When a presenter has been identified in advance, there’s no reason to delay the coaching of the presenter until the night before or the day of the Forum meeting.
A Forum member recently wrote to me and summed up nicely the advantages of advance, in-person coaching:
I become nervous when the coaching is happening for the first time right before the meeting. One to two weeks before is ideal because, both when I’ve coached and been coached, it has given me as the presenter (and the person I coached) a chance to let the presentation “steep” and therefore be stronger. It also allowed me to come up with other ideas before the presentation as well. And based on my experiences both ways, face-to-face was definitely more satisfying than over the phone. Being able to see the other person as they wrestle with the topic allows the dimension of body language to enlighten, and in my experience makes for a less rushed experience than a phone call.
