Self-instructional handbook covers the practical how-to of preparing, setting up, and then presenting or demonstrating in front of the prospect. The third section of the book, on communications on multiple levels, covers the crucial issue of reading and sending the appropriate non-verbal messages, including positioning yourself and subtly moving the prospect. It also puts into context the overall purpose of demonstrations, presentations, proposals, free-trials, discounts and other special deals: to serve as proof sources, given for a specific, defined purpose that should be agreed-upon in advance with the prospective buyer. Unless the prospect is willing to make that up-front agreement, then it usually makes little sense for the sales person to proceed. How to gain and use that pre-commitment is covered in this book.
