The document discusses Adzic's Hamburger Method for vertically splitting user stories into smaller stories. It provides an overview of the method, which involves identifying layers or types of tasks needed to complete the story, then identifying options for each task from least to greatest value. The first "bite" or user story combines the least valuable option from each task. Subsequent bites build on prior bites by enhancing them. The document includes an example application of the method and a quiz.
