In , Bradley L. Kirkman and T. Brad Harris present a dynamic new model for maximizing team performance. Previous books have treated teams as groups of people working interdependently, an approach that overlooks two crucial components: the individuals who make up the team and the subgroups that form within and between teams. To create a fuller portrait of team behavior, Kirkman and Harris propose an innovative "3D" framework that takes into account all three factors. Drawing on their own research, best-in-class studies, and extensive consulting, they show leaders how to properly diagnose the state of their teams, hone in on the element that needs attention, and seamlessly shift focus among the three components of teamwork as time goes on. Delivering practical guidance rooted in scholarship, is a thoughtful and straightforward guide for the complex challenge of teaming today.
