The real skill (that I have never mastered) in leading a good group lies in asking good follow-up questions. The questions that you prepare ahead of time may be lackluster, but if you know how to draw people out a little more, then you can lead a good discussion.
Follow-up questions come when a person has answered, and you come back and say:
“What do you mean by ________?”
“Anyone else have any thoughts on that?”
“Do you mean _______?”
“Why?”
And etc.
Your goal is to make sure that everyone understands the person’s answer and draw out any further insight.
It’s also good to summarize what’s been said. You might say:
“So, we’ve seen that ______, now let’s look at ______.”
“Since we know that _____, then _____.”
It’s not as easy to do as it sounds, and the only way to really learn it is to do it, but it is the one skill that can separate a mediocre leader from a good leader.
