"Earth shakers figuratively shake the ground on which we work and live. They stir people to action to address tough problems. They mobilize people to fix what is flawed or broken. They generate movements to tackle complex issues. They transform teams, organizations, communities, and nations. They help us to think differently about the world, and to take actions to make it a better place. The earth shaker is a global change agent. They may operate at the local level or on the international stage but they appreciate how global forces and dynamics affect local forces and dynamics, and vice-versa. Given the interdependent nature of complex problems, they know they must cross borders and boundaries to get anything significant accomplished, as problems cannot be resolved in isolation. We need earth shakers because globalization presents a whole new set of challenges for which traditional forms of leadership cannot resolve. Globalization generates forces and dynamics that produce unintended and unexpected consequences—surprises—some that are delightful and some that are threatening and outright scary."
