Understanding DISC

Millions of professionals have used the DISC personality assessment to improve their relationships, build stronger teams, and communicate more effectively.

The D Personality Type

How to identify a D

Natural behavior

A person with the "D" personality type is likely to be direct, assertive, independent, and decisive. They are intense competitors that thrive with ambitious goals and challenges, preferring action over analysis when they need to complete a task.

D's are also generally comfortable with conflict, and may push harder than other more passive personality styles to assert their will and take control of a situation.


Someone with a D personality type will typically speak confidently and articulately, but will be quick to end a conversation that isn't going anywhere. Their ideas will be high-level, opinionated, and at times blunt, but you usually will have no problem understanding where they stand on an issue.

Communicating with a D

In person or on the phone

  • Project your voice and speak with a confident tone.
  • Present ideas at a high level without going into detail.
  • Use clear, direct sentences rather than long expressive ones.
  • Don't get frustrated when they interrupt you.
  • If you're calling them on the phone, first ask if they are available via email or text.

In writing

  • Limit an email to three sentences or less.
  • Use an informal greeting.
  • State the purpose of an email in the first sentence (example: "Andrew," rather than "Hi Andrew,").
  • Use casual language and abbreviations.

Working with a D


D's are motivated by their deep desire win and produce results, so they tend to gravitate towards leadership positions. They need to constantly be working towards an ambitious goal to feel fulfilled in their work, and will grow bored or frustrated in a conservative environment that moves at deliberately cautious pace.

As a Leader

D's can be a powerful force for action on a team, with a keen ability to focus and push a task through to completion on a deadline. They are the type of people that "just do it."

They are also able to make decisions with limited data, and are flexible enough to pivot as more information emerges. Being so comfortable with the unknown makes them excellent leaders in chaotic times.

Under Stress

Under stress, D's can become impatient and aggressive. Their natural approach to problem solving is to take control and act quickly, so if others expect them to cooperate, they may rub a team the wrong way and cause conflict.
