What distinguishes the iterative test-to-failure approach from the traditional aerospace design-to-success philosophy?

It intentionally pushes hardware to its absolute limit to maximize data acquisition

The test-to-failure strategy deliberately subjects hardware to extreme conditions to identify the exact point where the structure breaks. Unlike the traditional design-to-success approach, which aims to build a perfect unit initially through conservative margins and extensive simulation, the iterative method values real-world data gained from hardware destruction. This allows engineers to learn about the physical limits of the vehicle, which helps avoid similar failures during actual launches.
