Nonaka, I., & von Krogh, G. (2009). Tacit Knowledge and Knowledge Conversion: Controversy and Advancement in Organizational Knowledge Creation Theory. Organization Science, 20(3), 635-652.

Paper builds on Nonaka’s paper (1994, a dynamic theory of organizational knowledge creation) and discusses research made based on the ideas presented in the paper 1994. It validates findings made in the earlier paper, but also adds conclusions about outcome of knowledge conversion. It should lead to product and process innovations, enhanced capacity to act, and enhanced capacity to define and solve problems. One interesting idea presented from research made in the field is that tacit knowledge is not tacit knowledge if it can be transferred and explicit knowledge is not knowledge if it is explicit since it has become information.
