Builds structured user personas from research data rather than letting you wing it with assumptions. You get interview guides, templates for demographics and pain points, and frameworks for synthesizing findings into 2-3 actionable personas. The approach is straightforward: conduct interviews, identify patterns, document with real quotes, then actually use the personas for product decisions. It pushes you to base everything on real data and update regularly, which sounds obvious but most teams skip. Good if you're starting product design or need to align a team around who they're building for. The reference guides cover research collection through to applying personas in practice.
