Yes, I think most of us here understand the above. The point I've been trying to make is that you learn whether or not you've gotten it right by testing and, if your system is failing to run, or failing, a POST/initialization check, you should probably notice that well before anyone on the team suggests that "it's finished/almost finished."
The situation in which Boeing and U.S. aviation in general find themselves today is one in which announcing vaporware is probably a serious mistake.
