Julie is looking at the product backlog to evaluate the prioritization of user stories and consider which feature should make it into her next release.
The product backlog is a prioritized list of all the work that needs to be done to improve the product. It includes features, bug fixes, technical debt, and anything else that needs to be addressed. The product manager is responsible for prioritizing the backlog and ensuring that the development team works on the most important items first.
The product backlog is a living document, meaning that it is constantly being updated and refined. As new information is learned about the product and its users, the product manager may need to adjust the priorities of the backlog.
