The DISC model is used in sales in two ways: either as a psychology test that unfolds over 45 minutes, or as a practical navigation tool you use in real-time during a conversation.
The first is too slow. The second works. Here’s what you actually need to know.
The four types — concise and operational
D — Dominant
You recognize them by
Speaks directly. Interrupts. Asks about results and ROI. Impatient with details.
Typical mistake
Too much rapport-building and too many features. They want the conclusion.
What you do
Go straight to what it gives them. Be brief. Let them set the pace. Give them a decision to make.
I — Influential
You recognize them by
Enthusiastic, talks about relationships and possibilities. Uses superlatives. Hates details.
Typical mistake
Diving into tech and processes. They lose focus.
What you do
Set the vision. Talk about what others are doing. Give them a good story. Book the next meeting with them — they are rarely the final decision-maker.
S — Steady
You recognize them by
Calm, asks clarifying questions, willing to listen. Avoids confrontation. Rarely says a direct no.
Typical mistake
Pushing for a quick decision. They close off.
What you do
Give time. Reduce the risk perspective. Use references and testimonials. Ask explicitly: “Is there anything holding you back?”
C — Conscientious
You recognize them by
Asks detailed questions. Wants documentation. Skeptical of big claims.
Typical mistake
Vague claims and emotional selling. They don’t believe you.
What you do
Be precise. Give data. Proactively admit limitations. That increases credibility. Let them research — they will anyway.
The most important rule
DISC is not a box you put people in. Most have a primary and a secondary type. A D with high C will want ROI data — not just the conclusion. An S with high I will want to hear what others are doing — but will need time to think it through.
Use it as a compass, not a diagnosis. And don’t assume you know the type after 2 minutes. Observe more than you conclude.
