Other disciplines take more of a walk-before-you-run approach
to engineering and the validation of production readiness. For example, airplane aerodynamics are vetted in a wind tunnel before the first test flight. Before the full-sized bridge is built, a scale model is fabricated to assess load-bearing capacity.
Yet even today, we continue to write software that is unprepared to handle a production load, as if onesie-twosie functional testing
nearly approximated a production workload. It doesn’t. Our deliverables include the part about handling a production load.
