團隊即興是一種團隊成員面對無前例的挑戰時，能經由快速的討論與互動所產生多元性新構想的能力，此種模式源自於爵士樂的臨場創作並將其精神運用在管理學界。過去研究提到這類即興團隊，成員能更主動、即時地展開行動，且團隊成員較不會框架自己的想法、思考，亦能激發團隊創新想法，使其提升團隊創造力，因此團隊即興對於團隊創造力應有正向影響。本研究發現過去探討團隊關係品質對團隊即興與團隊創造力間關係的影響研究甚少且檢視過去文獻團隊成員間的關係應會對團隊即興與團隊創造力間關係產生中介作用。本研究採用實驗研究的方法，研究對象是高中一年級共638位學生，依各班人數規模共分成117組團隊，如此較能控制其他因素的干擾，也較能瞭解彼此間的實際關係為何，以提供後續研究之參考。研究結果發現，團隊即興正向影響團隊創造力，而團隊即興與團隊創造力中間透過團隊成員關係品質所影響。當團隊展現高度即興風氣，表示團隊成員間信任度高，成員間關係也非常密切，也就是說團隊即興對於團隊關係品質有正向影響，這對未來後續進行團隊即興的研究有參考的價值。

Team improvisation is an ability of team members to develop diversified new ideas through quick discussions and interactions when facing unprecedented challenges. This method applies the essence of jazz improvisation in the field of management. Previous studies had mentioned members of this kind of improvisation teams can take actions more actively and promptly. And these members are less likely to limit their ideas and thoughts. Team improvisation helps team members to come up with new ideas and facilitates improvements in team creativity. Thus, there should be a positive influence of team improvisation on team creativity. This study found that there have been only a few studies on the influences of team relationship quality on team improvisation and team creativity and inferred based on previous literature that there should be mediating effects of relationships among team members on team improvisation and team creativity. Thus, this study adopted the experimental research approach with 638 high school freshmen as research subjects who were grouped into 117 teams according to the number of students in each class for the purpose of avoiding interferences from other factors and exploring the real associations among the factors in question, to provide references for future research. The results of this study showed a positive influence of team improvisation on team creativity and a mediating effect of team relationship quality between team improvisation and team creativity. When improvisation takes place very often in a team, it means that the trust among the members of this team is strong and the relationships among those members are very tight. In other words, team improvisation may positively affect team relationship quality. The value of these findings as references for future research on team improvisation is high.
