What is Tacit Knowledge Taxonomies

Many researches have treated the knowledge management theory. However, to the authors' knowledge few were interested in the tacit knowledge construct, whether it is gained inside or outside the organization. This chapter has a challenge to analyze in-depth this embedded knowledge and to emphasize its close relationships with innovation management. Therefore, a thorough theoretical background is presented progressively. The first part presents an overview of the knowledge notion, and the related knowledge theoretical views are specified. The second part sheds light on the tacit knowledge's taxonomies and its methods of externalization. Finally, the last part examines, in particular, the contribution of the tacit knowledge to the innovation. This is done by scrutinizing the customer tacit knowledge while highlighting, especially, the key role of customer experiential knowledge.
