The document discusses applying the KonMari tidying method to product backlogs. It recommends finding all product backlog items (PBIs), sorting them by category, and only keeping items that "spark joy" for customers. A 5-step process is outlined: 1) define product vision, 2) find all PBIs and consolidate, 3) sort by category, 4) start with easier items, 5) keep only items sparking joy. Story mapping and vertical folding techniques are suggested for organizing the backlog. Applying KonMari principles can lead to simpler, clearer backlogs that facilitate decision-making and development of better products.
