I conferred recently with a couple of knowledgeable and accomplished scientists about a conference at which they hoped to reach a key audience. They had a wealth of information and details they hoped communicate with other decision-making professionals - literally reams of valuable information and science-based recommendations.
One of the first questions I asked was "what do you hope to achieve and, specifically, what do you want people to do as a result of attending your meeting."
The answer - "our goal is to deliver a substantive presentation."
