This document provides an overview of the DiSC assessment tool. It describes DiSC as a snapshot of preferences that helps understand strengths and limitations for building relationships, but is not meant to label people. The four DiSC preferences - Dominance, Influence, Steadiness, and Conscientiousness - each have different motivations and potential limitations. The document encourages using DiSC to communicate more effectively while meeting others' needs, rather than labeling people.
