Transforming Individuals into Groups: Some Hallmarks of the SDS Approach to Small Group Research.
During the past 25 years, Davis's social decision scheme (SDS) model, designed to clarify how individual-level characteristics combine to create group-level products, has had a major impact on small group research. Using formal, mathematical models, Davis and his colleagues first construct predictions, or theoretical baselines, about group products based on assumptions about members' characteristics and interactions and then compare these predictions to the performances of real groups. The SDS approach has been valuable in clarifying how group performance is affected by such variables as task characteristics, group size, individual differences (e.g., member status), procedural factors (e.g., straw polling, agendas), and temporal changes in social parameters.
