When people write a presentation outline, they usually write questions: "why there is a market opportunity, why we are best to capture it, why it is great to invest in us".
The questions are mental shortcuts for the expert presenter, the answers is crystal clear in her head. The presentation looks incredibly logic on paper, yes, this is exactly what we should be talking about, answer these questions.
Missing though is the actual bridge between the questions and the answers in the head of the expert. Difficult for the audience to understand, or for the junior analyst to work on.
A better way to make a story line as actually write down in super short sentences the answer to these questions. You will bump into issues like repetition, order of arguments, where to go in detail, where not, where buzzwords pop up etc. etc.
