15 Minutes Including Q&A: A Plan to Save the World From Lousy Presentations by Joey Asher
This book is strictly aimed at business presentations. For those, the approach must seem pretty radical: Your presentation should take no longer than seven minutes - the rest (of the 15 minutes) is for Q&A.
The author proposes a rather rigid format for those presentations. That's necessary, so that you can keep that time limit and also as a guideline for the presenter to cope with the requirements of this approach.
