Query: A great tool for work

As an earlier reviewer noted, this book isn't the DiSC in its purest form. However, it does provide a framework for understanding relationships at work clearly and concisely. I was introduced to the DiSC during a leadership school I attended through work, and this book provided me with the tools and framework I needed to share the model with my staff. In one-on-ones, I've been told that the process was both enlightening and useful on a daily basis.If you're looking for pure DiSC, look elsewhere. But if you want a tool to improve the way you and your staff interact, written in a way that's easy for everyone to understand, this is the book.
