Integrating the open systems perspective of groups and the contingency approach to diversity, we study how group diversification (i.e., a process in which a group becomes more diverse over time as members join and/or leave the group) affects group performance change in an adverse task environment. We argue that diversification benefits performance by reducing group performance decline in times of adversity. Group size increase, however, attenuates this preventative benefit of group diversification. Focusing on organizational tenure and gender, we studied 279 sales groups (3277 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 (conditional) beneficial view of diversity from a static theoretical space about group being diverse to a dynamic one about group becoming diverse.

团队多元化对团队绩效下降的预防益处：潜在增长模型的调查

结合开放系统的群体观点和采取权变方法的多样性，我们研究了群体的多元化（即随着成员的加入和/或离开群体，群体随着时间的推移而变得更加多样化的过程）如何影响不利条件下的群体绩效变化。任务环境。我们认为，多元化可以通过减少逆境中的团队绩效下降来使绩效受益。但是，团体人数的增加削弱了团体多元化的这种预防益处。我们着眼于组织结构和性别，在2004年至2008年期间研究了一家大型德国金融咨询公司中的279个销售组（3277个个人）。在此期间，国家立法变更促使该公司退出市场上的明星产品，并带来了逆境到销售组。潜在增长模型（LGM）的结果总体上支持了我们的论点。这项研究从关于群体的静态理论空间扩展了多样性的（有条件的）有益观点。成为一个充满活力的，关于群体变得多样化的人。
