Leadership combines art and science and as we peel back the complexity of global leadership, we begin to recognize the complexity of the art and the science. Leading in Complex Worlds is a scholarly and practical treatise of the multifaceted, multidimensional, multidisciplinary, and multicultural aspects of leadership in a global world and, perhaps more significantly, within ourselves as we engage in the leadership dance of art and science.
