Well Nick, I think you just answered it when you said "I want to hear from them in regard to ideas for improvement, if there is anything else I could be doing to help them be more effective in their position, etc." Make that the starting point of the meeting, and see what they have to say. If you're as personable as a manager as you are as a colleague, I'm sure you'll get some useful feedback. Of course, you can follow that up with your own feedback, whether it's responding to their thoughts or mentoring through praising their strengths and offering advice to bolster their weaknesses. At least that's pretty much how I have done my own, which I have gotten a decent response from. And it goes without saying that mine incorporate a fair amount of wit and sarcasm, as well. Never forget that part. Gotta have fun. 😉
