For the past 30 years I have been working with the DISC system of behavior in training, consulting and coaching applications. I've had the opportunity to use the DISC system  with over 30,000 people in seminars and workshops in a great variety of industries, organizations and countries.  I've also had the opportunity to develop several products based on the DISC system of behavior-DiSC �PPSS, DiSC� Indra™, Role Behavior Analysis�, and DiSC� Management Strategies. As a result of my work as a DISC practitioner and my continued involvement in the research and development of the DISC system, I've had a chance to dig really deeply into the history of the DISC model of behavior and into the underlying  structure of the DISC system.

Since the early 1990s when I initiated the revalidation of DiSC� Classic, I have been wrestling with questions about the underlying structure of DISC.  During my 20-year literature search on the history of DISC, I discovered not only the historical roots of the DISC system but also where the DISC system fits in the field of personality and temperament. It is the confluence of these two areas of practice and research that resulted in the breakthrough idea that DISC is round. This wildly exciting "Eureka" moment occurred in the fall of 2002 while I was developing DiSC� Indra™. Since that time, I have had the opportunity to continue to develop more understanding of the application of DISC-in-the-Round which I'd like to share with  you in this newsletter and in future training events.
