TY - JOUR A1 - Fleischmann, Carolin A1 - Aritz, Jolanta A1 - Cardon, Peter T1 - Language Proficiency and Media Richness in Global Virtual Teams: Impacts on Satisfaction, Inclusion, and Task Accomplishment JF - ACM Transactions on Social Computing N2 - Virtual teams that use integrated communication platforms are ubiquitous in cross-border collaboration. This study explores the use of communication media and team outcomes—both social outcomes and task accomplishment—in multilingual virtual teams. Based on surveys from 96 virtual teams (with 578 team members), the research shows that the more time spent in rich communication channels, such as online conferences, increased inclusion and satisfaction, whereas the more time spent with written communication that is lower in richness increased the level of task accomplishment. Team members with lower language proficiency felt less included in all collaboration channels, whereas team members with higher language proficiency felt less satisfied with lean collaboration. In addition, limited language proficiency speakers were significantly less likely to view rich tools as helpful for their teams to reach a mutual decision. Our data support media richness theory in its original context for native and highly proficient English speakers. Our study extends the scope of the theory by applying it to the new context of team members with limited language proficiency. Management should implement a collaboration infrastructure consisting of communication platforms that integrate a variety of media to account for different tasks and different communication needs.
