Over the last couple of years, I have become interested in adapting techniques from improv theatre to organizational training settings. Koppett's book helped me solidly solidify my thinking on the matter. She divides her book into two sections, Principles and Activities. The Principles section is broken into seven chapters that address trust, listening and awareness, non-verbal communications...all the kinds of things for which organizations seek training. The Activities sections has instructions for 50 activities, including an overview, the relevant principles, instructions and variations, and even questions that facilitate discussions after the activity is complete. For added value, the appendices break each activity down into improv principles (trust, spontaneity, etc.) or training application (team-building, creativity, problem-solving, etc.) I've used this resource dozens of times already. In fact, I've had trouble getting it back from several colleagues, and don't lend it out anymore!
