In product development (especially Agile environments), a Backlog is a prioritized list of tasks, features, or user stories that need to be completed. Think of it as the team’s to-do list for building and improving a product. Items in the backlog can include new features to design or develop, bugs to fix, research to conduct, or improvements to make for better UX. The backlog is continuously updated and re-prioritized by the product team as needs change or feedback comes in. For UX designers, backlog items might involve creating a new prototype for a feature, conducting a usability test, or refining a design based on user feedback. By working from the backlog, teams ensure they are always focused on the most important tasks first. A well-groomed backlog helps maintain an efficient workflow and ensures that user-centric improvements are given proper priority among development tasks.
