The debt metaphor is absolutely correct from my perspective, right down to interest. Yes, the debt part is getting something quicker (a shipping product) in exchange for a liability on the balance sheet than we would if we spent more time (reduced sales) and created it in a way that it left no mark on the balance sheet. The interest is generally expressed after the fact in terms of less maintainablity (eg. other changes are more expensive to make) or less performance or a combination of both.
