William Moulton Marston defined the four quadrants of personality as Dominance, Influence, Steadiness, and Compliance, which we still use in DISC Personality Tests today. However, the History of DISC doesn't come to its present until 1940. In 1940, Walter Clark took the theory of William Moulton Marston and developed the first DISC Personality Profile. The Same DISC Personality Profile that is still in use today!
At Innotrek, we use the DISC profiling system from IML and design programs for participants to better understand their behaviors and how to work with others.
