Hal,
And therein lies the problem, the "rush" factor. Being the first book on a topic, but a poor quality one, IMHO, is worse than being a little late and top shelf. Why? Because you drive repeat customers away with a second rate product. The more reliable product will keep consumers coming back for more.
This is exactly how my company used to release software, rush it out the door, and it was buggy. Our customers were initially elated to get the new features, but then the elation turned into anger when reliability went down the tubes. In some cases we lost the customers all together. Well, my boss got the message and went to a TQM model and things have been better. Not perfect, but much better.
Obviously you cant wait an extra 6 months to a year to release a book because by then the subject matter is probably out dated. But, isn't an extra 6 - 12 weeks possible to get it right?
