This chapter reveals the overview of knowledge transfer; knowledge transfer, labor mobility, and labor diversity; knowledge transfer and subsidiary perspectives; barriers to knowledge transfer; knowledge transfer and absorptive capacity; knowledge transfer and knowledge acquisition; knowledge transfer and virtual teams; and the advanced issues of knowledge transfer in modern organizations. The process of transferring knowledge is an ongoing progression of learning, adjusting, and improving. At the organizational level, knowledge transfer manifests itself through changes in the knowledge of a unit. Most successful knowledge transfer efforts actively involve both the source of the knowledge and its receiver. Establishing performance expectations for those who will use the knowledge further quantifies the value of the transfer. Companies considering or using knowledge transfer processes, should continuously evaluate their social media readiness. The benefits of knowledge transfer for workplaces include the increases in productivity, speed, agility, profits, and growth.
