What a high D is like at work
At their best, a high-D colleague is the person who makes things happen. They make decisions when others hesitate, take on hard problems, and push through obstacles. They like challenge, competition and owning the outcome.
The same traits cause trouble when they're overplayed. High Ds can be blunt to the point of rudeness, impatient with detail, and quick to decide before everyone's caught up. They often don't notice the effect they have, because they'd prefer people were direct with them too.
- Control over how, visible results, challenge, speed.
- Slow decisions, vague goals, long meetings, being micromanaged.
- Short. Agenda in advance, decisions and blockers first, clear actions.
- Straight and soon: what happened, the impact, what you want instead.
- The outcome, deadline, budget and authority. Then step back.
- Steamrolling quieter colleagues; friction with high S and high C.
What motivates them
- Control over how the work gets done. Tell them where to get to, not how to get there.
- Visible results. Clear targets, measurable progress, wins they can point to.
- Challenge. A stretch goal or a problem nobody else could solve.
- Speed. Fast decisions and short loops. Waiting is the thing they hate most.
What frustrates them
Slow decisions, vague goals, long meetings without outcomes, being micromanaged, and feeling that someone else is in control of something they're accountable for.
Running their 1:1s
Keep them short and useful. A high D wants to know what the meeting is for before it starts.
- Send the agenda in advance, even if it's three bullet points.
- Lead with decisions and blockers, not updates they've already given you.
- End with clear actions and who owns them.
- Skip the long warm-up. A quick check-in is fine; ten minutes of small talk feels like time wasted.
A good opening line: "Two things I need a decision on, then whatever's blocking you."
Giving feedback
High Ds respect directness and find softened feedback confusing or weak. Say what happened, the impact, and what you want instead, in that order.
"In yesterday's meeting you cut Sam off twice before he'd finished. He's stopped contributing in those meetings, and we need his input on the rollout. Let him finish before you respond."
Don't save it up for a quarterly review. Give it the same week, ideally the same day. And expect them to argue back. That's usually how they process it, not a sign it hasn't landed.
Turn this into advice for one person on your team.
Delegating to a high D
Hand over the outcome, the deadline, the budget and the authority to make decisions. Agree up front which decisions they must check with you, and leave the rest to them. If you hand them a task and then hover, they'll either disengage or start fighting you for control.
Under pressure
Under stress, high Ds tend to become more controlling, more impatient and more blunt. They take over, decide alone and stop listening. If you see that, give them a specific piece of the problem to own, and remind them who else needs to be heard.
Where friction starts
- With high S colleagues, who find their pace and bluntness unsettling. The S goes quiet; the D reads silence as agreement.
- With high C colleagues, who want to check the detail before deciding. The D sees obstruction; the C sees recklessness.
- With other high Ds, when two people both want control of the same thing. Separate their territories clearly.
The fix is usually to name the difference: "You want the decision now; Alex wants to check the numbers first. Let's give Alex until Thursday, then decide."
Common blends
- D with strong I: persuasive and fast. Great at rallying people behind a goal; can overpromise.
- D with strong C: exacting and results-driven. High standards for themselves and everyone else; can be hard to please.
Quick checklist
- Give them the goal and the authority, not the method.
- Keep 1:1s short, with an agenda and a decision.
- Give feedback straight and soon.
- Protect quieter colleagues from being steamrolled.
- Explain process in terms of the result it protects.
Questions managers ask
Are high-D people good managers?
Often, in fast-moving situations that need decisions. They can struggle when a team needs patience, listening or steady support. Like every style, they do best when they know their blind spots.
How do I push back on a high D?
Directly, with facts, and without drama. High Ds respect people who stand their ground. State the problem, the evidence and what you need, and let them argue. They usually move faster than you expect once they're convinced.
Why does my high D ignore process?
Because they experience process as friction between them and the result. Explain what the process protects in outcome terms, and they're much more likely to follow it.
