Humor can positively impact many aspects of project management. It can improve communication, aid in team building, help detect team morale issues, and influence leadership, conflict management, negotiation, motivation, and problem solving. While humor has benefits, it also has risks and not all uses of humor are positive. Future research is needed on humor in multicultural teams, its relationship to team performance, how humor is learned, and determining optimal "doses" of humor. In conclusion, humor is a tool that can influence people and projects, but must be used carefully and spontaneously for best effect.
