There are countless software projects that have never seen the light of day because the developers spent all the time polishing the back of the cabinet (and the product managers designing the door handles), and nobody did anything about the actual drawers.
You've seen the survivors of the process which have ugly backs of the cabinets because the developers started on the actual drawers and, because more likely than not it was somebody elses money paying for back-of-the-cabinet-polishing, and they got stopped at the end.
Also, if I have to delay the building of my kitchen because the cabinets are late, and I call the shop and they cheerfully tell me that they were ready yesterday but they haven't finished polishing the backs, oh man, I don't know how happy am I going to be about their excellent craftsmanship, you know?
