기능적 다양성이 팀창의성에 미치는 영향: 팀 내재적 동기부여의 매개효과와 과업 상호의존의 조절효과를 중심으로

Many creativity researchers have examined the effects of functional diversity on individual and organizational effectiveness. Of these various outcomes, creativity has received an increasing attention from management scholars because it is critical for organizations to survive and sustain organizational success in the long run under radical changes in business environments. Although current studies on functional diversity have enhanced our understanding the effects of functional diversity on individual and team creativity, there are several important issues that need to be addressed. First, there is lack of studies that examined the underlying mechanisms that link between functional diversity and creativity. Second, there is limited studies on the conditional factors that can mitigate or enhance the relationship between functional diversity and creativity. Third, most studies on functional diversity have been done in the Western society. It would be interesting to examine whether the current findings in the Western countries can be generalized to Asian contexts(e.g., South Korea) where social norms and principes in interpersonal relations are different from those in the Western society. Our study aims to examine how team functional diversity affects team creativity, how team intrinsic motivation mediates the latter relationships, and how task interdependence moderates the relationship between functional diversity and team intrinsic motivation. To address theses issues, we collected the data fromeight Korean companies(i. e., two high technology manufacturing companies, two software development companies, two pharmaceutical companies, and two promotion companies). We distributed 354 supervisor-subordinate pair surveys. To avoid common method bias, we asked subordinates to assess their functional backgrounds, team intrinsic motivation, task interdependence, and asked supervisors to assess their functional backgrounds and team creativity. We used 269 complete supervisor-subordinate pairs in the analyses, and found that functional diversity was positively associated with team creativity. Also, we found that team intrinsic motivation significantly mediated the relationship between functional diversity and team creativity, and task interdependence moderated the latter relationships. We discussed several theoretical and practical implications of the findings.
