This research describes how the enabling factors influence knowledge sharing in Indonesia. The samples are 267 employees from three different companies in Indonesia. The results of this research show that knowledge sharing has been well implemented in the three companies. The enabling factors that influence knowledge sharing are at the individual, organisational and technological levels. Among them, the technological factor is found to be the strongest. Employees in Indonesia are very cooperative and helpful in the implementation of knowledge-sharing activities. Although the rewards from the organisation are not high enough, knowledge sharing activities are still very well conducted. In order to increase knowledge sharing activities, more concern and appropriate follow-up are needed, especially with regards to technological factors.
