This document outlines the PDMA NPDP Stage-Gate framework for new product development. It consists of 5 stages: Discovery, Scoping, Development, Testing & Validation, and Launch & Commercialization. Each stage involves cross-functional teams and deliverables. Gates 1-5 involve project reviews to determine whether the project proceeds or recycles. The goal is to develop a proven product prototype and updated business case through this cross-functional stage-gate process.
