. This third edition explores the principles of improvisation—trust, spontaneity, accepting offers, listening and awareness, storytelling, and presence—and demonstrates how they can be applied to real-world situations. Koppett includes updated research on the value of improvisation, fresh examples, detailed activity design flows, and over 50 activities that can be used for individual self-development, small groups, and organizational development. This edition has been updated to more explicitly tie improv principles to building inclusive environments, supporting diverse voices, and creating connection and community, ideal for both higher education and organizational contexts. Leaders, educators, and facilitators interested in using improv to strengthen their interpersonal skills will find immense value in this book.
