But there is no proof it takes 8x as long or costs 100000s or more because of that; if you can prove that then many companies will say, yup, that’s a shoe in, let’s rewrite! I have been in a lot of rewrites and more often than not, it did make the tech folks happy, but it did nothing, immediately or middle/long term, to the bottom line or the productivity. Worse; the productivity plummets at first because a lot of new things have to be learned.
