In recent decades, the importance of knowledge management for an organization has been recognized by society, and managers are more likely to introduce it into management systems of their organizations, However, Wang and Noe (2010) asserted that the success of knowledge management initially depended on knowledge sharing, which was the foundation of communication between employees. Therefore, these questions will be raised as to what can influence knowledge sharing and how it can be influenced. This article will present a comparative review of two published studies, namely Knowledge sharing in a multicultural setting: a case study (Ford & Chan, 2003) and Knowledge sharing and team reliability: it's all about social connections! (Wang et al., 2006), the two authors answered the above questions on the basis of their studies. But even though both give us explicit conclusions and generally argue that knowledge sharing has a connection to social relationships, there are clear differences in the approach each takes to the study. Dr. Dianne P. Ford, who published in the Handbook on Knowledge Management, illustrates a result that cross-cultural difference is a barrier to knowledge sharing and there is a slight difference between intracultural knowledge sharing and cross-cultural knowledge sharing using case study and data analysis. (Ford and Chan, 2003) Dr. Wang and his colleagues seem to be more interested in the relationship between knowledge sharing and trust. They use the same methodology as Dr. Ford during their research to argue that trust plays an important role in knowledge sharing, but that it can also be replaced by social bonding and networking in some specific contexts. (Wang et al., 2006)This article is organized as follows.......middle of article......g the idea that when people meet someone they don't know , they don't talk too much, so there is little knowledge sharing. Unless after a while a belief relationship is established between them, they will share more knowledge. A link or social network, I think, is just a bridge to get people to meet others, but has not reached the high level of trust substitution. Same with Ford and Chan, Wang et al. also use case study methodology and data analysis. But unlike the previous ones which chose the best site for research, they use Wang's workplace, a technology research and development institution in Taiwan, as their study site. (Wang et al., 2006) Therefore, all studies focus on knowledge sharing within an innovation team, which is a certain component of the whole organization or society, significantly limits the scalability and extensibility of the results..
