The document summarizes research on the effects of narcissism on team dynamics. It finds that while narcissists can sometimes be effective leaders and motivated for success, they may also cause tensions through self-inflation and a self-serving bias. It recommends that managers acknowledge narcissists' contributions publicly, provide opportunities for self-enhancement to motivate them, and consider building teams with just one narcissistic member to avoid conflicts. Firms in turbulent markets are also advised to use an ego-centric network structure for teams.
