i think the thing that hits home for me here is that when you go back and do the after action report on where the time was spent last year and what it cost its terrifying. of course hindsight is 20/20 and predicting how difficult something is going to be is hard, but when you say we spent $x million on this version update that does y and $a hundred thousand to implement this feature - you think to yourself we would have never made that cost / benefit decision if we had known.
