Useful feedback separates what you observed from what you inferred. Before the conversation, identify the concrete situation, the behavior you saw or heard, and the effect it had on the work, the team, or the person receiving the feedback. This keeps the discussion grounded in evidence instead of labels such as “unreliable” or “not collaborative.”
Also decide what the conversation should make possible. Positive feedback should help someone understand what to repeat. Developmental feedback should clarify what needs to change without pretending you know the other person's intent. In both cases, leave room for their perspective and agree on what happens next.
Common mistakes
Waiting too long to give feedback
After two weeks, the situation, exact words, and impact are often difficult to reconstruct. Address observations as soon as practical instead of saving them for a later catch-all conversation.
Talking about the person instead of with them
Taking criticism to a manager first can quickly feel like a complaint. A useful first question is: Have you already said this to the person directly?
Presenting judgments as facts
Words such as unreliable or difficult are evaluations. Describe visible behavior and its concrete impact instead. Nonviolent Communication can help you prepare through observation, feeling, need, and request.
Methods used for feedback reflection
Is a particular occasion coming up?
One conversation for a whole year of work.
“Have you already said it to the person directly?”
I ask this almost every time someone tells me about a colleague's behavior. Direct, timely feedback gives the other person a chance to understand the situation and respond before an observation turns into a complaint passed through someone else.
