DiSC is a behavioral profile that has helped more than 40 million people around the world become more effective in their interpersonal relationships. DiSC is a tool that analyzes your behavioral style in a work environment. Your DiSC profile will help you understand how you project yourself to different people in different situations, so you can develop strategies to meet the needs of the situation, culture and individuals. Behavioral research suggests that the most effective people are those who understand themselves—their strengths and weaknesses—so they can develop strategies to meet the demands of their environment.
