Book excerpt: A Multidimensional Approach to Leadership Top-down, one-dimensional leadership models are hopelessly outmoded in today's rapidly changing world, and they waste the leadership ability that is present throughout an organization. In this visionary book, Karen and Henry Kimsey-House provide a model that harnesses the possibility of many rather than relying on the power of one. Their revolutionary five-dimensional approach recognizes that leadership has to be fluid and flexible and that the roles leaders and followers play must shift to suit the situation. Co-Active Leadership invites all of us to share our expertise and allows collaborative solutions to emerge that would never have been possible otherwise.
