I'm enjoying reading again the view of knowledge described by Ikujiro Nonaka and Hirotaka Takeuchi in their book The Knowledge-Creating Company. They posit that Japanese companies recognize knowledge to be primarily tacit, something personal and deeply rooted in an individual's actions and experience, in their ideals, values and emotions. Whereas the view "deeply engrained in the traditions of western management" is one of explicit knowledge, formally expressed in words and numbers, and easily communicated as hard data, scientific formulae or codified procedures. To the Japanese, apparently that's just the tip of the iceberg.
