Query: Useful even for the non-corporate among us

Even for an entrepreneur who doesn't have any full-time employees to speak of, this book is inspirational. Reading, for example, the 20 gold points of the Ritz-Carlton hotel organization offers up an ideal to emulate and would help any business-owner understand why some organizations are simply more pleasurable to deal with than others. I found several useful nuggets to incorporate into my own business environment. Definitely worth adding to the business bookshelf.
