This cross-sectional study explored how IT system and software development team members communicated in the workplace and whether teams that used more verbal communication (and less text-based communication) experienced higher levels of collaboration as measured using the Teamwork Quality (TWQ) scale. Although computer-mediated communication tools (including email, instant messaging, text messaging, tweeting, and blogging) have been rapidly adopted and deployed in the workplace, the implications for team member interaction and performance are not well understood. Overreliance on text-based communication may impair team collaboration under certain circumstances. The results indicate that at least one of six facets of the TWQ construct is significantly related to greater use of the Textual Mode, and at least one facet is related to greater use of the Conversational Mode.
