The analysis process in an iterative product development

One of the main problems that almost any team faces when moving to agile methodologies is the lack of detailed requirements. In other words - the problem of an incomprehensible backlog. In this report, I would like to talk, how we have improved the requirements development process by involving the dev team in the analysis process as part of sprint planning and product backlog refinement meetings (PBR, grooming), as well as refining requirements during development. This report will be useful for analysts, product managers, and any member of the agile development team.
