It Takes Two to Make a Team Go Right

Today’s teams often have two formal leaders (i.e., dual leaders), yet research has almost exclusively examined the effects of a single, higher-level team leader’s behaviors on team members and team outcomes. This is problematic because these findings cannot unequivocally be applied to guide the use of dual-leader team structures. Using 93 professional service (i.e., audit) action teams, we examine effects of partner (i.e., external) and manager (i.e., internal) leaders simultaneously exhibiting initiating structure and individualized consideration leadership behaviors on team efficacy and, ultimately, team performance and team viability. Our findings show that the total capacity of leadership effects for a team with two leaders is only captured after considering the influence from both leaders simultaneously, especially when examining interactive effects between an individual leader’s behaviors and across two leaders’ behaviors. We find team efficacy is strengthened when the partner alone exhibits both higher structure and consideration, which is further augmented when the manager also exhibits higher consideration simultaneously. Thus, we find dual-leader interactions demonstrating the “Power of the Partner” and “Power of Consideration” effects are critical for building team efficacy, and in turn, team performance and team viability in dual-leader structures, revealing the existence of meaningful leadership interactions that cannot be found in single-leader studies.
