It’s true, there is a difference, but the difference is because your audience is different, not because of a difference in the process you go through. You ask yourself the same questions before starting to organize your thoughts, and the difference will be in your answers–not in the process.
You’re still going to ask yourself: Who am I talking to? What am I talking about? And, why? (That is, what is the outcome I’m looking for? What do I want to accomplish?)
Those questions don’t change regardless of whether it’s a presentation to the board of directors, a presentation to a client, or a relaxed evening with your organization.
The answers change, and that makes the difference. Is it data they’ll use in their project, or information that will guide them through the choice of HMOs? Are you selling to a client, or covering your department’s quarterly progress? Lightening the mood of the evening, or conveying appreciation for a job well done?
Those answers will be your guide as you decide how much or little detail to include, what types of examples and backup data to use, and an appropriate way to get your audience to listen (your opening) and to respond appropriately to your message (your close).
The end product may vary widely, but it’s still the same process: what am I talking about, who am I talking to and what do I want to accomplish?
