Final answer:
Among the provided options, having a devil's advocate is not a deterrent to successful teamwork; instead it can encourage critical thinking and help teams avoid conformity and groupthink.
Step-by-step explanation:
The question revolves around identifying which option is not a deterrent to successful teamwork. when exploring factors that may inhibit the effectiveness of a team, it is important to consider elements such as poor communication, individual motivations that are at odds with the group and the presence of social loafing. however, not all factors are negative. for instance, having a devil's advocate in a team can be beneficial.
While competition between teams, leaders without motivational skills, and a cultural emphasis on individualism can be significant roadblocks to team success, the role of a devil's advocate is often to provoke critical thinking and help the group avoid groupthink, thereby enhancing decision-making.
