As a manager, how do you share appraisal feedback?

We've seen stories and videos of employees receiving appraisals from their managers. (Of course, more of hatred)

Now, as a manager, how did you prepare yourself to share such feedbacks, both positive and negative. Did your team respect you less or more after appraisals?

There'd be employees who deserve more but due to higher management restrictions, they're unable to get the deserving number. How do you prepare in such situations?

How were positive appraisals delivered?
