Feedback behavior is key factor for developing an individual and team"s competitive advantage. Therefore, organizational members need to focus on proactive feedback activities to improve individual and team performance. This study conducted a multi- level analysis to find out the antecedent and consequence of feedback behavior. At the team level, the relationship of the feedback climate of the team was investigated in the relationship between authentic leadership and the creative performance of the team. At the individual level, the effect of feedback behavior was examined in the relationship between radical candor and in-role & extra-role performance. The 81 teams (328 employees) were chosen from employees of 42 companies in South Korea. Our empirical analysis confirmed at the team level, that the feedback climate of the team partially mediated the relationship between authentic leadership and the team creative performance. Meanwhile, at the individual level, it was observed that the feedback behavior was fully mediated the relationship between radical candor and in-role & extra-role performance. Based on the research results, theoretical and practical implications were presented.
