I just finished reading:

Powerful Questions That Highly Effective Business Leaders Ask: to build successful, dynamic, profitable organizations
Christo Norden-Powers (Author)
I'll post a review in a couple of weeks as its contents digest.
I wondered whether any MT members had previously reviewed or commented on it. It certainly fits with the MT style.
The author runs through numerous situations and actually gives you the words to use when asking questions to test or verify information. Includes coaching questions. It's one of the few books that I've implemented and got value from within days of reading.
Interested to hear others thoughts on the effectiveness of the techniques.
