Scarce resources have facilitated increasing interdependence among organizations. This paper describes the group dynamics of the cooperation and collaboration models and examines which one is most suitable for maintaining effective group involvement. The cooperation model is comprised of two organizations that reach a mutual agreement; however, their work does not progress beyond this point. The collaboration model reduces conflict, diffuses power, promotes effective participation, and facilitates an abundance of rewards for each individual in the organization by eliminating the competitive, hierarchical arrangement found in the cooperation model. Despite the extra effort required, the collaboration model is argued to be most suited to the Western ideology of competitiveness. (LMI)
