PM Handbook

This handbook has been generalised from PM-only to the whole product function: product management, product design, product marketing, and research/analytics share one operating handbook, one taste loop, and one prediction-scoring discipline.

Read the Product Handbook. PM-specific craft detail (commercial mechanism predictions, longitudinal customer exposure, the economics bar) lives in Craft and Domain Expertise.
