This paper delves into the relationship among the organizational culture, team creativity and team
work performance and looks into the influences of the underlying factors of the organizational culture
on the team creativity. Studies of this kind have been done for administration and manufacture
industries, but, little research has been done for the advertising industry or advertising agency
employees. A survey was done to test the theoretical hypotheses on a large advertising agency's workers
in Seoul. As results, three out of four organizational culture factors show positive relationship with
team creativity as they are the case for the other industry studies, but, one factor, hierarchial culture
does not affect the team creativity which is not in line with the study results of relevant literature for
other industries. The results suggest that like unity, autonomy, interaction, the ad company
organization's flexibility plays an important role in fostering team creativity like other industries. It is
also suggested that, in an advertising agency, team creativity is affected more by internal reasons than
external environmental ones of the work. More implications and research suggestions are presented in
the discussion.
