The content of our presentation is what we want to say; it's the information that we think will help our sales team do better, the description of a new process that our colleagues must adhere to, the latest results of our research or the new idea that we want to share. Our delivery of it is how we bring it to life, create a compelling vision with it or use it to motivate or persuade. Being clear about the difference between preparing the content and rehearsing its delivery is essential, if we are to give both disciplines the time they need so that our presentation is as effective as possible.
