The 2,000-plus businesswomen who will gather at this conference (June 23-26) are serious about networking -- featured prominently on the timetable are MatchMaker Meetings, a sort of speed dating for companies. They're also serious about business, if the keynoter is any sign. Chin-Ning Chu, author of The Art of War for Women, will teach attendees how to apply The Art of War, the famed sixth century B.C. military treatise by Sun Tzu, to the workplace. As conference cochair Nancy Williams explains, Chu's focus will be "understanding your competitor, who is your enemy," because "going into business is like going into war."-- BB
