It has been 25 years since the publication of a comprehensive review of the full spectrum of salesperformance drivers. This study takes stock of the contemporary field and synthesizes empirical evidence from the period . The authors revise the classification scheme for sales performance determinants devised by Walker et al. (1977) and estimate both the predictive validity of its sub-categories and the impact of a range of moderators on determinant-sales performance relationships. Based on multivariate causal model analysis, the results make two major observations: (1) Five sub-categories demonstrate significant relationships with sales performance: selling-related knowledge (β=.28), degree of adaptiveness (β=.27), role ambiguity (β=−.25), cognitive aptitude (β=.23) and work engagement (β=.23). (2) These sub-categories are moderated by measurement method, research context, and salestype variables. The authors identify managerial implications of the results and offer suggestions for further research, including the conjecture that as the world is moving toward a knowledge-intensive economy, salespeople could be functioning as knowledge-brokers. The results seem to back this supposition and indicate how it might inspire future research in the field of personal selling.Keywords Sales performance . Salespeople . Meta-analysis .

Knowledge-brokering An understanding of the factors that drive sales performance and how these vary across different contexts is essential for both managers and researchers in sales and marketing. Twenty-five years ago Churchill et al. (1985) published a seminal paper on the antecedents of sales performance that has shaped academic and managerial thinking on sales management and become one of the most cited articles in marketing research (Leigh et al. 2001). Applying a classification scheme of antecedents of sales performance developed previously by Walker et al. (1977), Churchill et al. (1985) found six predictive categories to explain marginal variance in sales performance (in order of predictive validity): role perceptions, skill levels, aptitude, motivation, personal characteristics, and organizational/ environmental variables. In addition, their meta-analysis demonstrated that the type of products sold moderated the predictive power of these categories for sales performance. Most empirical research thus far had been looking at enduring personal characteristics as determinants for sales performance. The basic message of this meta-analysis was that these variables were not the most important predictors (Churchill et al. 1985, p. 117). Instead, Churchill et al. (1985 suggested that researchers should investigate "influenceable" determinants of sales performance. Another key focus they proposed was the dynamic nature of the sales Mark. Sci.
