Proven Principles To Help Engage Your Team & Improve Performance

By Chris Rollins and featuring insights from leading human behavior experts. 

DISC is a model of human behavior. It is far more than merely an assessment that someone takes. Learn from the experts who share their personal experiences on how to actually apply this model to significantly impact your team's performance. 

Human behavior is predictable, but it doesn't have to be labeling either. This book isn't filled with academic theory, but explains real-world application to apply this in your daily life.
