The SECI model of knowledge dimensions (or the Nonaka-Takeuchi model) is a model of knowledge creation that explains how tacit and explicit knowledge are converted into organizational knowledge. The aim is to change the explicit knowledge of the model back into the tacit knowledge of the employees.[1] In this case, employees' tacit knowledge can be kept in the organization. When employees express their thoughts and ideas openly and share their best working practices, it can lead to new innovations and help to make operations more efficient.[1]
The SECI model distinguishes four knowledge dimensions (forming the "SECI" acronym): Socialization, Externalization, Combination, and Internalization. The model was originally developed by Ikujiro Nonaka in 1990[2] and later further refined by Hirotaka Takeuchi.[3]
