What's One Thing? changes feedback from a broad invitation into a bounded pull request. Instead of asking whether someone has any feedback—a question that makes “no” easy and feels risky when directed upward—a leader assumes an improvement exists and asks for one specific item. The prompt can target the leader's behavior or a shared setting, such as one change that would make Monday's meeting more efficient. Requesting only one item lowers preparation and emotional stakes while clearly signaling a desire for coaching. Repeating the question with different people and listening for themes gives leaders access to information others may already share privately about what makes working with them harder.
Origin
Heen described “What's one thing?” as a frequently used question for integrating feedback into daily leadership.
Core principles
- 01Specific prompts are easier to answer than broad invitations
- 02Assume there is something useful to improve
- 03One item lowers the stakes
- 04Leaders must actively pull feedback upward
- 05Receiving visibly shapes feedback culture
How to run it
- 1
Bound the topic
Select a concrete behavior, meeting, or working relationship instead of asking about everything at once.
Pro tip A question tied to a recent recurring meeting is easy to answer.
- 2
Ask for one thing
Phrase the question so that one improvement is assumed, not optional. Ask what one change would make a difference.
Pro tip Use the question casually in daily work to lower the stakes.
Watch out “Is there anything?” invites a polite denial.
- 3
Receive visibly
Listen, clarify, and take the answer seriously without demanding that the giver defend every detail.
Pro tip Model the receptiveness you expect from others.
Watch out Feedback upward already feels risky; defensiveness teaches people to stop offering it.

Collect themes
Repeat the prompt with different people at different times and look for patterns that identify a meaningful development target.
Watch out You cannot promise to change every item, but you should not pretend the pattern is invisible.
In the wild
A leader notices that people's energy flags in the Monday morning meeting. While walking down the hall, the leader asks a colleague for one thing the group could change to make the meeting more efficient rather than requesting general feedback about leadership.
→ The colleague receives a low-stakes, specific invitation to supply actionable coaching.
Common mistakes
Asking if feedback exists
The wording allows a safe, polite answer that everything is fine and leaves the giver to define an enormous scope.
Failing the receiving test
A leader who reacts poorly confirms that candid upward feedback is dangerous.
Is it for you?
Best for
Leaders who receive too little candid feedback from people affected by their behavior.
Not ideal for
Leaders who ask performatively but punish, debate, or ignore the answers.

“What's one thing that I'm doing or maybe failing to do that you think is getting in the way, or what's one thing that, if…”
“You have to assume there is.”
“If you want to know what's on that list, you have to ask, and you have to ask in a way that persuades them that…”
