A strong positive reaction from the Audience Members and the visible exhibition of learning are desirable outcomes for any speaker. A larger question, however, is "what impact did the presentation have on job performance?"

It behooves you to make follow-up efforts to determine what changes in behavior, if any, on the parts your audience members resulted from a speaker’s presentation. Have audience members done anything differently since the presentation? Has their behavior changed? Has their performance improved? Do groups handle their responsibilities with greater ease? The simple speaker evaluation rating sheets that audience members complete directly following the presentation don't and can't answer these types of questions.
