At the recommendation of my UCLA communications professor, I read Buy-In: Saving Your Good Idea from Getting Shot Down by John Kotter. It was a fun, quick read and great preparation for the Q&A section of a presentation competition I'm a part of right now.
The book begins with a story of a committee that comes up with a great plan to supply new computers at no extra expense to the local library. First, a variant of the story is presented with the leader "winging" his presentation and resulting Q&A. Then, a "better" way is illustrated, showing how many common types of attacks can be handled in order to generate real "buy-in" from an audience.
Below are some of my main takeaways from the book. A full list of the 24 most common types of attacks and recommended responses is online.
