SECI, Ba and Leadership: a Unified Model of Dynamic Knowledge Creation. Long Range Planning Vol.33 No.1 pp.5-34

Despite the widely recognised importance of knowledge as a vital source of competitive advantage, there is little understanding of how organisations actually create and manage knowledge dynamically. Nonaka, Toyama and Konno start from the view of an organisation as an entity that creates knowledge continuously, and their goal in this article is to understand the dynamic process in which an organisation creates, maintains and exploits knowledge. They propose a model of knowledge creation consisting of three elements: (i) the SECI process, knowledge creation through the conversion of tacit and explicit knowledge; (ii) 'ba', the shared context for knowledge creation; and (iii) knowledge assets, the inputs, outputs and moderators of the knowledge-creating process. The knowledge creation process is a spiral that grows out of these three elements; the key to leading it is dialectical thinking. The role of top management in articulating the organisation's knowledge vision is emphasised, as is the important role of middle management ('knowledge producers') in energising ba. In summary, using existing knowledge assets, an organisation creates new knowledge through the SECI process that takes place in ba, where new knowledge, once created, becomes in turn the basis for a new spiral of knowledge creation.

A firm as a knowledge-creating entity: a new perspective on the theory of the firm. Industrial and Corporate Change Vol.9 No.1 pp.1-20

More

The knowledge-based view of the firm views a firm as a knowledge-creating entity, and argues that knowledge and the capability to create and utilize such knowledge are the most important source of a firm's sustainable competitive advantage. Knowledge and skills give a firm a competitive advantage because it is through this set of knowledge and skills that a firm is able to innovate new products/processes/services, or improve existing ones more efficiently and/or effectively. The raison d'être of a firm is to continuously create knowledge.
