Risk Based Thinking

Twenty years ago, we wrote 4 best selling, ISO 9001 books. They were fun times. Quality was Job #1. W. Edwards Deming, Joseph Juran, Phil Crosby, and other quality gurus were considered quality management and general management authorities. We would give a quality or ISO talk and then walk away with 1 or more clients.
So why are we writing another book on quality and replowing a topic that has been written about extensively? The challenge is there is little information on Risk Based Thinking (RBT) addressing ISO 9001:2015 and ISO other management system standards. ISO: Risk Based Thinking is the first book on RBT and operational risk. This book in its second edition is the first update.
