What component of effective feedback is demonstrated when you tell what the feedback will be about in the first sentence?

Answer

I would say it should be specific; direct and to the point

Explanation

Effective feedback should be specific. This is to say that the feedback has to be concrete and related to a particular, measurable performance goal. A feedback that explains what is about in the first line contains a clear expectation for the workers and their performance. Thus, a feedback should be clear, easy to understand and directly formatted.
