lol! no surer sign of a junior/naive/ignorant developer or manager than the sentiment "okay, well, let's start from scratch and do it right this time."

big projects generate cruft. there are ways to minimize it, but as you go along there will always be some stuff that doesn't quite mesh with whatever else you've got going on. if you insist on ironing out every single wrinkle (admirable!) you'll never actually deliver a result.

I'm not saying this will fail. green field projects can certainly be a godsend when they produce something better than what they attempt to replace. but they are always a sign of failure. of not being able to work your way out of the mess you made with the first attempt. so that just begs the question: what are you going to do when this attempt gets hard to work with? going to give up and start over again - do it right that time? or...?
