## Summary

Stephen Haus and Lucian Chea Hunt of Opulo discuss the Engineering Validation Test (EVT), Design Validation Test (DVT), and Production Validation Test (PVT) phases of new product introduction. They contrast the rigid, high-stakes processes used at large companies like Form Labs with the compressed, agile workflows possible for smaller teams using in-house 3D printing and tools like the Lumen. The hosts emphasize that while the framework is universal, the execution must adapt to the company's scale, supply chain, and risk tolerance to avoid costly errors like cutting the wrong mold.
