The point of giving feedback is to encourage the behaviour you want to see repeated, or something you’d like change in the future. Try not to dwell on the past.
Especially when giving corrective feedback. Unless you’re just trying to make somebody feel bad. Otherwise ask them what can be learned, and what they’d do differently next time. Staying future focused gives them a much better chance of doing things differently next time, rather than thinking about and then repeating their past mistakes.
And if you have to give corrective feedback, let them come up with the solution / correction / change. It’s much more powerful if they own it, even if it isn’t exactly what you’d do in the same situation. Even if you think their solution is less effective than yours. Their poor solution enthusiastically implemented is better than your better solution dictated.
