I’ve called it Model-T development[1]. The Model-T brought standardization to building cars where companies only built to a very specific spec. It didn’t matter that some companies would be better than others, or cheaper/expensive. The point was choice, competition, and interchangeable parts. Granted, I don’t actually know about that, but that’s the end result.
