This research investigates how tacit knowledge is shared in an organization and how employees are involved in the internal marketing system by using the method of storytelling. The researcher focuses on a chain drugstore as a case to study, and attempts to explore how the organization takes advantage of storytelling to facilitate its internal marketing operation. Both semi-structured interview method and observation method are employed in this research. The study concludes a few findings that include: first, using storytelling as a method to facilitate internal marketing should not only develop anecdotic stories, but it also needs to strengthen the association among the abilities of communication, creation and learning. In other words, it is necessary to examine the capability of integration with organizational resources. Secondly, the development of story includes varied interactions which enable organizational value to be shared in the organization. Storytelling can then be viewed as a linkage between internal marketing performance and individual learning.
