This study proposes that a shared organizational vision develops cooperative interdependence among departments that, in turn, facilitates cross-functional teams' organizational citizenship behavior (OCB). Team members indicated their organizations' shared vision, and leaders indicated the goal interdependence among departments and the OCB of the teams. Structural equation analysis suggested that a shared organizational vision shapes goal interdependence among departments that, in turn, affected the OCB of 101 cross-functional teams. The analysis suggested combining independent and competitive goals, and this combined measure negatively predicted team OCB. These results suggest that a shared organizational vision and cooperative goals among departments are important foundations for cross-functional teams to contribute to the effective working of organizations through citizenship behavior.
