This paper describes what we know about the effect of top managerial teams (TMT) size and diversity on the performance of new ventures and SMEs. It does so by summarising the results of a thorough literature search of quantitative studies published on this topic between 1990 and 2016 and of a meta-analysis on the relationships reported in these studies.
1990 and 2016 and of a meta-analysis on the relationships reported in these studies.
The search revealed 47 studies and 266 measured relationships between TMT size or diversity and firm performance. These studies employed different samples, econometric techniques, geographical and industry sector focus. Almost 77% of the studies in our sample focus on new ventures, 60% on high-tech firms and 36% on SMEs.
While the meta-analysis reveals many significant and positive effects of team size and diversity, the range of effects varies quite widely depending on context, generating a range of effect sizes from small to large. This inconsistency in results suggests that more replicative studies are required to add to the body of knowledge on team effects on performance.
