Ikujiro Nonaka and Hirotaka Takeuchi propose a model of the knowledge creating process to understand the dynamic nature of knowledge creation, and to manage such a process effectively: the SECI model.
There is a spiral of knowledge involved in their model, where the explicit and tacit knowledge interact with each other in a continuous process. This process leads to creation of new knowledge. The central thought of the model is that knowledge held by individuals is shared with other individuals so it interconnects to a new knowledge. The spiral of knowledge or the amount of knowledge so to say, grows all the time when more rounds are done in the model.
