Started with tables creating maps for the nation of "KM". My thinking was an island chain in the pacific "Ring of Fire". New, fertile earth, beset by natural disasters outside of the nation's control. Newly formed volcanic peaks, rules for what happens when a lava flow claims your golf ball. Small tribes living in partial isolation, under threat of colonisation from the large, powerful management nations of Finance and Management, maligned by the newly powerful IT nation. Picture Vanuatu with a lot more nerds.
Matt then asked everyone to describe other nations that interact with the KM nation. As you can tell from above, I (and others) skipped ahead and started defining that. I also think there is a strong relationship between the nation's of Strategy and Learning, although these more established consist of populations that are ignorant of KM to a greater or lesser degree, as the population of KM is of them.
Think I got slapped down for my suggestion that nothing is outside of KM as a discipline. Tough. Its not a nice answer, but it is right, and artificially constraining the domain because not doing is too hard is only damaging in the long run. Sorry, Matt.
