Over the life of a product, Product Owners maintain an ever-evolving Product Backlog. As features rise in rank, the PO breaks them down into stories, eventually sized small so the team can deliver increments of valuable functionality in an iteration. In this tutorial, we will explore examples of how to evolve a product backlog from vision to iteration acceptance. Participants will practice breaking stories down, with an emphasis on understanding the considerations that guide that process. We will provide several examples from different types of projects/products.
