The document discusses how user experience (UX) research can fit into an agile development process. It outlines three main options: 1) conducting UX research in parallel sprints simultaneously with development sprints, 2) using staggered sprints where UX research precedes development sprints, and 3) using techniques like rapid iterative testing and evaluation (RITE) and design studios that allow for quick UX research within sprints. It emphasizes the importance of UX researchers being integrated into scrum teams and participating in activities like sprint planning and retrospectives. Conducting just enough research up front or in a "sprint zero" is also recommended to help guide development without slowing it down.
