An Alternative to the BOOK-TO-BILL?

摘要

Let me start by throwing down the gauntlet to the many protagonists of the book-to-bill ratio. Many PCB manufacturers have great faith in this technique, using it to make judgments that influence their business strategies. I would like to be contentious and suggest an alternative. Now, I agree that the book-to-bill is one form of a market indicator, if a rather crude one. However, I don't think that the book-to-bill analysis is particularly sensitive to long-term trends. It's something of a morale booster when the market is down and possibly a dangerous harbinger of disaster when the market is up.
