Self-administered questionnaires, document review and personal observation were used as data collection techniques. The survey was conducted online with KwikSurveys tool. The method of analysis was a low level analysis as the basis for the findings. The study concluded the significance of understanding and managing culture differences to the knowledge sharing and collaboration in cross-cultural teams. The paper also investigated how communication is enabler of knowledge sharing. The research result furthermore showed rate of utilization of collaborative tools and its preference by EY staffs by making use of Technology Acceptance Model (TAM) model.

Finally, the researcher recommends that multinational firms can win the battle of developing a true knowledge sharing and collaboration culture by working as a unit, reducing cultural distances and tackling barriers.encommunication, national culture, knowledge sharing, multinational organization, knowledge sharing barriers, Technology Acceptance Model and collaborationThesis
