There are some great articles floating around about how to craft a compelling brand or product or data story that holds people's attention. But, as a playwright, I’d like to draw your attention to this book by David Ball. The book was written for actors, to help them closely read play texts. But I like to think of it as a manual for writing narrative.
In the book, Ball breaks down narrative into three sections which I find way more helpful than Beginning, Middle, and End. He breaks plot into: Stasis, Intrusion, and the Struggle for New Stasis. This is a much more active way of thinking about story - if Stasis is the status quo, the way things are now, then Intrusion is exactly what it sounds like - a disruption. An inconvenience. And the Struggle for New Stasis is your heroic attempt to solve the problem of the Intrusion.
Next time you have to give a presentation, think like a playwright.
