Great book that teaches you how to structure a presentation based on a few simple but fundamental rules. Following Weissman's method, you are much more likely to put together a presentation that tells your story with a structured flow and is more likely to convince your audience. Additionally, these rules could be just as easily be applied to other forms of communications, especially where there is an element of persuasion required.
Please note that the author concentrates on the presentation rather than the presenter i.e. structure and flow rather than delivery techniques. I agree with this approach as effective delivery is down what he calls Verbalisation or simply practise, practise, practise.
In summary, highly recommended and I know I'll be reaching over to get it every time I have to prepare a presentation.
