Knowledge sharing is an activity through which knowledge (i.e. information, skills, or expertise) is exchanged among people, friends, co-workers, or members of a family, a community (e.g. Wikipedia) or an organization.
Organizations have recognized that knowledge is a valuable asset for competitive advantages. Knowledge sharing activities are generally supported by knowledge management systems. However, technology is only one of the many factors that affect the sharing of knowledge in organizations. The sharing of knowledge constitutes a major challenge in the field of knowledge management because some employees tend to resist sharing their knowledge with everyone else.
One obstacle is the idea that knowledge is property and ownership. In order to counteract this, individuals must be reassured that they will receive some type of incentive for what they create. Risks in knowledge sharing are that individuals are most commonly rewarded for what they know, not what they share. If knowledge is not shared, negative consequences such as isolation and resistance to ideas happen. To promote knowledge sharing and remove knowledge sharing obstacles, the organization should encourage discovery and innovation.
