The DISC Personality System published by the Institute of Motivational Living (IML) aims to help individuals identify their personal strengths and capitalize on their talents to make them more effective individuals.

In identifying one's own and others' innate abilities, attributes, weaknesses and fears, the DISC helps people communicate better and work together more effectively. The concept of the DISC is based on William Marston’s theories, which postulate that people basically possess one or more of four different personality styles:

• Dominance - direct, decisive, a problem-solver, a risk taker and a self-starter 

• Influence - enthusiastic, trusting, optimistic, persuasive, talkative, impulsive and emotional 

• Steadiness - a good listener, team player, possessive, steady, predictable, understanding and friendly 

• Compliance - accurate, analytical, conscientious, careful, precise, meticulous and systematic.
