Book excerpt: Every so often a book comes along with a brand new, innovative and startling approach to an everyday subject. On the subject of business communication, that book is The Hidden Profit Center. While most business leaders agree--without much real thought-- that communication is important, author Helen Wilkie contends they have no idea just how important. In fact, when people communicate ineffectively at work, it costs companies money. Real, hard dollars-- and lots of them. Inspired by books like "The One Minute Manager and "Who Moved My Cheese?, Wilkie has written a deceptively simple fable that makes the shocking cost of poor communication unmistakable. Written for busy people, this small but invaluable book can be read in less than two hours--perfect for a business flight.
