When people learn I’m a consultant, conversation often proceeds to problems and problem-solving. It’s true that I only get hired well after there is a problem. Typically a problem that has gotten so lousy that nobody wants to deal with it and it has therefore become worth the trouble—of spending time, money, effort, and reputation—to bring in somebody to sort it out. That said, I like ...
