Product Management

This is a founder and PM toolkit that actually gives you templates you can use today, not product theory. It walks you through customer interviews, outcome roadmaps, prioritization scorecards, kill criteria, and PMF measurement with copy-paste templates and decision trees. The philosophy is evidence-based and execution-focused: label your signal strength, define metrics with formulas and data sources, set kill criteria before you start building. Useful when you need to write a PRD, build a roadmap, run discovery, or figure out what to stop working on. The "bridge migration" pattern for retiring features without losing users is worth the price of admission alone.
