Good acoustics and sight lines. Comfortable chairs and tables. Usable wall space for charts, maps and other graphics. Accessible, nearby restrooms. Make Effective Presentations .
Few planners are golden-tongues orators, but everyone can learn effective presentation skills.
In other words, do not make the same presentation to a group of businesspeople that you gave to high school parents. Focus on their special interests and you will be rewarded with an involved, alert audience. Do not wait until the last minute. Make sure you and other presenters are not repeating each other, or worse yet, contradicting what each other is saying. Speak from notes, not a written speech, and in as short a time as possible.
