> more output for less $$
That's a trap: it's not obvious for those without experience in both business and engineering on how to estimate or later calculate this $$. The trap is in the cost of changes and fix budget when things will break. And things will break. Often. Also, the requirements will change often, that's normal (our world is not static). So the cost has some tendency to change (guess which direction). The thoughtless copy-paste and rewrite-everything approach is nice, but the cost goes up steep with time soon. Those who don't know it will be trapped dead and lose business.
Predicting costs may be tricky, but measuring them after the fact it's a fair bit easier.
Without prediction is like landing B787 totally blind without any instrumental or visual.
It will not just hurt, it will kill a business.
