A sociotechnical view of knowledge management is used to review the literature on knowledge sharing. Aspects of ownership and motivators for sharing knowledge are reviewed. It is only through the participation of Human Resources departments and individuals that the sharing of knowledge in organisations may succeed. Knowledge sharing is discussed and its barriers are addressed. A series of strategies are presented from four different contexts: social, organisational, managerial and technical. A discussion on how to develop a knowledge sharing culture is presented. One tool, Blogs, is discussed to formalise the knowledge sharing strategies implemented as a way to develop an organisational culture in which knowledge is shared.
