Tacit knowledge can be defined as skills, ideas and experiences that people have in their minds and are, therefore, difficult to access because it is often not codified and may not necessarily be easily expressed (Chugh, 2015).[2] With tacit knowledge, people are not often aware of the knowledge they possess or how it can be valuable to others. Effective transfer of tacit knowledge generally requires extensive personal contact, regular interaction[3] and trust. This kind of knowledge can only be revealed through practice in a particular context and transmitted through social networks.[4] To some extent it is "captured" when the knowledge holder joins a network or a community of practice.[3]
