How much jargon has slipped into your day to day work and even your presentations? ADR, JAHCO, NQF, PAYOR MIX, HIPAA, RAPPS, TIPS, CHIRP, MOB, HOPD...
Great presenters simplify and illuminate as not everyone in the audience knows what all those letters are! So, consider this: spell it out, say the words, explain in lay terms what the term is and what it means. What is its importance for this presentation? For THIS presentation!
In most cases, the audience doesn't know the most important part of your presentation which is ‘your take’ on the topic, the data, the 'thing' that they came to hear about. They all have a number of boxes in their heads and your content (or jargon!) is ready to go into one of 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 so they have to roam from box to box and 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!”
