Kit Barber explains why feedback fails: managers deliver it and move on without follow-up. The fix is simple. Schedule the follow-up conversation before you leave the room. That one habit separates teams that improve from teams that don't.
If you've ever given someone feedback at work and 3 weeks later nothing has flipping changed, the feedback wasn't the problem. Most managers stop at the conversation. They say the thing, then they feel better for saying it, and then they move on. But feedback without follow-up is just a complaint with good intentions. You see, the follow-up is the thing that actually changes the behaviour. So as a top tip, diarise the follow-up before you leave the feedback conversation. So don't do it later, do it now. If it's not on your calendar before you walk out the room, it ain't gonna happen. And that one habit is the difference between a team that improves and one that simply doesn't.
