This blog post is about flexing your approach to match the context: the audience demographics, the time of day, the setting, the subject matter, the intention for the meeting, and more.
It was the end of a long day...after several long days...and the group was slow to move into their chairs from the break. The room was darkened for Brian's slide show, and he began to present content about some studies, using academic terms and building his "evidence" to make his point that related to points made earlier in the day.
Unfortunately, the group was simply too tired, his presentation too long, technical, and jargon-laden for them to relate, and while they were well-educated, they weren't an academic group. Brian's well-intentioned idea fell flat with his audience, who was, thankfully, forgiving.
