Scientific Background
DISC was developed by psychologist William Moulton Marston in the 1920s and later refined into a structured assessment tool. It focuses on how a person behaves in their environment — not on deep personality traits — making it especially useful in professional settings for improving communication, delegation, and conflict resolution.

Frequently Asked Questions
- What does DISC stand for?
- Dominance, Influence, Steadiness, Conscientiousness — the four behavioural styles the model measures.
- Is DISC the same as personality?
- Not quite. DISC measures observable behavioural tendencies, while frameworks like the Big Five measure deeper trait structures. Both are useful but serve different purposes.
- Can I use DISC to understand my team?
- Yes — DISC is one of the most widely used tools in team development, helping managers understand how each person communicates and responds to pressure.
