This study identified several group characteristics from group composition and process perspectives and examined their relationships with group performance over time. A longitudinal laboratory experiment was conducted to evaluate influences of preference for group work and perceptions of heterogeneity, group potency, and outcome expectation on performance of 31 student work groups performing decision-making tasks. Results of partial least squares analysis indicated that preference for group work and perception of group potency were the strongest predictors of group performance at both Time 1 and Time 2. These variables were found to be stable over time. Results also indicated that group members' perception of outcome expectation were reinforced by their groups' initial performance. Implications of these results for implementing group-based work systems and conducting group research are discussed.
