## Summary

Rob Carl, Founder & CEO of Global NPI Solvers, explains the 'Pre-Ascent Protocol' for New Product Introduction, arguing that a working prototype is merely a sketch, not a map to mass production. He details how 'architecture freeze' on voltage rails, thermal envelopes, and antenna placement prevents costly re-spins, using a smart home controller scenario to illustrate the risks of late-stage changes. The conversation emphasizes using DFMEA and PFMEA as early-warning systems to catch design flaws, such as snap-fit tolerances, before they become field failures or scrap.
