Software and houses are not similer.
Of course they are.
For one thing, when people ask an architect to design a new home for their family, it's perfectly normal to call him back six months later in the middle of first fit and say that actually what they need is a skyscraper. With a secret underground lair. And access to open water, so unfortunately the urban site where half of it currently sits is no good and the whole thing will need to be relocated to the nearest coast. And the building regs have suddenly changed, so now instead of concrete and rebars, the whole thing has to be made of environmentally friendly engineered wood materials.
Moreover, just like houses, we have thousands of years of experience building software now. We've become pretty good at telling in advance which techniques will be needed, what order the different components will need to be built in, and especially estimating how long it's going to take and what it will cost.
Actually, maybe it is a slightly unfair comparison, because the amateurs who build physical structures, like that mile-long railway tunnel that was drilled from both ends and wound up out of position by absurd amounts like 4mm when they met in the middle, can't really keep up with software development professionals who can build precisely specified interfaces and get everything to fit together exactly on the first attempt.
That's mostly because the tools and processes for doing all of this in the software world are well understood throughout the industry, which in turn is because everyone practising software development has gone through rigorous training taught by people who are themselves experts with years of practical experience to draw upon. Engineers and architects try to do the same thing, but they just haven't quite nailed it yet. I guess software guys have an advantage here because those tools and processes are universal and uncontroversial, so everyone in software does things the same way and software project managers don't really need to co-ordinate their team to quite the same extent that, say, a lead contractor would when building a house.
But apart from that slight advantage because software development is so much better understood, I think it's perfectly reasonable to compare building a house to building software and expect things to work the same way. There's really no qualitative difference at all, and basically the same processes work just as well for both tasks.
