No, you do write a complete speech. That's something the executive can react to and what, when final, will be distributed to media, posted on the company website and repurposed into opinon-editorials and maybe even white papers.
What you send the executive off to a place like France with is a point outline, sometimes called "Talking Points." The bet is that, despite tons of audience research, a leader like Marissa Mayer won't feel 100 percent comfortable with the attendees of all the whatevers.
Working from a point outline, rather than a set text, gives her opportunity to read every bit of body language and facial gesture. In response she adjusts her tone and content. You might say she creates a kind of rhetorical dance with the audience. The moves she makes should align with them. If they do, her presentation will be called "authentic."
Instead, according to Dave Smith in Business Insider, Mayer's remarks in France some perceived as "canned." That's the kiss of death in this era when having an authentic conversation with the audience is everything. Here is Smith's panning of Mayer's lack of performance art in France.
This is unfortunate. Someone has to be accountable. My finger points at those responsible for scripting. This does not have to happen again. Yes, Mayer can contcact me at here in the Southwest at firstname.lastname@example.org. We're in the same time zone.
