We are all too well aware of the tragedy that is modern software engineering lol. Sadly I too have never seen that situation where I was given enough time to do the requisite multiple passes for proper design...

I have been reprimanded and tediously spent collectively combing over said quick prototype code for far longer than the time originally provided to work on it though, as a proof of my incompetence! Does that count?

Hah my bad, I misread your original comment as you saying you usually get the chance to do multiple passes on a prototype to productionalize it :)
