I enjoyed your comment, and just want to point out that there are two separate issues at play here: 1) The quality of the end product (what the target audience sees and interacts with) 2) The quality of the underlying implementation (the hidden stuff that makes it work) They are not completely independent (e.g. uncertainty in the product design has strong implications about time spent polishing the code). But the distinction is important, and it can be worthwhile to analyze them separately.
