This article examines the influence of heterogeneity within a sales unit on the unit’s satisfaction and performance. Sales unit refers to a set of salespersons working out of the same office and for the same supervisor, and heterogeneity refers to salespersons’ dispersion or variance on key dimensions. Specifically, drawing on theories in social psychology, the authors study the influence of sales unit heterogeneity in terms of (1) demographic characteristics (e.g., gender dispersion), (2) skills and rewards (e.g., reward dispersion), and (3) goal orientations (e.g., learning orientation dispersion) on a sales unit’s performance and job satisfaction levels. The hypotheses developed are tested using data from a study involving 476 salespeople belonging to 105 sales units in a large organization. The authors find that the focal heterogeneity variables account for nearly 25 percent of the total variance explained by the full set of independent variables included in the model.
