The document discusses applying the KonMari tidying method to product backlogs. It recommends five steps: 1) define your product vision, 2) find all PBIs and put them in one place, 3) sort PBIs by category, 4) start with easier items, and 5) only keep PBIs that "spark joy" for customers. Organizing PBIs using story mapping and treating them respectfully according to INVEST principles is advised. Tidying the backlog facilitates better decision-making and leads to better products.
