Taking the open systems perspective, we define group diversification (homogenization) as a process in which a group becomes more (less) diverse over time as new members join and/or existing members leave the group. Building upon the contingency approach to diversity and group adaptation literature, we argue: In an adverse task environment characterized with unexpected changes and ill-performing risks, group diversification benefits group performance change by reducing group performance decline in this environment. Group size increase, however, attenuates this preventative benefit of group diversification. Focusing on organizational tenure and gender, we studied 279 sales groups (3,277 individuals) in a large German financial consulting company from 2004 to 2008. In this period, a national legislative change prompted the company to withdraw its star product from the market and presented adversity to the sales groups. Results from latent growth models (LGMs) overall support our arguments. This research extends the beneficial view of diversity from a static theoretical space about groups’ being diverse to a dynamic one about groups’ becoming diverse.
