The Philosophy of Iteration: Nothing was set in stone. I treated the initial high-fidelity designs as hypotheses that required rigorous validation. By focusing on "improving step-by-step," I leveraged real-world feedback to strip away remaining friction and optimize the system for high-stakes industrial performance.
