This method is called the DISA—an acronym that stands for Dominance, Inducement, Submission, and Analytic ability—system. These four terms are the primary behavior types, which describe how people sees themselves in relationship to their environment. Each of these behavior types is associated with a color—Red, Yellow, Green, and Blue. This system is also commonly called the DISC system, where the final letter of the acronym stands for Compliance instead of Analytic ability.
