I need you, you need me: a model of initiated task interdependence

The purpose of this study is to address two gaps in the existing literature. The first is why some team members have peers depend on them for material, information, and support (referred to as initiated task interdependence) more so than do others, ceteris paribus. The second is the appropriateness of initiated interdependence given a team's composition.

In an ex post facto field study, task interdependence in 267 members of 18 intact teams were examined. The teams worked on complex and inherently interdependent tasks in a high‐technology manufacturing organization.

Whether team members perceived initiated task interdependence was explained by the degree to which members themselves depend on their peers (received interdependence), team members' belief in the value of teamwork, and team members' self‐efficacy for teamwork. As predicted, both collectivism and past job performance were associated with self‐efficacy for teamwork. The relationship between initiated interdependence and individual effectiveness was moderated by the team's collectivist orientation, such that team members were considered relatively effective by their peers when they were high in initiated task interdependence and when their team was composed of collectivists; or when they were low in initiated interdependence and when their team was composed of individualists.

Although a one‐factor test suggests that common method bias is not an overriding concern in interpreting our findings, the possibility of common method bias inflating the associates tested cannot be rules out. Also, we cannot say with certainty that exogenous variables “caused” changes in endogenous variables.

Study findings suggest ways to resolve a lack of task interdependence and the importance of team composition when considering peer performance ratings.

This paper offers a significant contribution to the literature on task interdependence and person‐group fit.
