Your report should have a clear sense at all times of what your expectations are and where he stands. If he is often wondering, What does my manager think of me? then you need to dial up your level of feedback. Don’t assume he can read between the lines or that no news is good news. If you think he is the epitome of awesome, tell him. If you don’t think he is operating at the level you’d like to see, he should know that, too, and precisely why you feel that way.
