Rea's book appears to be written for those not yet in training. The book covers all the topics that trainers will be interested in but left me unsatisfied. When I finished the book it confirmed that the questions I was seeking answers to where pretty much the full, correct set of questions, but mostly, beyond common sense, it offered no insight. Worse in places it was deeply frustrating.
As an example: Just how do you conduct attendee intros ? The book confirms the problems of personal "creeping death" and randomly choosen introductions, buddy intros, team circulation intros. Then says there are more exercises of this type than you can dream of on the internet - but not the slightest hint of where to look. There were upward of half a dozen places where material is either irrelevant ( eg 19 steps to make a cup of tea as illustration of how inadequate some one-2-one training is) or a reasonable description of the problem/opportunity with inadequate description of the theories or practices used to dealing with the topic ( eg communication may fail due to barriers of language, speech, psychology: answer be an expert and talk clearly, find out what is irking them !)
In conclusion: of 178 pages about 12 are really good, 12 really bad and the rest lacked enough for me to feel they warranted the cover price.
