This document provides an overview of the Sparkline methodology for persuasive storytelling. The Sparkline involves starting with what currently is, then shocking the audience with what could be. This creates a gap that is the central idea to be addressed. The presentation then moves between past, present and future to prove the point and call the audience to action. It ends by envisioning a new normal with the idea adopted and tools for the audience to implement the idea themselves. Regular retrospective meetings are recommended to improve the process.
