Whether it's a teammate, a mate, or your partner, most feedback goes wrong for the same reason: it arrives as a verdict on the person (“you're lazy / careless / selfish”) instead of a note about a specific behaviour and its effect. People defend their character to the death. They can actually hear a comment about one thing they did.
Ask permission and pick the moment
Unsolicited feedback lands as an attack. A quick opener changes everything, and privacy is non-negotiable — never correct someone in front of others.
Use the behaviour → impact formula
Specific and about effect
“When the report came in a day late, I had to push the client call — that put me on the back foot.” It's a fact plus a consequence. Hard to argue with, easy to fix.
Vague and about character
“You're always unreliable.” It's a label, it's global, and it invites a fight about who you are rather than what happened.
Then hand it back and listen
Feedback is the start of a conversation, not a sentence you pass. After you've said your piece, genuinely ask for theirs: “How did it look from your side?” You'll often learn there was a reason — and either way, they're far more likely to change something they helped decide.
Balance the ledger honestly
- Don't sandwich criticism in fake praise — people see it coming and trust it less.
- Do notice genuine strengths at other times, so feedback isn't the only thing they ever hear from you.
- End forward-looking: agree one concrete thing that'll be different next time.

This is the flip side of handling criticism without getting defensive. See also how to start a difficult conversation.
