Hi Doyle:
Yes, knowing where there are weakneses is one part, As you say, another is what they neeed to work on.
I think another part is making sure they have a realistic plan for how they're going to make those improvements, and that plan should be very specific. To assist in making that plan work, we can always show we care, support them, and give advice and encouraging appreciation for their effort. I think this helps build trust and respect.
