Diverse Work Groups and Employee Performance

Abstract

This study is a report of an investigation of group diversity—particularly informational diversity and social diversity—revealing its effects on individual performance through communication ties. Two studies, one using 127 groups of employees from six firms and another using 104 groups of part-time students from a training program, demonstrate that informational diversity affects individual task and creative performance through communication ties, whereas social diversity does not. Future research and practical implications are discussed.
