Explain How to Give Useful Feedback

"This is good" tells nobody anything. This explains feedback that lands: the difference between judging something and giving information someone can improve on, the three parts of useful feedback, and how to deliver it so it is heard rather than braced against. For managers, peers, and anyone who keeps being asked for their thoughts and giving mush.

**Explain effective feedback in four parts:**
1. The difference between evaluation (judging) and feedback (information for improvement)
2. The three components of useful feedback: observable, specific, and actionable
3. How to frame critical feedback so it is received rather than defended against
4. A template the user can apply immediately to give one piece of feedback this week
