How much jargon has slipped into your day to day work and even your presentations? ADR, JAHCO, NQF, PAYOR MIX, HIPAA, RAPPS, TIPS, CHIRP?
Remember your audience is coming from chaos: emails, children, no breakfast, traffic, a request for a divorce, an elderly parent with another fall. So, consider this: spell it out, say the words, explain in lay terms what the term is and what it means. And mostly what its importance is for this presentation: for THIS presentation.
It is too easy to rely on what we think the audience knows...they don’t often know the most important part of your presentation which is ‘your take’ on the data, the stuff, the topic, the thing that they came to hear about. They all have a number of boxes in their heads and your jargon and your content is ready to go into those boxes with a self-assured “Oh, I know what that means!”
Make sure that your take on things has no prepared box. Be different enough to present what has to roam from box to box so that they cannot dismiss what you say with “Oh I know that!” Instead they have to respond with “Uh, I never heard it presented that way before!”
