Disc assessment is a tool used to understand how a person behaves, communicates, and responds to others. It measures four different types of behavior: dominance, influence, steadiness, and compliance. For each type, people can either be high or low in the trait. The assessment helps people understand how their behaviors affect each other, like how a dominant person may tell an influence-type person what to do, or how a steadiness-type person may offer support to a compliant person. Knowing these types of behaviors can help people understand how to interact better with friends, family, and colleagues, and also how to resolve conflicts.
