Based on years of research and practical experience, Jeff DeGraff has learned that when it comes to any innovation initiative, disharmony is crucial. We innovate when we disrupt, and we first have to disrupt each other. DeGraff identifies four contrasting types of innovators. There's the wild experimentation of the Artist, the pragmatic caution of the Engineer, the urgent competitiveness of the Athlete, and the patient community building of the Sage. Exercises help readers find where they fit into this framework and show how to build, manage, and embrace the dynamic discord of a team with all four types. When you combine the visionary thinking of the Artist and the practical thinking of the Engineer, you get innovation that's both revolutionary and manageable, highly ambitious without high risk. When you combine the results-oriented attitude of the Athlete with the values-oriented attitude of the Sage, you get innovation that's both a good investment and good for the world.
