This is usually easy: to make sure that the information in a presentation is correct. That there are no mistakes in the data. That it’s complete. That we didn’t miss anything.
This is usually much harder: to make sure that our audience gets it. What does the data mean? How does this work? Why does it matter?
This is the least we should strive for.
Too many presenters stop at being correct. They consider their job to be to deliver the info.
Their job is to create understanding. The purpose of a presentation isn’t to be delivered but to be understood – if not to change minds.
When someone grants us 30 minutes of their time, the least we should do is to speak with clarity so they get what we mean.
