In today's fractured world, collaboration is increasingly difficult yet more crucial than ever. Often, to get something done that really matters, we need to work with people we don't agree with, like, or trust. Drawing from thirty-plus years of experience working with leaders in over fifty countries, Adam Kahane shows why conventional collaboration—requiring harmony and agreement—is obsolete. Instead, he provides a groundbreaking approach that embraces discord, experimentation, and genuine cocreation. Kahane introduces three key stretches to navigate difficult collaborations: ● Stretch to embrace conflict and connection ● Stretch to experiment and learn ● Stretch to step into the game This substantially revised second edition adds multiple new chapters exploring how to work across deepening divides and with those we may never agree with. Using new case studies, a discussion guide, and frameworks for navigating permanent plurality in our polarized times, Kahane offers essential tools for transforming conflict into positive change.
