SECI model of knowledge dimensions

The SECI model of knowledge dimensions is a model of knowledge creation that explains how tacit and explicit knowledge are converted into organisational knowledge. The SECI model distinguishes four knowledge dimensions – socialization, externalization, combination, and internalization – which together form the acronym "SECI". The SECI model was originally developed by Ikujiro Nonaka in 1990 and later further refined by Hirotaka Takeuchi.
