It's a good analogy if the reader understands it, and it is accurate.

Both are true here. People don't get away with quite that level of nonsense with buildings because even laypeople can see all the essentials, why it would be bad, who to blame if it did happen, etc. So it never happens and doesn't need any kind of illustraing analogy to explain it to anyone.

That DOES happen all the time in software and it's invisible to almost everyone including your own bosses, and does need some kind of analogy to illustrate what's wrong about it, and how wrong, and the nature of the wrongness.

Any other example that actually ever happens, would just be some other equally opaque phenomenon from some other esoteric field, and would by definition be useless as an analogy.

The whole point is so that anyone can see it and conclude "that would be crazy, outrageous, intolerable". Of course it never actually happens.

My house has a hole where a cable tv contractor inserted a coax line that they ran all the way around the house, from the service drop to right outside the living room. This despite the house being wired with coax internally, including between these two points. There was a disconnect where someone had replaced a tee with a coupler some years ago, but this was easy for me to find and fix.

Years later I spoke with an ISP about an install and they proposed exactly the same thing. I think people do this a lot.

I get the point but I do agree that it might not be a good analogy since when building structures people might disagree on where they should go but not on what a wall and a door are. In software your caretfully crafted "house" can just be a convoluted way to get from a to b to someone else.

To me writing a story comes closer to what writing software is. I can't just get an overview of their plans and know right away where I should be connecting the new "room" I want to build. Instead I need to understand what story the author was trying to get across and make my insertion in a way that makes sense with what was there before.
