Short answer: Constructive feedback works when you lead with the one point plainly (skip the compliment sandwich), describe a specific behaviour and its impact rather than a personality trait, and end with a concrete change. "Be more proactive" is a verdict with no handle; "flag gaps before the meeting, not in it" is something someone can actually do.
Feedback is where good intentions go to die. We soften the giving until the point disappears, because feedback feels like a verdict on the person. It isn't - it's information about one behaviour in one moment. Here's how to give it so it lands.
The compliment-criticism-compliment sandwich is built for the giver's comfort, not the receiver's clarity. Padding the point with praise teaches people to brace whenever you compliment them, and lets them file the real message under "minor."
Lead with the one thing, plainly:
"I want to flag one thing: the last two deadlines slipped without a heads-up, and it left the team scrambling. Can we figure out what's getting in the way?"
Warmth belongs in your tone and in the fact that you cared enough to say it - not in a layer of compliments that muffle the message.
"Be more strategic," "show more ownership," "work on your communication" - these are verdicts on who someone is, with no handle to grab. Worse, character feedback puts people on the defensive, because you're grading their personality, not describing an action.
Use situation, behaviour, impact:
"In Tuesday's review, the client asked twice for the risk section and it wasn't there. Next time, can you flag gaps before the meeting rather than in it?"
And keep impact as your experience, not a proven fact: say "it landed as dismissive," not "you were dismissive." One is data they can use; the other is a charge they'll fight.
"Great job" is kind and does nothing, because they've no idea what to repeat. Praise is feedback - make it as specific as your criticism:
"The way you cut that update to three lines is exactly why the client actually read it. Do that on the next one."
Name the exact behaviour and its effect, so good work repeats. (Praising the person - "you're so smart" - quietly raises the stakes and makes people play it safe; praise the thing they did instead.)
Half of feedback is taking it well. The instinct is to defend on contact - "well, actually, the reason for that was…" - before you've even heard it fully. But hearing feedback and agreeing with it are two different things.
Take it in, thank them, ask a question, decide later:
"Thanks for telling me - let me sit with that. Can I ask what it looked like from your side?"
Defend early and you never find out what was true in it. You can weigh whether it's right later, once you've actually got all of it.
Feedback with no follow-up teaches everyone it doesn't matter. As the giver, notice and name the change ("you've been flagging gaps ahead of meetings since we talked - it's made a real difference"). As the receiver, report back what you did. The loop is where feedback turns into trust.
Lead with the specific point in one sentence, describe the behaviour and its impact (not a personality trait), and end with a concrete change. Skip the compliment sandwich
Because it's built for the giver's comfort, not the receiver's clarity. Burying the criticism between two compliments lets people file it under "minor" and teaches them to brace every time you praise them. Lead with the point and keep the warmth in your tone.
Describe a specific behaviour in a specific moment and its impact, rather than a trait
SBI stands for Situation-Behaviour-Impact (from the Center for Creative Leadership): you name the situation, the specific thing the person did, and the effect it had. It keeps feedback pointed at an action in a moment instead of a judgement about their character.
Separate hearing from agreeing. Take the feedback in, thank the person, and ask a clarifying question before you respond - then decide later, in your own time, whether it's right. Defending in the first two seconds means you never learn what was true in it.
