Abstract: | We challenge the assumption that within-team variability in team efficacy is simply a methodological concern and statistical prerequisite. We do so by developing a theoretical model and research agenda for the study of dispersion in team efficacy. We construct a taxonomy that distinguishes 4 distinct forms of dispersion in team efficacy, discuss the antecedents to these forms of dispersion, and examine how the forms of efficacy dispersion impact team emergent states, processes, and effectiveness. |
