Each DISC style has its own motivation drivers. D styles are driven by control, challenge, and results. I styles by recognition, novelty, and social connection. S styles by security, belonging, and appreciation. C styles by accuracy, autonomy, and intellectual respect. Knowing someone's motivation drivers allows you to influence them ethically: offer a D a challenge, not a compliment; offer an S stability, not a surprise promotion. Misaligned motivation is one of the most common reasons coaching interventions fail.
In practice, offering someone the wrong reward doesn't motivate, it can even demotivate. Publicly praising an introverted C style who hates being singled out, or giving a repetitive, solitary task to an I style who needs social contact, produces the opposite of the intended effect, even with the best intentions.
A manager rewards his top salesperson (D profile) with a friendly team night out, thinking it would please her. She would have far preferred a new sales challenge with a clear target to hit: social recognition is not what motivates her most.
Motivation drivers are not the same as skills: someone can be motivated by social recognition without being particularly good at public relations, these are two separate dimensions.

Watching what they spontaneously invest effort in without being asked often gives a better indication than asking them directly.
