The document discusses knowledge creation in companies. It contrasts Western and Eastern/Japanese approaches to knowledge, finding that the Japanese approach taps into tacit knowledge like intuition and personal commitment. There are four patterns of knowledge conversion: tacit to tacit, explicit to explicit, tacit to explicit, and explicit to tacit. Knowledge spirals through these conversions as tacit knowledge is articulated and then internalized as more tacit knowledge. Honda provided metaphorical goals that allowed for individualistic and innovative car designs. For knowledge creation, companies should use metaphors, then analogies, and finally models, while also enabling redundancy and an ambiguous yet clear vision.
