For my vacation I grabbed a few handfuls of books from Bookdwarf’s office advance-review-copy pile. One of them was a business book by the editors of Business 2.0 Magazine. I read about ten pages of it and threw it across the room in disgust, because business books are all about teaching common sense and reason through anecdote and rule. If you are in your 30s and need a book to teach you how to handle facts like like “sometimes groups don’t cooperate well” and “customers hate it when you ignore them and lie to them” then it could be that you are a waste of oxygen and should be put to death.
On the other hand, here is a business thing that I have learned that may or may not seem obvious at first: your brochure is probably going to go unread, and if your customers read it, they won’t really read it carefully, because they will assume it has no useful information in it, and that it is full of vagueness. It probably is, in fact, devoid of the hard facts they need.
If you want them to consider your product, let them try it. An eval kit is worth 1000 flyers. A spec-sheet helps too, actually. People believe spec-sheets. Anything with too many adjectives gets tossed.
