A thought that occurred to me - another metric we use in the real word would be what I'm calling "solidness" or "weight." I.e. if you see a house and a similarly sized tent, the apparent difference we see between the two is weight - we can probably pick up the tent and walk away with it. In a sense, that's a useful way to describe software to non-technical users. We can throw something quick and dirty together, but it would be light as a feather, and carried away by any kind of load whatsoever. Or we can build something more solid to last longer, but it should be clear that that will take more effort.
