Ooh, it's the : build a prototype story!
Dev, ok here's the 2 week built prototype, slammed together wildly fast, no architecture, no seatbelts. Don't push it in a demo.
Manager: this Looks like a finalized project! Except a) and b), fix that, you got a day.
Dev: we should productize it, to make it a solid product, it takes 3 months, then I can add a and b without it starting to smoke when used.
Manager: No, I already shipped it.
