Harmony is sublime in music but deadly to innovation. The only way to create new, hybrid solutions is to clash. Innovation happens when we bring people with contrasting perspectives and complementary areas of expertise together in one room. We innovate best with people who challenge us, not people who agree with us. While that may sound like a recipe for chaos and confusion, the DeGraffs introduce a simple framework to explain the ways different kinds of thinkers and leaders can create constructive conflict in any organization. They argue that this positive tension produces ingenious solutions that go far beyond the best of both worlds. Using vivid examples, the DeGraffs offer four steps to normalize conflict and channel it. Their rigorous but highly accessible guide can help you achieve breakthrough solutions by utilizing all four types of innovative thinkers-the Artist, the Engineer, the Athlete, and the Sage-together.
