This study explores how team member familiarity is related to the communication media used in the completion of projects and how that use impacts project performance. We surveyed 148 university undergraduate students who were enrolled in information systems courses. The students worked on projects in teams of 3 to 4 students. The results suggest that prior collaboration with current te am members, as well as a stude nt’s class year, are related to what communication media are used. The influen ce of team member familiarity and class year varies by the type of media used. We also find that higher levels of text messaging are related to lower project performance. The results have im plications for practitioners and educators looking to enhance project performance.
