Yes, we need to study this. "Obviously" is not good enough. People want to find the best use for their time, to get maximum profits. An optimization can be done for some extent by relying on "obvious", but if really you want to maximize productivity, you need to measure things. You need to go from qualitative reasoning to quantitative one. We need not just measure comparative costs of bugs in productions with bugs in development, we ways to measure amount of not found yet bugs, we need to predict speed of bug-hunting in advance, we need a lot of tools to really quantify a development process. To make a decision we need a way to predict future events, it allow to compare consequences of different decisions and to choose one wisely. > Time is money, you age fast on production. Bugs is also money. So we need a way to compare them quantitatively.
