Here are a few DiSC training exercises you can incorporate into your next DiSC session to teach skills for modifying behaviors.

Bring a stranger into the the classroom and have participants ask the stranger questions until they can guess that person’s highest behavioral tendency. The point made in this exercise is that you must be able to recognize behavioral tendencies before you can adapt to them.
Pair up high Ds, is, Ss, and Cs and have them sell a product or idea to their opposite behavioral tendency. Have the participants deliver their presentation in a small group or in front of the entire room and discuss options for modifying behaviors to meet the other person’s needs.
Use the DiSC Sales Action Planner, which helps you determine someone’s behavioral style. The action planner gives you suggestions for adapting your behavior to open the call, make the presentation, negotiate, close the sale and maintain positive client relationships.
